Hi guys, Im new to electric. I picked up an Impulse Power 3 cell 11.1 950 mahlipo from hobbypeople and i plugged it in for its first charge, and within a few seconds te charger gav the finish charging tone and so I plugged in to the receiver and got no servo control or anything, took it off and checked the voltage and it had lke 2.5 volts at the connector. The warranty says it wont cover under voltalge batteries. Im not sure if the store will take it back? Any fixes for this?
