5 uds/1pc 2S 3S 3,7 V elevador QC carga rápida polímero litio placa de batería 15W interruptor síncrono Boost módulo de cargador equilibrado

1. Support QC fast charging

2.15W synchronous switch boost charging

3. Boost charging efficiency of 94%

4. Two or three strings of lithium batteries can be set for charging

5. Band balanced charging

6. Adjustable charging current

7. Input overvoltage and undervoltage protection

8. Adjustable charging timeout protection

9. Output overcurrent, overvoltage, and short-circuit protection

The module is suitable for 3.7V lithium batteries with two or three strings. By short circuiting, it defaults to two strings. When two strings are used, the module's built-in battery balancing function can be used, which is very practical. The input can be done through TYPE-C port and solder wire. When the TYPE-C port is connected to a fast charging power supply, the charging voltage is automatically adjusted to improve efficiency. If the input voltage is lower than the battery voltage when the solder wire is input, the module can only work in boost mode.
