Opt for a Smart Charger

Smart chargers are the industry standard today, thanks to their powerful features and capabilities. Non-smart chargers (or non-programmable chargers) might be cheaper and straightforward to use, however, they only offer basic charging functionality, often lack important safety features. Investing in a high-quality modern charger will enhance your experience and likely last throughout most of your FPV career.

Example of an outdated, non-programmable LiPo Charger (NOT recommended)

A smart charger (or programmable charger) boasts numerous practical features. It can charge various battery types, including the popular LiPo and Li-ion used in drones, and allows you to customize charging parameters such as charging current, cell count, and end voltage. Additionally, smart chargers feature a display that provides essential information like charging progress, battery voltage, and charging current in real-time.

Example of a modern smart charger

Modern smart chargers also offer discharging and storage charging capabilities, addressing most of your battery management needs. Another advantage of smart chargers is their ability to measure internal resistance. Although not always highly precise, this feature is useful for monitoring battery health over time.

Ensure Cell Count Compatibility

It’s crucial to choose a charger that supports at least 6S LiPo batteries, meaning it can charge LiPo batteries with six cells or fewer. In 2023, 4S and 6S LiPo batteries are the most common cell counts used in 5-inch FPV drones, so a 6S-compatible charger should cater to the majority of your charging needs.

For those flying tiny whoops or other micro drones powered by 1S batteries, consider acquiring a charger specifically designed for these smaller batteries. Explore my recommendations for Tiny Whoop chargers here:

Understanding Charging Current Requirements

The charging current for LiPo batteries is determined by two factors:

  1. The maximum charging current the LiPo battery can handle
  2. The maximum charging current the charger can provide

It’s generally safe to charge LiPo batteries at 1C, which means the charging current is equal to the battery’s capacity. For instance, 1C for a 4S 1500mAh battery would be 1500mA (or 1.5A). Some LiPo batteries are advertised to handle fast charging at 2C or even higher. However, be aware that charging at higher rates increases the risk of battery overheating and related issues.

Each charger has a power rating (wattage) and a maximum charging current rating (amps). The maximum charging current a charger can provide is limited by either of these ratings, whichever is reached first. The current is limited by the charger’s power rating and the voltage of the battery being charged (P = V * I).

For example, a 100W charger charging a 4S LiPo battery at 16V would have a maximum charge current of 100W / 16V = 6.25A. Note that the current will decrease during the charging cycle as the voltage gradually increases.

Assessing Charger Power Requirements

A LiPo charger’s power is measured in watts, calculated by multiplying voltage (volts) and current (amps).

If you’re only charging one battery at a time, you don’t require much power. For instance, to charge a 4S 1500mAh battery, you’ll need a maximum of 1.5A x 16.8V = 25.2W (assuming you’re charging at 1C). However, if you want to parallel charge multiple packs simultaneously, the power requirement increases significantly. For example, to charge six 4S 1500mAh packs at once, a charger with over 150W of power is needed.

It’s important to note that you don’t always need to meet the exact power requirement. You can still charge the same number of batteries at once with a lower-power charger, but charging will be slower due to a reduced current.

Supported Battery Types

While it’s beneficial for a charger to support various battery types, FPV drone pilots don’t need an extensive range. Primarily, we require support for LiPo, Li-ion, and LiHV (same type of battery as LiPo but with a higher end voltage of 4.35V per cell) batteries. Having NiMH support can be useful for rescuing over-discharged LiPo batteries that cannot be recognized by the charger. However, some newer chargers come with a “trickle charge” feature, which serves the same purpose, making NiMH support less crucial in those models. We’ll discuss the trickle charge feature in more detail in the next section. While some chargers may support NiCad and PB batteries, these types are less relevant for pilots who only fly multirotors.

Understanding Charger Modes

In this section, we’ll discuss common modes in modern smart chargers. A decent charger should at least offer “Balance Charge Mode”, “Discharge Mode”, and “Storage Charge”. Other modes are nice to have but not as essential.

Balance Charge

This mode is the safest way to charge your LiPo batteries, and you’ll likely spend most of your charging time using it. You’ll need to plug in both the main connector and balance connector so the charger can read the voltages of all the cells. The charger will automatically balance the cells during the charge cycle to prevent issues.

