4 sections 18650 battery box and KF8500-8.5 terminals are integrated into a PCB board, convenient for 18650 battery installation and removal and battery positive and negative wiring, directly on the terminal with a screwdriver to tighten and loosen the wires, no need to weld the wires to the PCB board. Each 18650 battery box and terminals - corresponding and separate from each other, can be installed at the same time more than 4 18650 batteries. Flexible wiring can be performed to allow the battery pack to be connected in series and parallel, such as 4 series, 4 parallel, 3 connection series, 3 connection parallel, 2 series, 2 parallel, two parallel and then two series, two series and then two parallel. Convenient wiring with 1 series, 2 series, 3 series and 4 series lithium battery protection boards, note: the same specification is used when the batteries are connected in series and parallel, and the thickness of the wires is also the same as far as possible.
