3S 12.6V 18650 Polymer Li-ion Lithium Battery Charger Protection Board 15A Discharger and Charger BMS Balance Module Features 1. Supports 3 series-connected lithium-ion batteries, precisely matching the voltage range of 11.1-12.6V. 2. Continuously outputs a high current of 15A, meeting the needs of high-power devices. 3. Built-in charge balancing extends battery life. 4. Built-in overcharge and over-discharge protection ensures safe and reliable operation. 5. High-reliability components ensure stable operation and low temperature rise for added safety.

Product Parameters Charging voltage: 11.1-12.6V Continuous output: 15A With passive balancing function 4.25V overshoot protection (single cell) 4.15V overshoot release (single cell) 2.7V over-discharge protection (single cell) 3.0V over-discharge release (single cell) 4.1V balancing start voltage Quiescent current: 10μA Sleep current: 1μA Product Description This product is a low-power battery pack protector designed for primary protection of 3 series-connected lithium-ion/polymer rechargeable batteries with balancing. However, the balancing current is limited to just over 20mA, which is only used to eliminate errors between cells and prevent voltage differential accumulation over long-term cycling. Large differences in battery capacity cannot be compensated by this type of dynamic balancing. Professional active balancing is required.

Notes: 1. Before purchasing, please check the voltage of each battery cell to ensure it is normal! Replacing the protection board will not work if the battery is abnormal. Soldered batteries are not returnable or exchangeable! 2. Before installing the protection board, carefully check that the positive and negative poles of the battery match the positive and negative poles on the protection board. Connecting the protection board incorrectly will damage the module! 3. Lithium battery protection boards cannot be used with lithium iron phosphate batteries, xenon lamps, high-power hand drill battery packs, electric fishing machine battery packs, electric bicycle battery packs, children's car batteries, or products with motors or motors. Customers purchasing these combinations should take note! 4. Always charge the battery with a charger specifically designed for lithium batteries. Never use a lead-acid battery charger. Lead-acid batteries may cause high voltage to break down the MOSFET on the protection board, causing the protection board to overcharge and fail to protect. Polymer battery charger voltage = number of battery strings x 4.2V.
