Product Description

STYLE:

5 series lithium battery protection board 18650 lithium ion battery circuit board module XL-MH9955 power tool 21V

Feature:

1. Adopting mature 5 series dedicated lithium battery protection chip for central control, featuring high integration and high sensitivity.
2. By detecting the charge and discharge current, voltage and ambient temperature of each battery, it can realize the protection of overcharge, over discharge, discharge over current, short circuit, charge over current, temperature and other real-time protection.
3. The adjustment of the parameters can also be realized by an external circuit.
4. Widely used on battery packs for power tools using 18650 lithium batteries.
5. High-quality electronic components ensure the stable and reliable performance of the lithium battery protection board.
