Same issue with a 300C

Had the same issue with a GWS 300C-C, Pixie 7p with 2s Kokam 1500 HD. Either a 10X4.7 or 9.7 would engage the cutoff at 3/4 throttle with a fresh charge. Programmed the Pixie to the soft cutoff mode and it works fine now, but I prefer the hard cutoff.

I still dont understand why the motor would drag the pack down to under 3volts/cell, the batteries are new (less than 10 charges on it) and the motor was broken in.

Only thing that I can think of that might be a problem is the JST connectors. I attached them to the Pixie with nice solder joints, so hopefully that isnt the problem. Could be the leads are too long?

Anyone know the best way to check the power from the batteries under load with a standard multimeter? Im not an electronics expert, and dont have the money currently for a Whattmeter.

Thanks....
