Description
As the new comer of BCPB (Battery Charging and Protection Board) series, BCPB4 inherits the high efficiency and high reliability of BCPB2, offering more battery holders and larger capacity. BCPB4 is designed for 5pieces 26650 Lithium Batteries in series and can be used as a power bank for Routers, Raspberry Pi, High power portable speakers and Mobile phones, which is widely used in Home DIY applications to save your precious time from the connection of electric wires. Supporting wide range of charging input voltage and hybrid charging sources is one of the highlights of BCPB4. Any 5-24V 2A adapters can be used to charge the batteries with BCPB4.
This board can be powered by multiple chemical components of rechargeable batteries like Lithium-ion battery, Lithium-iron phosphate battery, Ni-MH battery, Li-Fe-Po battery and Lead-acid battery. Besides that, the balance and protection circuit constantly to monitor each cell’s voltage, the current of charging or discharging, and the temperature of the environment to provide overcharge, over-discharge, output over-current, short circuit, charge over-current and over-temperature protections, etc.
