Description

AA-JA11113 is a battery balance and protection board designed for 3pcs 18650 Lithium batteries in series, featuring full protection and high reliability, which improves the portability of the whole audio system and is a perfect rechargeable power supply solution for portable speakers. When fully charged, this battery board can provide 12.6V output voltage. With full awareness of the importance of operation safety, we employ overcharge, over-discharge, discharge overcurrent, short circuit, charge overcurrent and over-temperature protections in this battery board. The protection circuit will keep constantly monitoring the voltage and current of each cell. In addition, the Lithium-ion battery balance and protection extension board provides external bleeding for cell-capacity balance function to avoid unbalanced capacity between each cell.

Please note that charging circuit is not equipped in this battery board. If you want to recharge the batteries, make sure you have a JAB1 / JAB2 at hand as they are equipped with MPPT charging circuit.

I would like to use this with the 1 x 100 Watt Class D Audio Amplifier Board w DSP - JAB3-1100[724] and the Bluetooth Audio Receiver Board V4.0 with Control Panel - BRB6P[701] , would that be possible?

Hi, jak. Thank you for your interest in our products. Please kindly be noted that the charging circuit is not equipped in this 3S 18650 battery board (JAB accessories). It's employed in JAB2. Therefore, if you want to charge the batteries, JAB2 would be requisite. If you want to power JAB3-1100 and BRB6P, we recommend you to buy BCPB2, 3S 18650 battery board integrated with charging circuit. Since the output voltage depends on the battery capacity, its maximum output voltage is 12.6V when fully charged, under which condition, the output power of JAB3-1100 will be lower. http://store.sure-electronics.com/product/PS-BC12111 Wish this could help you.

Hello, can this product be daisy-chained to extend battery capacity? I plan to use ist with JAB2: 1 X 100 WATT CLASS D AUDIO AMPLIFIER BOARD WITH BLUETOOTH - JAB2 - 1100[743]

Hello, Yannic. Thank you for your interest in our products. Please kindly be noted that all the WONDOM battery charging board cannot be connected with each other. If you want lager battery capacity, we recommend you the BCPB3 (5S 18650 battery charging board) or BCPB4.(5S 26650 battery charging board). http://store.sure-electronics.com/product/PS-BC12112 http://store.sure-electronics.com/product/PS-BC12113 Wish this could help you.

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.