Fast Charge

This mode charges batteries faster because it doesn’t monitor and balance individual cell voltages. Instead, it only looks at the overall voltage of the whole pack, which carries the risk of overcharging one or multiple cells. You may not see this mode in most chargers nowadays as it’s deemed unsafe for charging LiPo batteries. We don’t recommend this mode unless you’re experienced and know what you’re doing.


In this mode, the charger reduces the LiPo battery voltage to its lowest allowed level (e.g., 3V or 3.3V, depending on the charger and settings).

Storage Charge

This mode charges or discharges the battery until the voltage of each cell reaches 3.85V, making it suitable for storage.

Trickle Charge

Batteries that sit for long periods may self-discharge, causing voltage levels to drop. If a cell’s voltage is too low, the charger may not be able to detect it or the entire battery. Trickle charge mode slowly pumps current into the battery to revive dead cells. Keep in mind that battery resurrection depends on cell health, and some batteries may be beyond recovery.

Considering the Number of Channels

When selecting a charger, it’s important to consider the number of outputs or channels it has. This will determine how many batteries you can charge simultaneously.

Toolkitrc M4pocket Lipo Charger Balance Charge

Single-output chargers can charge only one battery at a time. However, if you connect a parallel charging board, you can charge multiple batteries simultaneously too. This is a more cost-effective option, but it requires some knowledge on how to parallel charge safely.

Chargers with multiple channels or outputs allow you to charge several batteries at once without the need for a parallel charging board. Each output functions as an independent charger, enabling you to charge different batteries regardless of their battery type, capacity, voltage level, or cell count. Multi-channel chargers are more expensive but offer greater flexibility and faster charging.

Don’t Overlook Balance Current

What’s balance current in a charger?

The balance current of a LiPo charger refers to the current used by the charger to balance the voltage levels of individual cells within a multi-cell LiPo battery during the charging process. Balancing the cells ensures that they all have equal voltage levels, which is essential for maintaining the overall health, safety, and longevity of the battery.

LiPo chargers typically have a balance current rating, measured in milliamps (mA), which indicates the maximum current that the charger can use to balance the cells. Higher balance current ratings generally lead to faster balancing and shorter charging times, while lower ratings may result in longer charging times due to slower cell balancing.

Cheaper chargers tend to have lower balance current ratings, such as 0.2A/cell, while higher-end chargers may have higher balance current ratings, up to 1.6A/cell or even higher. It is important to choose a LiPo charger with a decent balance current rating to ensure efficient charging and minimize the time you spend waiting for your batteries to finish charging.

AC and DC Inputs: Which Is Better?

When selecting your first LiPo charger for an FPV drone, the type of power input—AC (Alternating Current) or DC (Direct Current)—is a crucial consideration. For those new to the hobby, opting for a charger with AC input might be more convenient since it can be powered directly from a wall socket. In contrast, chargers that only accept DC input requires a separate power supply unit (PSU) or a battery to operate. However, having a DC input could be beneficial if you need to charge batteries outdoors. Some chargers offer both inputs, adding to their versatility.

It’s important to note that AC chargers typically deliver lower power due to their built-in power supply, which is not always the most powerful, thus limiting the output power. Conversely, with a decent external power supply, DC chargers can generally surpass the performance of their AC counterparts. Using a separate PSU might sound complex and costly. Yet, the advantage of higher output power becomes apparent when needing to charge multiple batteries simultaneously via parallel charging—a method that, despite its efficiency, raises safety concerns.

The trend towards multi-channel chargers capable of charging several batteries concurrently is growing. These chargers often include a built-in power supply and support AC input, making them highly user-friendly and convenient.

For a secondary charger, consider a small, portable model that supports both XT60 and USB-C inputs. While perhaps not the most powerful for daily use, such chargers are exceedingly compact and convenient for travel and field charging. You could avoid the need to carry a charger by having a more charged LiPo batteries. However, consider the logistics: assuming each flight lasts approximately 5 minutes, flying for two hours would require 24 LiPo batteries—that’s a lot! Having a charger on hand allows for recharging empty batteries while flying, potentially saving money and reducing the need to bring so many LiPos.

Choosing the Right Power Supply for Your Charger

When selecting a charger, you may need to consider the power supply. Some chargers have a built-in power supply, allowing you to plug them directly into an AC wall socket. However, many LiPo chargers require an external power supply (PSU), which you may need to purchase separately.

