Description

The 3 Series 40A 18650 Lithium Battery Protection Board 11.1V 12.6V with Balance is a high-performance battery protection circuit designed to ensure the safe and efficient operation of 3-cell lithium-ion batteries (commonly 18650 cells). This protection board is specifically engineered for 11.1V (nominal) to 12.6V (fully charged) systems, commonly used in electric bikes, drones, power tools, and other battery-powered devices. It provides overcharge, over-discharge, overcurrent, and short-circuit protection, preventing damage to the battery cells and enhancing the lifespan of the battery.

The board also includes a balance function that ensures the cells within the battery pack charge and discharge uniformly, improving performance and stability. It supports a continuous discharge current of up to 40A, making it suitable for high-power applications like electric vehicles, solar storage systems, and other power-hungry devices. This protection board is an essential component for maintaining the health of lithium-ion batteries, ensuring the safe and efficient operation of your devices while avoiding potential hazards such as thermal runaway or cell imbalance.
