About the 1S-Li-Ion battery protection hardware design PCB

1S-Li-Ion battery protection hardware design is an open source PCB design by SolderedElectronics, published on GitHub under the TAPR-OHL-1.0 license. It is a 2-layer board measuring 22 × 22 mm, with 14 components from 12 distinct parts.

Other key parts include the DW01+G(SOT23-6) and FS8205A. By type, the board carries 4 relays, 3 resistors, 2 ICs, 1 jumper, 1 diode and 1 capacitor.

It belongs with the power & battery designs in this gallery.

From the project

Hardware design, BOM, gerbers and 3D files for 1S-Li-Ion-battery-protection designed by Soldered Electronics.

A battery protector is, simply put, a device that makes sure that something bad doesn’t happen to the battery. This small circuit board protects your lithium battery (of any capacity) from overcharge, overdischarge, overcurrent and short circuit. It has a JST connector for connecting the battery, and the battery can be directly soldered.

This repository contains all design files for 1S Li-Ion battery protection, organized as follows:
