I have a 37v 10 Amp hr Lithium Ion Polymer battery that has been sitting around unused for 12 months. I am not sure if the charger is able to charge due to the battery being over discharged. I measure 44 volts from the battery before turning the throttle on the bike. If I sit on the bike the power dies almost immediately. I then measure the battery voltage at 2.5 volts. If I then put the battery back on charge the charge light does not come on instead the green led light is illuminated suggesting that the battery is fully charged. I can then measure 44 volts from the battery again.
Is my battery recoverable? I understand that some batteries have inbuilt protection to prevent you from charging batteries that have been overdischarged. I don't have a balance charger but would using one and charging in NiMH mode be able to increase the voltage high enough so that I can resume normal charging again. I have seen some youtube videos showing how overdischarged batteries are recovered by charging in NiMH mode.
