18650 4s BMS 40A Li-Ion Lithium Battery Charger PCB BMS Protection Board

4s BMS 4 Series 40A 18650 Lithium Battery Protection Board 14.8V 16.8V with Balance for Drill Motor Lipo Cell Module comes with recovery function AUTO Recovery and Integrated 10 low load resistance MOS tube. It provides a continuous discharge of 40A, 100mA balanced current, for electric drill/sprayer/LED lights/low power inverter. (If the cooling environment is not good, please reduce the load current use). The Scope of Nominal voltage of 3.6V, 3.7V lithium battery (including 18650, 26650, a polymer lithium battery) where Charging voltage can be range between 16.8V to 18.1V The board operates smoothly with Continuous charge current of (upper limit): 20A. The balanced version is suitable for starting current below 80A, power 135W below the drill (with balance). The Board can be easily installed in a compact size or on the battery bundle itself.
