18650 lithium battery protection board

Overview

18650 protection board
6-cell 18650 lithium battery
outputs 24V
with short-circuit protection, over-current protection, and low-voltage protection.
The project is all open source
and no code is required. All hardware components
are applied to T12 electric soldering iron and C245 electric soldering iron power supply.
The engineering documents are as follows:

April 24, 2023 Update: The standardization of wiring has been improved, the battery hole has been enlarged, and it is more stable.
