The iMAX B4 Compact Balance Charger makes charging of your Lipoly batteries easier than ever before. With no current limits or cell counts to set, you simply connect your battery to the B4 and it starts charging automatically. The charge current is variable, determined by the capacity and charge state of your battery. The max charging current is 4A (up to 35W).
The B4 comes with everything you need including charge lead and alligator clips for connecting to a DC power source.
Features: • Simple to use • Compact size • Automatic charging of 2~4S batteries • Up to 4A (max 35W) charge rates
Specs: Operating Voltage: 11~18V DC Charge Power: 35W max Charge Current: 4A max; Charging process will monitor battery capacity continually and adjust charge current as necessary. Balancing Current: 200mA/cell Lipoly Cell Count: 2~4 cell (7.4V~14.8V) Dimensions: 100x63x34mm
My test shows that it changes a 3s 35c 2200mAh battery at only 1.2A (so about 2 hours to charge).
I would not recommend this charger for any thing. Better to get the HobbyKing ECO6 50W 5A Balancer/Charger which is good.
i got this one with the hope that it will charge faster than the other model... Not at all..it hangs about 3-4 hours to charge a 2200 mah 3s lipo (new lipo) Charging current is far under 4 Amps..i do not know how it controls the process automaticly, but each time charges 3-4 hours (1500 mah - 2200 mah 3s lipos, tried it on few batteries)
Hi Nukii. I just received one, and I think I am having the same problem. I tried charging a 1000maH battery, measured the approximate charge current of 0.8amps, it seemed to charge it after about 50 minutes, but then spent 1 hour trying to balance, I stopped it after waiting this long. I then tried a 2200maH battery and measured 1.1amps charge current, I gave it 15mins but it just stayed at 1.1amp. Could be a complete waste of money. Did you get a replacement?
Good product,, accurate voltage and safe.. thank you hobbyking

I bought 1 of these chargers and it did not work. I tried to charge a 3S 1000mah battery, it would charge it, but LEDs did not go orange when 90pcnt full as stated in manual, and then once battery was charged to 12.6v it stayed in balance mode for 40mins (1hr 45mins after starting charge), after this much time I turned it off. HK then sent me a replacement and the replacement charged 20pcnt faster but had the same faults. Both chargers going in the bin.
