This battery charger allows you to easily gang three 18650 battery cells together to create a rechargeable battery pack.

Featuring sophisticated design, fine workmanship, and small size, the board supports overcharge, over discharge, overcurrent, and short circuit protections.

When three 18650 batteries or polymer lithium batteries are combined in series, the maximum instantaneous current can reach 10A.

As a very important invention in history, the emergence of batteries has indeed solved many problems, and the 18650 battery is the oldest but commonly seen Type.

However, 18650 Battery burning or explosion happens when it’s charging and discharging. For the sake of safety, if you want to use 18650 lithium batteries for a long period, this battery protection module is highly recommended.

The module greatly enhances the service life and ensures the security of 18650 battery pack.

It is suitable for electronic engineers and makers to use in solar street lamp battery packs, monitoring backup power supplies and other electronic products.
