Ouch! battery got so hot it melted the shrink wrap!!!
#1
My temp gun reported 213* in some spots with an average reading of about 195*!!!!

Damned hot, way too hot. The motor is only reporting 138* which is about right.

This is a Novak 4.5R brushless system in a Tamiya F201 F1 car. The batteries are Epic dreadnaught 3,000mah packs i had from previous cars using Deans Ultra plugs. After the run the leads and connectors are only mildly warm to the touch, the real heat is found in the cells themselves.

Why are the cells heating up so much? I don't remember them heating up this much when I was running them in my Losi XXX-T w a 5.5R system.

Advice is much appreciated right now.

BTW, its pretty quick, but not quite the top speed or acceloration i was expecting. Gearings too tall which is probably leading into the packs running so hot, but my adjustable motor mount hasn't arrived yet so I can't throw a different pinion on the motor.