You can buy PSUs specifically designed for LiPo chargers or modify computer/server PSUs for a more cost-effective solution if you have the necessary skills.

Consider the following when choosing a PSU:

  1. Power: The PSU’s power should be higher than the power demand of your charger. An overpowered PSU won’t make your charger more powerful, but it will be more reliable and future-proof. An underpowered PSU may cause overheating and burnout issues. If needed, consider setting a power limit on your charger to protect the PSU.
  2. Output Voltage: The PSU’s output voltage should be within the input voltage range of your charger.

Here are some PSU options based on their power ratings:

The ToolkitRC P200 PSU (review) is also worth considering. It’s a versatile 200W power supply you can use for various tasks. It features adjustable voltage output and current limit, is compact in size, and has a USB-C output for charging mobile devices and cameras.

How Much You Should Spend On a LiPo Charger

A LiPo charger is a long-term investment in the RC hobby, as it will likely last for years, much like your radio transmitter and FPV goggles. Therefore, it’s wise to allocate a reasonable budget for a quality charger instead of opting for the cheapest option.

The most expensive charger isn’t necessarily the best, but good quality chargers often come at a fair price. Before focusing on the cost, consider what you actually need from a charger. Write down your requirements and find chargers that meet your needs. If you don’t require certain “fancy features,” don’t include them in your list, and prioritize the essential features that will serve you best in the long run.


Choosing the right LiPo charger for your FPV drone may seem like a daunting task, but with the right guidance and understanding of your specific requirements, you’ll be able to make an informed decision. In this post, we’ve explored various charger options, power requirements, and essential features to help you find the charger that best suits your needs and budget. I will continue to keep this list of recommended LiPo chargers up to date. Please leave us a comment if you have any questions.

Happy flying and charging!

What about the HTRC T400 pro ? Thanks

Oscar 25th June 2024 - 4:44 pm

It’s quite an old charger, and frankly the specs/features don’t quite match the modern chargers. For the same price you can get a better/newer one.

Johan-Mark 26th May 2024 - 5:01 pm

The SKYRC B6AC NEO is a variant that also has an AC input. Might be worth to check it out for some people. I personally like it. It is bigger (I believe in height mostly) but still very small, especially for an AC charger.

Hiks 30th April 2024 - 2:12 pm

Thank you for providing such good information for beginners. Let me ask you a few questions while watching.
1. As of April 2024, is the charger you recommend the same?
2. Under the premise of using the drone until it is folded, which charger do you think is the best cost-effective?
3.And do you use two, one for charging at home and the other for charging outside? Is it possible to cover everything with just one?

Oscar 30th April 2024 - 4:13 pm

1. This post was last updated March 2024 (you can find the update date at the beginning of the aritcle).
2. That depends on your requirement, there isn’t a charger that ticks all the boxes. Right now, my go-to charger is the Q6AC.
3. I use a more powerful charger at home, and a couple of smaller ones in the field. But yes it’s possible to use one to cover everything as long as you have a mean to power the charger.

baba66 10th April 2024 - 4:54 pm

May I ask if there is any lipo charger that has temperature sensor and bloat detection designed for stopping a lipo charge job and making an alarm noise? My old Turnigy accucell 8150 has a temperature sensor that seems to be only for NiMH.

Oscar 10th April 2024 - 5:51 pm

For the LiPo chargers I’ve reviewed so far none of them have temperature sensors that monitors the batteries.

qayyum fpv 19th December 2023 - 6:23 am

what is the most acceptable balance current rating. the higher the rating the fasting the charge done but also increase the price for higher balance current rating. So what is the minimum balance current rating that consider as acceptable VS price?

Wolfgang 11th December 2023 - 8:01 pm

so many chargers and just one missing cause the SkyRC B6Neo seems to have quality issues if one youtuber can show 5 of these and 4 with a damage, mostly different failures.

What about the isdt 608 pd, not the previous ac one ?
There are no reviews out about this pd and xt60 dc charger and I am about buying one after I found out about the skyrc issues cause I asked the yter about the current state and the support he had gotten from skyrc. No reply from Sky RC means that I will not buy a product from skyrc again even though my first one from 2007 or 2008 is still working.

Hope you can put more light into this new charger.

