LaskaKit LiPol Battery 805080 4000mAh 3.7V JST-PH 2.0

Product detailed description

The Lithium polymer (Li-Pol) battery 805080 with a capacity of 4000mAh is a slim, lightweight, and powerful accumulator with a nominal voltage of 3.7V (4.2V when fully charged). The energy capacity is approximately 14.8Wh. The battery is equipped with a protection circuit against overcharging, over-discharging, and short circuits.

The battery includes a protection circuit that maintains the battery's voltage so it is not too high (overcharging) or too low (over-discharging), meaning the battery will be disconnected once discharged to 3.0V. This circuit also protects the battery from short circuits. However, even with this protection, it is very important that you only use a LiIon / LiPoly CV/CC charger. We recommend using our TP4056 Li-ion cell charger and setting the required current with a jumper.

If you need larger (or smaller) batteries, we have a whole range of LiPoly batteries
