electrolight Li-ion Battery 18650 Charger Protection Board PCB 14.8v 4 Cell. Multipurpose Controller

Description: This product is 4 series 3.7V lithium battery protection board.Large current protection board, continuous 30A current battery protection panel for the integrated circuit board that can be used for the protection of rechargeable (generally referred to as lithium batteries).The lithium battery (rechargeable) is required to be protected by its own characteristics.Materials due to the lithium battery itself determines that it can't be overcharge, discharge, over current, short circuit and ultra high temperature charge and discharge, so the lithium lithium battery components will always follow a belt sampling resistance protection board and a piece of current protecting device. Specifications: Over charge detection voltage: 4.28+ 0.05 V Over charging voltage: 4.095-4.195V Over discharge voltage: 2.55±0.08 Over charge detection delay time 0.1s Temperature range -30?~80? Short circuit detection delay time: 100ms Over current detection delay time: 500 ms Balanced current: 60mA Working current: 30A Over current: 60A Short circuit protection function: there is, disconnect the load can be self recovery. Size:45x56mm Main function: Over charge protection, over discharge protection function, short circuit protection function, over current protection function, band balance. Interface definition: Charging port of the plate and the discharge port is the same, both positive and B- connecting battery"-", P- charging port and port on the negative electrode; B-, N-, P- pads are all over the hole, the hole diameter of the pad is 3.5mm; The battery charging detection interface with DC output in the form of needle. Do the same mouth when the N- is not wiring.
