How to build Li-ion over-discharge protection board
I have an Arduino board with a pump attached to it, and for powering both, I''m using a 18650 battery cell with a DC-DC Boost Converter. I plan to leave it working even when I''m not home, and I know that if the battery over discharges, there will be trouble, so I would like to design an over-discharge protection board.
A battery protection unit (BPU) prevents possible damages to the battery cells and the failure of the battery. Such critical conditions include: Over-charge: is when the battery is charged over the allowed maximum capacity. High & low temperature: is when the internal temperature of the battery cells exceeds their safe operational temperature ...

What You Should Know before Buying Battery Protection Board
Smart Battery Protection Board: Smart battery protection boards incorporate advanced features like communication interfaces (e.g., I2C, SPI) and built-in monitoring and control capabilities. They allow for more precise control, data logging, and integration with external systems or microcontrollers.
The battery protection circuit disconnects the battery from the load when a critical condition is observed, such as short circuit, undercharge, overcharge or overheating. Additionally, the battery protection circuit manages current rushing into and out of the battery, such as during pre-charge or hotswap turn on.
