Status: offline 		Can't give you the max rate, but I charge mine all the time at 3 amps which is max for my charger...Seem's like I read on another forum of people chargeing them at 5 amps though.  Mine have been a excellent product, I use them as RX power (2S) and motor power (4S), many cycles and zero problems in almost 2 yrs of use........
