18V21V Power Tool Lithium Battery Protection Board OLT-MT5S90A

This product uses a 5-cell lithium battery-specific IC as a processor to detect each battery's voltage, charge and discharge current, and ambient temperature in real time.
Realize battery overcharge, over discharge, discharge overcurrent and other protection functions;
It has protection functions such as short circuit, over-current and temperature protection;
The circuit board is of good quality, and the copper hardware and thickened terminals are durable;
It does not generate heat during long-term use and is commonly used in for Makita lithium-electric angle grinder battery packs.
