Description

The 3S 18650 Lithium battery charger and balance protection board is a charging and protection module for 3 pcs Lithium batteries pack. It is highly integrated and can be used as portable power bank.

With MPPT charging ICs equipped, this board works as charger and supports 15-24V power supply for charging. Four indicators are equipped as battery status reminder.

The Lithium battery charger and balance protection board works constantly to monitor each cell’s voltage, the current of charge or discharge, and the temperature of the environment to provide overcharge, over-discharge, overcurrent and over-temperature protections, etc.

The battery charger and balance protection board is designed for 3 pcs 18650 Lithium batteries in series, which aren’t included in the package. You need to prepare the Lithium-ion batteries with 3.6V typical working voltage and 4.2V overcharge protection voltage. Besides, any other batteries especially LiFePO4 battery are prohibited.

Hi ! Can we charge the18650 of an AA-JA11113? Just to be sure.

Hi, Chris. Thank you for your interest in our products. Please kindly be noted that for charging AA-JA11113, the charging circuit is integrated in JAB2, which means if you want to charge 18650 batteries with AA-JA11113, JAB2 is requisite. BCPB2 is equipped with the charging circuit, which can charge the batteries by connecting with a power supply within the recommended range. Wish this could help you.

Hi, Can this recharge at the same time as it is supplying power to an amplifier board? Cheers, Andreas

Hi, Andreas. Yes, all boards in WONDOM BCPB series (BCPB1-4) are able to charge and discharge at the same time. Wish this could help you.

Hello, Just received the board - very happy! Please could you provide exact pin information for J17, J18 and J19. Is it possible to connect LEDs directly or are resistors also needed? Thanks, John

Hello, John. Thank you for your support of our product. The detail pin information of J17, J18 and J19 has been attached for your reference. Please kindly be noticed that resistors are required to be connected with the external LED indicators in series and the suggested resistance is 680Ohm. Wish this could help you.

The connection diagram is for an amplifier board, not this product. Can you fix it?

Dear Er.Sp, thank you for your feedback. We have changed the connection diagram of BCPB2. It is customers like you who make WONDOM better. Please feel free to contact us if there is any other problem.
