The protection board can be used as a nominal voltage of 10.8V, 11.1,12.6V four string polymer lithium battery pack, four 18650 lithium battery pack as overcharge, over discharge, short circuit protection. No activation is required. For applications with high instantaneous currents, inverting applications can protect against false triggering and are easier to use.
original protection chip, the United States imported 70A high-current low-resistance MOS tube, heat smaller. Large pad output, wiring more firmly.
Back no part design, can be attached to the heat sink, high current conditions, long time guarantee.
