A protection board and a battery management system (BMS) are both used to protect lithium-ion batteries, but they serve different functions.
A protection board is a small electronic circuit that is typically placed between the battery and the device it powers. It is designed to prevent overcharging, over-discharging, and short circuits.
Protection boards are relatively simple and inexpensive, and they are often used in applications where only basic battery protection is needed.
