Uninterrupted power supply

This expansion board is capable of charging the batteries and simultaneously providing a power output for the system (from an external power supply). If the external power supply is not available, it automatically switches to the battery output.

Attention: 18650 batteries and Compute Module 4 not included. The length of the battery must be less than 67mm.

SAFETY INSTRUCTIONS

Li-ion and Li-po batteries expose the user to various risks. They can cause fire, property damage and injury if not properly charged or used. Do not reverse the polarity when charging or discharging the battery. Do not use an inferior charger/charging panel to recharge the battery. Do not mix used batteries with new ones. Avoid using batteries of different brands. Batteries should be stored carefully away from flammable and explosive materials and out of reach of children.
