Polymer Battery Description:

The 500mAh lithium battery includes positive, negative, separator, positive tab, negative tab and insulated mat. After cells are finished, we will add connector to electricity out. It can be JST, PH, Molex or others. It supports 500 cycles and remains 80% capacity.

Another key component is protection board, also named PCM. It contains IC chip and Moseft to ensure performance well. It is applied to the protection of lithium-ion battery from overcharge、over discharge over current and short-circuit. Below is electricity parameters for your reference:

Overcharge detection voltage
Overcharge detection delay time
Overcharge release voltage
Over-discharge detection voltage
Over-discharge detection delay time
Over-discharge release voltage
Operation of current consumption
Over-discharge current detection
Over-discharge current detection delay time
Short-circuiting detection delay time

Lithium polymer battery advantages:
