4S 30A 14.8V Li-ion Lithium Battery Protection Board Battery Equalizer Board

Feature: *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 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. Specifications: Product Name: Battery Protection Board Color: Red 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 10A add heat sink 15A the maximum instantaneous current 30A) Remove protection condition automatic recovery without activatio 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 Quantity: 1pc Package Included: 1 × Protection Board Note: 1.Transition: 1cm=10mm=0.39inch. 2.
