This battery charger allows you to easily connect three 18650 battery cells to create a rechargeable battery. It features advanced design, excellent construction, and a compact size, while supporting protections against overcharging, over-discharging, overcurrent, and short circuit. When three 18650 batteries or lithium polymer batteries are connected in series, the maximum instantaneous current can reach 10A.

The 18650 battery is the oldest yet most commonly used type of battery. For safety reasons, if you want to use 18650 lithium batteries for an extended period, the use of this protective battery module is highly recommended.

This module significantly enhances the lifespan and ensures the safety of the 18650 battery. It is suitable for electronic engineers and manufacturers who use it in batteries for electronic products, such as solar lamp batteries and uninterruptible power supplies.
