Walfront DDTCCRUB 3S 1A Battery Charger Module Li ion Step Up Boost

Compensate voltage loss: switching frequencies up to 1 MHz, compensate for voltage loss in CV mode 【AUTOMATICALLY CHARGED】 - The internal resistance and the tracking resistance of the battery are charged automatically Short circuit protection: the battery voltage is less than the input voltage and short circuit of the battery 【Strong adaptability】 - Strong adaptability to the input power supply, the driving capacity is limited. 【Input Voltage Range】 - 12.6V version of input voltage DC 3-6V (DC 3.7V 5V is recommended)
