Add to wish list

The FIT0869 is a battery charger that allows you to easily gang three 18650 battery cells together to create a rechargeable battery pack.

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

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