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
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?
