Li-Ion BMS Protection Board 1S - 3.7V 3A

The 1S 3.7V 3A Li-Ion BMS (Battery Management System) protection board is an essential device for any Lithium-Ion battery installation. With its compact dimensions of 18 x 3.6 mm, this board is designed to protect your batteries from overcharging, short circuit and overcurrent, ensuring their durability and safety.

This protection board is specifically designed for a nominal voltage of 3.7V and requires a 4.2V charger for optimal charging. It is sold individually and is ideal for a variety of applications, whether for DIY projects, electronic devices, or personal power systems.

To ensure safe operation of the BMS protection board, be sure to reconnect the terminals correctly: B+ to the + of the battery, B- to the - of the battery, P+ and P- for output and charging. Before installing, make sure the battery is compatible and the voltage difference between each battery does not exceed 0.05V.

Please note that the card is sold without a battery. Remember to check the battery voltage with a multimeter before installation, especially if you are replacing an old electronic card. Proper operation of this card will ensure the safety of your battery-powered devices.
