4S 40A (Lifepo4) Lithium Iron phosphate Battery Protection Board

The 4 Series 40A 18650 Lithium Battery Protection Board 14.8V with Balance for Drill Motor Lipo Cell Module has an integrated 10-low load resistance MOS tube and a recovery function called AUTO Recovery.It offers a steady discharge of 40A, 100mA balanced current for low-power inverters, LED lights, and electric drills and sprayers. (Reduce load current usage if the cooling environment is poor.)The nominal voltage range for lithium batteries (including 18650, 26650, and polymer lithium batteries) is 3.6V and 3.7V, and the charging voltage ranges from 16.8V to 18.1V. The board functions without a hitch with a continuous charge current of up to 20A. The balanced version works for beginning current under 80A and power below the drill of 135W. (with balance).The Board which can be easily installed in a compact size or on the battery bundle itself.
