Power output is limited by the internal power supply, where you can only use 50W for each channel (or 200W in total). So I decided to test it with some external power supply so I can use the charger at its specified power (in total 300W).

I tried two different power supplies: a PC power supply rated at 400W/14A, and a server power supply rated at 32A max.

The biggest issue i had was the voltage sag between the power supply and charger. When the charger is under load (charging), I measure the voltage at the PSU output with my multimeter, and voltage input displayed on the charger screen.

With the PC PSU, I used four cables soldered in parallel to connect the charger with the PSU, but I still had 1V voltage drop at 12A load. With the server supply I had to use a normal quadcopter 12AWG silicone cable, and I could use the specified power of the charger. When I used the charger under its full load, It drew approximately 28A from the power supply.

I was having a 0.5V voltage drop on the cable (measured 12V at PSU output, 11.5V at the input of the charger). However the charger displayed 11V as the input voltage for some reason, so maybe there is another 0.5V drop from the input connector to the voltage measurement circuit, or it’s simply a display error? I am not sure why, but I had to set the minimum voltage limit on Q200 to 10.5V, means that in this case at the input connector there will be 11V.


  • 4 channels are very effective and powerful for racer class batteries. Much more useful than a one channel >20A charger. It allows you to charge 4 separate batteries simultaneously and not use a parallel board (which I don’t recommend doing for 1. non equal discharge levels, 2. different internal resistance, 3. longer balancing period)
  • The included android / iOS application (connected via Bluetooth) is useful, convenient if you do not like pushing buttons, or cannot control the charging process (when you do not see the display itself)
  • It gives you the specified charging power, that is more than enough :)


  • Very good product, but it is “chinese” product. Nothing is 100%, not well matured
  • It is not an integrated four channel charger, it is four, one channel charger
  • There is no need 40 memories, 4 * 10 independent. One 10 stock would be enough
  • There is no reason why I have to program the channel memories independently (for the same programs)
  • Charger Bluetooth module is weak, the smart application can be used only within 1-2m
  • A little bit too large, and can be noisy. Very loud while discharging / running storage process.

PC Program: Q200

The PC interface could be a very good software, but it needs a bit more work IMO: bit more polishing to and development to make it a truly handy tool.


  • Easy to configure the channels with a few mouse clicks, and working on the big Laptop / PC screen is always more comfortable than a small LCD display on the charger
  • You can create one program, and load it for all of your channels.
  • There are charts about the charging processes (voltage and current), so you can compare your batteries easily
  • Common memory slots for charging programs, can be use for all channels.
  • “One push” control if you repeat the same charging process.


  • After you connect your PC with Q200, you cannot switch off the charger by removing the DC in, or switch off the internal power supply. Although only the display is powered on and the charger isn’t actually functional, you cannot switch the charger back on again before removing the USB connection, then plugin the charger power. This means, that the USB connection actually powers the charger backwards
  • Memory storage is useless as the program forgets the programmed slots after exiting
  • The Q200 desktop application is not a complete product
    • It cannot control a charging process that was not started from the program
    • It loses the memory programs after exits

Android / IOS app

SkyRC created a very handy application to control the charger via its internal Bluetooth module. It is beautiful, and almost ready IMO.


  • Easy to check the current charging process
  • Very easy to start charging on all of the channels if the process parameters are the same (in most cases we use the same type battery while racing, so we need the same program on each channel)
  • The App is much better than using the push buttons on the charger (I often get confused with the channel buttons, so I sometimes stop a wrong channel, or set a wrong parameter, etc)


  • I couldn’t understand why they put the barcode function into it.
  • Changing channels loads very slowly
  • There is no need for independent programs for each channel. One common bank would be enough
  • There is no chart / graph about the process

This charger has serious problems with Pb and Nicd batteries, especially when they are well discharged. I am not able to charge the Pb batteries of my lawnmover or the NiCd battery of my electric drill. After starting the charging, almost immediately the error message “no battery connected” appears on the display. Obviously, the battery check procedere is way too fast and/or inacurate. Abolutely no problem to charge this batteries with my good old Graupner Ultramat 16 or with the Absima Duo Touch charger. Contacted the support, but they did not answer.

Do you recommend to buy it? Or it’s better to buy 4 DC Lipo Chargers in BG or HK?

I have this charger. Had the D100 and D50s previously b They all seem to have the same basic operation. I like them. I’ve had them open and they are pretty well constructed (not obviously built to a price point)

I believe the barcode is to allow for quick setting of charger parameters. Stick a barcode on your battery, scan it, and the charger is ready to go. (I need to try this.)
