QCCAN 3pcs 5S 15A 18V 21V Lithium Battery Protection Board, 18650 Charger Cell PCB BMS Protection Board Module for Li-ion Battery Cell Pack with Cable($11.99Value)

Description

High Quality, High-accuracy voltage detection circuit, fine workmanship and durable, equipped with battery core balancing function,low standby current, low power consumption. Applications: It is used for 5 series 3.7V Li-ion batteries, massager battery pack, LED light backup power supply, solar street light battery pack, monitor standby power supply and so on. Multiple Protection (Short circuit/Over-current/overcharge/Over-discharge): After disconnecting load will auto recovery. Notice:Please strictly according to the diagram wiring to avoid possible damage to the chip.(Connect wires refer to the "wiring diagram"(NO.5 picture). After connection, it need to charge activation first, then will have the output. Package includes:3 x 5S 15A Lithium Battery Protection Board+3 x Wire
