UL-1 Batteries

[marks]

What are the maximum power batteries that I can use in a stock UL-1, without burning up the ESC (60A) and motor. the manual calls for 2S 7.4V 3200mAh 20C = 64 useable amps.
Will the Grim Racer 2S 7.4V 4200mAh 30C be too much ?? Also any input on the Venom ac/dc pro charger plus peak/balancer ?? any good ?? Kind of new at this. Thank you.

I've used a 3cell and a 2 cell pack with no problems. Never 6 though, that might blow the esc...

Not even close buddy. I use sky 2s 5000mah 40c. The bigger the mah and c rating the better

The esc amp draw is related to the motor. The motor pulls the amps and determines the size esc you need. You can't kill the esc by having your batteries provide more then enough amps, however you can kill your esc if your batts can't supply enough amps. The more amps your batts can supply the better for the system. You can kill an esc by over-voltage as well.

Those will work fine. With reasonable amp draw (not enough to smoke the motor or ESC) you don't need 45C/5000 mAh packs. Cell quality is more important at this level than ratings.

Venom does not have a very good reputation among FE boaters.
