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.

With MPPT charging circuit equipped, this board works as MPPT solar charge controller and supports up to 35W charging ability. 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.

Would you consider in the future to make this unit compatible with 18650 batteries as they are more readily available?

Hi, Syd. The product you mentioned (5S 18650 Lithium Battery Charging, Balance and Protection Board) is in our plan and it will be released soon. Please stay tuned and thank you for your support.

Can this be used to power the JAB1 and JAB3 simultaneously?

Hi, William. The BCPB4 provides multiple discharging ports so it can power JAB1 and JAB3 at the same time. But please be noted that JAB3 cannot be connected with JAB1. Feel free to contact us if you have any problem.

Can you chain these boards to increase capacity like the 3S model?

Hi William. Please be noted that the 5S 26650 Lithium Battery Charging, Balance and Protection Board-BCPB4 cannot be connected with another one for safety.

What is the voltage output of this board 12 or 24. Looking for 24v.

Dear James, Sorry for the late reply. When the batteries are fully charged, the output voltage of BCPB4 can be up to 21V.
