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.
