Infraction Voltage Drop

[CARPJR]

I'm runing an Infraction. Using Two Cheap 3S 80C 5200MAH batteries in series into a Spektrum 160A ESC (out of a Kraton) into a Castle 2200kv motor.

While doing short speed runs I'm getting a cutout at wide open throttle. My data shows minimum voltage dropping to around 16 volts.

Is my cutout caused by a couple bad battery cells? Is that unusually high voltage drop?

Running 29/34 gearing - it's a very heavy load.

Or is this just too much for that ESC?

You’re probably exceeding the amp limits of that ESC. You can do a few things:

1) Gear down until it doesn’t amp limit
2) Take longer to get up to full speed
3) Swap for a lower KV motor
4) Swap to a MMX8S or XLX2
5) Higher rated lipos (100C+)

if you are getting over 50,000 rpm it might cutout
