Hobby Mechatronics 4s 2A Bms 16.8V Type C Lithium Battery Charger Module 18650 Li-Ion Battery Step-Up Boost

4S 16.8V 1A Li-ion & Lipo Battery Charger Circuit

Product features

1. Switching frequencies up to 1MHz compensate for voltage loss in half-CV mode.
2. The internal resistance of the battery and the monitoring resistor are automatically charged.
3. Protection battery voltage is lower than input voltage and battery short circuit.
4. Strong adaptability to input power supply, driving capacity is limited by battery over-voltage protection.
5. 8.4V/12.6V/16.8V version of DC 3-6V input voltage (DC 3.7V 5V is recommended).
