the motor speed is in Kv if a motor is for instance 2300Kv

that means 2300 rpm per volt

if ya have a 2300kv motor and stick it to a 7.2 battery

you do 2300 X 7.2 = 16560 rpm

IMAX B6 will charge most batteries. I find them excellent value as they will charge all Lipos, Nimahs, Nicads, Lead Acids, even the new LiFe batteries.
