The charger can do more than just analyzing motor and servo functions. The charger coupled with the "Charge Master" software can analyze your battery pack while charging or discharging. This is all done through your computer. I'm able to use the "Charge Master" and control the charger though my computer and watch realtime graphing of the battery being charged. However, there's one odd thing about it all. There's no "Charge Master" software to download from the G-Force website. I ended up downloading SkyRC charge master software and works perfectly fine with the G6P.
