I really like iSDT chargers, but they didn’t come with a power supply and so often beginners were unsure as to what to get. Finally iSDT released the new 608AC charger that comes with a PSU, and it’s in a very portable form factor too.
Where to Buy?
The iSDT 608AC LiPo charger is available from the following vendors:
- AliExpress: https://s.click.aliexpress.com/e/_DeFsS2f
- Banggood: http://bit.ly/isdt-608ac
- Amazon: https://amzn.to/38YgRuY
- GetFPV: http://bit.ly/2Sf4Hax
- RaceDayQuad: http://bit.ly/390muJ1
In the box it comes with
- the charger + PSU
- power cable
- anti-slip foam tape
- iSDT stickers
What’s special about the 608AC?
My personal go-to LiPo charger has been the iSDT Q6 Pro, mainly because of its reliability and portability. However, in order to make it so small, power supply (PSU) is not included and so users have to buy the PSU separately.
Here is a beginner guide explaining the basics of LiPo chargers and power supply.
That’s why I think the latest iSDT 608AC might be a better first LiPo charger for beginners thanks to the included PSU. Including the PSU, the charger only weighs 350g, with dimension of 110.5×110.5x31mm.
What’s even better is that the PSU is removable, allowing the 608AC to take both AC and DC input power, it makes travelling easier and field charging possible. Learn about the basics of field charging in this article.
Despite the lower power rating, the 608AC is slightly bigger than the Q6 Pro even without the PSU.
Specs & Features of the 608AC
Power Supply Unit
- Power 60W
- Input Voltage 100V – 240V
- Output 19V 3A DC
- Power 200W
- Input Voltage 10V – 30V
- Output Voltage 1.0V – 30V
- Charge Current 0.1A – 8.0A
- Discharge Current 0.1A – 1.0A
- Max Discharge Power 10W
You can perform all the common tasks with the 608AC charger:
- “balance charge” single battery
- parallel charging
- charge 1S, 2S, 3S, 4S, 5S, 6S LiPo
- charge LiHV (4.35V/cell)
- charge 18650 Li-Ion Cells
- discharge battery for storage
The iSDT 608AC supports LiFe, Li-ion, LiPo, LiHv 1-6S / Pb 1-12S / NiMH 1-16S. The full list of supported batteries, voltage and current are as follow:
The 608AC has a much smaller screen than the Q6.
But the interface and information displayed are almost identical. The text is smaller, but it’s perfectly readable. Perhaps I am used to the Q6, I find the 608AC interface really very simple to use.
The 608AC charger has a rolling wheel button on the side, similar to the one in the older iSDT 620 and 608 chargers. Operation is made intuitive and user-friendly by the wheel button, it allows you you to easily navigate through the menu and options.
On the front, there are the balance port and XT60 output, along with a micro USB port for firmware updates.
On the left hand side there is the AC connector and cooling fan.
The PSU is connected to the charge via a female XT60 connector.
Removing the PSU, you can power the 608AC from a DC power source between 10V to 30V (e.g. 3S to 6S LiPo).
When you use the included 60W PSU, the charger automatically sets the maximum power to 55W, and the lowest input voltage to 17V, and you cannot change it. This is clearly an excellent safety feature so you don’t overload the PSU by accident.
The full potential of 200W 608AC can be “unlocked” by powering from a DC source, e.g. a LiPo battery. You can do so by removing the PSU, and plug in a battery. Now you can now change “lowest input voltage” and “Max Input Power” freely just like a normal iSDT charger.
This is my huge 6S 10,000mAh LiPo battery for field charging, and I’d set lowest input voltage to 21.5V to avoid discharging my battery below 3.6V per cell. And set max input power to 200W just to match the power of the charger.
This is how I put the anti-slip stickers on the bottom.
Although this is a 200W charger which is good enough for most people, unfortunately the included PSU is only 60W. To put that into perspective, you can only charge a 4S LiPo (16.8V) at 3.5A. Charging a 4S 1300mAh will take under 20 minutes, while charging a 6S 1000mAh will take under 25 minutes.
