Lithium Batteries are extremely sensitive and dangerous to use without a proper protection circuit. This BMS circuit can be easily used and installed in a 18650 Li-ion Battery. Since this is rated for 1S battery, the operating voltage is 3.2V to 4.2V. It supports 2A of current. This is a Battery Management System circuit that monitors the charging and discharging profile of the battery. It is designed for more than 20,000 hours of operations to protect from over voltage, over current, over charge related conditions.
