I have a HW903475 7.4V (2S) lithium battery. It has a three pin connector for the charger so I guess that the charge balancing is done by the charger but do I need to provide overdischarge protection or is it built in to the battery pack.
I could connect a resistor and monitor the voltage but if it doesn't switch itself off, how low can I allow the voltage to get before any damage is done, but low enough to have triggered the battery protection circuit if it has one.
Any better way of doing this?