The PSU is indeed a bottleneck if you want charge quicker, but I think for beginners 60W is plenty because you probably don’t have that many LiPo batteries to charge (yet). You can still parallel charge with this charger and PSU combo, but it’s not going to be very fast.
As you progress, you can simply get a more powerful PSU, and use the same charger. A decent 200W PSU for example, shouldn’t cost you more than $20. Alternatively you can also modify a server/computer PSU for your charger if you know how.
If you are new to LiPo batteries, make sure you learn about how to handle them safely to avoid damage.
I have been using the iSDT 608AC for a couple of weeks now it’s been performing reliably. With the detachable AC to DC power supply, this charger is easy to carry around, to use both indoor and outdoor.
I only wish the PSU is more powerful, it would be nice to match the power of the charger so we don’t have to upgrade in the future, but I guess that would increase the cost considerably. For $60, even with a 60W PSU this is still a pretty good deal in my opinion.
So yea, with the limitation in mind, I would recommend this charger to beginners and casual flyers. However, if you want a more powerful charger that you don’t have to upgrade for a long time, check out the D6 Pro. It also has a built-in PSU for AC power as well as accepting DC power :)
Do not update the firmware or u lose battgo and dc output
I ordered this charger and it came with that same plug you are showing in your picture. I am guessing its a European outlet plug. Can I just replace it with a 110v US power cord and be ok? The scariest thing by far for me with this hobby has been learning batteries and chargers. Thanks!
Absolutely, it’s not compatible in the UK either and I replaced it with a UK cord i found on eBay, all worked fine.. The cord itself literally is just some wires, has no electronics in it.
Hello Oscar, thanks for the review!
I own a 608AC but unfortunately I damaged the LCD. Do you know where I can purchase the spare?
Can you use this DC by just clipping it to your car battery? I would be charging in a batsafe to keep my car from catching on fire.
It takes DC input too (10V-30V) by removing the power supply module.
So it means it could be powered from car battery aka cigarette lighter?
Hi, a question about powering it off ac.
When I plug in the ac cable to my UK adapter, it won’t power on at all. UK wall socket voltage is 240v, so I dont understand why it wont turn on. Any thoughts on how to make it turn on?
Maybe a faulty PSU? try a different socket if no luck maybe contact your reseller for replacement.
PLEASE HELP! I just received the ISDT 608AC charger in the mail and attempting to charge my 1500mah 4s batteries. When I plug in the balance lead, I’m getting voltage reading on 6 cells, with the 3rd and 4th being much lower. (3.5v, 4.6v, 1.3v, 1.3v, 5.2v, 5.4v). After plugging in the main lead, only the first two cells give voltage reading (now 4.9V and 5.5V). For reference, I checked this battery on a capacity checker and it’s reading just about 3.8 V per cell, says 58% charged. I am hesitant to try and start the charging process, given the charger is identifying the 4s as 6s with only the balance lead in, and then only 2s with the balance and main lead. I am so confused and just want to get the batteries charged so I can start flying fpv.
definitely something is wrong. Double check voltage of each cell with a multimeter, if this is different from what you read on the charger, stop using that charger and contact the place where you bought it from, ask for a replacement or customer support.

not true. It can work in DC power supply mode.
Yes it is a charger but it has a “DC Power” option which makes it work as a power supply. Therefore I wonder whether can it be used as a “cheap” lab power supply for testing / repairing the quad on bench? Especially that it has a current limit so smoke stopper won’t be necessary.
I used to plug in my solder until I updated the firmware and now it no longer function. Says abnormal input power. My 2nd 608 I did not updated the firmware works fine
How does this charger work as a DC power supply? Can it be used for quad maintenance instead of lipo battery with smoke stopper?
No, it’s a charger.
Where to get battgo batteries, yet leave alone decent C rating and quality or correct pack sizes. Is that feature useless ? Looks to me ISDT made it properitary and battery companies don’t find battgo implementation cheap? Why only one brand and out of stock everywhere.
i don’t think this is picking up in the FPV industry, It probably won’t go anywhere from how it looks now.
