3S 12V 18650 Lithium Battery Protection Board (BMS) 10A

✅ Overcharge Protection: Prevents each cell from exceeding its safe voltage limit (usually ~4.2V). ✅ Over-discharge Protection: Cuts off the load if any cell drops too low (typically ~2.8V), avoiding deep discharge damage. ---Overcharge, over-discharge, over-current, and short-circuit protection---- ✅ Overcurrent & Short Circuit Protection: Limits discharge current to ~10A and disconnects instantly if a short circuit occurs. ✅ Cell Balancing (if supported): Ensures all three cells charge evenly, improving lifespan and efficiency. The 3S 12V 18650 Lithium Battery Protection Board (BMS) 10A is ideal for DIY electronics, robotics, automation, and prototyping.
