Description

The Lithium-ion battery balance and protection extension board is a protection module for rechargeable battery pack; it is highly

integrated, and specially used for WONDOM’s audio amplifier boards. The Lithium-ion battery balance and protection extension 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, discharge overcurrent, short circuit, charge overcurrent and over-temperature protections, etc. The Lithium-ion battery balance and protection extension board provides external bleeding for cell-capacity balance function to avoid

unbalanced capacity between each cell. Thus, the batteries can work for longer.

I purchased JAB 2 (50w) board and the battery balance board recently. When connected together, the battery board (aa-ja11113)does not power the amplifier board or charge the batteries. How do I troubleshoot this? The amplifier board works when connected to an external DC 12V power supply. Could it be a faulty battery board that I received from you? Thanks, PF

Hi, Prince.Fonseka. The new battery board need to be activated. Please connect the battery board with JAB2-250 and connect the JAB2-250 with a 15-24V power supply to activate the battery board. Wish this could help you. If there is any problem, feel free to contact us with store@sure-electronics.com.
