Note:

Product images are for illustration purposes only. Actual battery dimensions, connector type, wire length, labeling, and protection circuit configuration may vary depending on the manufacturing batch. The 3.7V 400mAh 1S LiPo Battery should be charged only with a compatible LiPo charger or charging module designed for single-cell (1S) lithium batteries. Do not overcharge, over-discharge, short-circuit, puncture, crush, or expose the battery to excessive heat or fire. For safe operation and extended battery life, use an appropriate battery protection circuit (PCM/BMS) if one is not already integrated.
