Description

The Lithium-ion battery balance and protection extension board is a protection module for rechargeable battery pack; it is highly

integrated, and specially used for WONDOM’s audio amplifier boards. The Lithium-ion battery balance and protection extension board works constantly to monitor each cell’s voltage, the current of charge or discharge, and the temperature of the environment to provide overcharge, over-discharge, discharge overcurrent, short circuit, charge overcurrent and over-temperature protections, etc. The Lithium-ion battery balance and protection extension board provides external bleeding for cell-capacity balance function to avoid

unbalanced capacity between each cell. Thus, the batteries can work for longer.