Oscar 12th December 2023 - 9:56 am

That’s the thing about reviewing. You can only speak for the one or two units you tested, and mine has been working flawlessly.
I haven’t tested the iSDT 608 PD, maybe I will when I return home from travelling.

lalo 31st July 2023 - 10:19 am

I do have a couple batteries in which the voltage of the first cell is not showing up, and appears as blank. I am about to buy a charger. According to this article, I was wondering if I should look for a charger that offers Trickle Charging, so maybe i can revive them, I am not sure if that is a common feature.

Krotow 12th April 2023 - 10:43 pm

When you describe chargers, please ALWAYS include balance current (eq. supported current between separate battery cells during charging). This parameter is mandatory for learning how fast battery charging with particular charger will finish. Your mentioned HOTA S6 and HOTA D6 Pro (known also as ETHIX D6 PRO) are one of the best hobby chargers also due to 1.6A (1600 mAh) balance current.

Why it matter? I have SkyRC D100 charger with 200 mAh balance current and HOTA D6 Pro with 1600 mAh balance current. Moderately used 6S 1300 mAh battery with D100 charger on 2C charges around 50 minutes with almost 30 minutes spent on balancing. With HOTA D6 Pro charger same finishes below 25 minutes. Larger balance current save your time.

Oscar 12th April 2023 - 11:33 pm

Very good point, I have been pointing out the importance of balance current in chargers in my previous reviews, and that should be included in the buyer’s guide too. Thank you for the comment.

dafunk fpv 12th April 2023 - 4:47 am

balance charge… “you’ll likely spend most of your charging time using it.”
It would be a great addition if you would include the balance charge amperage of your recommended products.
My q6 takes forever to finish charging and it’s the number 2 characteristic I would look for after power supply.

Thanks for the update.

“Hi Oscar”

I was looking for something like this…I found it quiet interesting, hopefully you will keep posting such blogs….

Chris Barth 16th December 2015 - 10:25 pm

Hi Oscar, keep up the good work! I’ve watched your site grow over the last couple of years. It’s a great source of info for the hobby.
What I use for a power supply is a server power supply. You can buy one for $20 on Ebay that will give you 80A at 13V! Some will even supply more. They can also be run in series to give 24V. That’s probably overkill for quad batteries though.
They need a modification which basically consists of soldering a jumper, you don’t even need to take the case off. There are guides on RC groups on how to do it.
Trust me, if you have the ability to figure out how to get a quad up and running on your own, you can easily mod the power supply.
IMO, buying one of the expensive power supplies sold specifically for Lipo chargers is a waste unless you don’t have the skill, don’t have the time, or have extra money to waste.

Magma6 1st September 2015 - 10:42 am

Hi Oscar
Something I rarely see mentioned about why RC chargers generally come without power supply, and which always feel quite obvious to me, remembering my late teen going to the electric RC-cars race field with a buddy of mine: after each race, we plugged the empty battery to the RC charger (the big one, which can do a full charge of your NiMh battery in 15min). No power line there: the only available and practical source of power was one or two full-size car battery he kept in his car trunk. These are heavy but they can give an awful lot of amps in a short time. If you are careful about not discharging it, you can even use your own car battery.

I did not check but I guess all these chargers can run on 12-13V

Oscar 1st September 2015 - 11:52 am

yes you are right :)
actually that’s how we charge on the field, with car batteries :)
we even tried some huge 3S 10000mah lipo to supply power to the charger and charge smaller lipos :D

Asad Faruque 3rd June 2015 - 3:40 am

W have a lithium polymer battery of 32s1p configuration with Vmax 134V.
We have a BMS to monitor the cells voltage and temperature continously.
What can be the maximum charger voltage i can use to charge the above battery pack? Can we use a 180V charger to charge a 134V battery or we have to use a charger of 140V?

Oscar 5th June 2015 - 1:43 pm

Hi, you are asking the wrong person :) I don’t do 32 cell lipo :)

Hello Oscar. Many thaks for your input, im starting this jouney and you and Joshua help a lot.
I have question about hota d6 pro. I understand I do not need Voltage Checker as it has aleady inside? And iSDT 608AC do not have this option to check voltages ? Trying to understand if really need to buy Voltage Checker. And also trying to understand haw dangerous are lipo battery? Its really needed to have ammo box and store it and charge there? I have flat not home and after today research im afraid if this is for me:D
