Description
4S 30A High Current Li-ion Lithium Battery 18650 Charger Protection Board 14.4V 14.8V 16.8V BMS Overcharge Parameters: overcharge detection voltage :4.25±0.025V overcharge Lift the voltage:4.15±0.05V over discharge detection voltage :2.50±0.08V over discharge Lift the voltage:3.00±0.1V overcurrent current:20-30A working current:15A(Natural cooling 10.A, add heat sink 15A, the maximum instantaneous current 30A) Termination conditions:the release of protection condition then automatic recovery, without activation (optional charger to activate) Main functions: the overcharge protection function, overdischarge protection, short-circuit protection, over current protection. Working temperature: -40~+85 degrees (high temperature environment and please strengthen radiating) Connection: welding output Module size: 50mm*22mm*4mm Applications: The protective board can be used as the nominal voltage of 14.4V, 14.8V, 16.8V four series of polymer lithium battery group, four series of 18650 lithium batteries as overcharge and over discharge, short circuit protection. Without the activation function in the power application for high instantaneous current,and in inverter application for avoid false triggering protection.So it will use more convenient. Note:No part design on the back, can be attached to the heat sink to ensure high current work situation for a long time. Package Included: 1pcs * 4S 30A High Current Li-ion Lithium Battery 18650 Charger Protection Board
