4S 30A High Current Li-ion Lithium Battery 18650 Charger Protection Board Module 14.4V 14.8V 16.8V Overcharge Module for Arduino

Condition:New Operating Temperature:-40 ~ 85 Celsius Dissipation Power:none Type:Voltage Regulator is_customized:Yes Supply Voltage:as details Application:Electronic Circuit Overcurrent:20-30A The module name:4 string lithium battery protection board The modular nature:polymer lithium battery protection board Description: Over discharge detection voltage: 2.50 ± 0.08V Over discharge termination voltage: 3 ± 0.1V Overcurrent: 20-30A Working current: 15A (natural cooling:10A, plus the 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. Buyers show Unit Type:piece Package Weight:0.01kg (0.02lb.)
