How to charge a lithium ion battery?
However, even with this protection, it is very important that you only use a LiIon/LiPoly constant-voltage/constant-current charger to recharge them and at a rate of 0.5C (2.2A) or less. Like most lithium-ion packs, the batteries we sell do not have thermistors built-in. This is why we suggest charging at 0.25C or even less - 1A max in this case.
