70A High Power BMS Discharge Protection PCB Board For 18V/20V MAX Lithium-Ion Battery Packs

Building or repairing a power tool battery pack?

This is the brain you need.

It's a high-power 70A BMS (Battery Management System) PCB designed specifically for 18V or 20V MAX lithium-ion battery packs.

This is for the discharge protection, keeping your cells safe from over-current, short circuits, and other issues.

Please note: this is just the circuit board—no batteries are included.

It's an unbranded board, but it's built to handle serious current.

If you're rebuilding a pack or creating a custom battery solution for a project, this is a critical component to do it safely.

It's black, compact, and designed to handle the high draw of power tools.

Make sure you know your way around Li-ion cells before tackling this project.
