1A 4.2V 3.7V 18650 LiPo Li ion Lithium Battery Charger MPPT Solar Charge Controller Module Module(without Pin)

【AUTOMATIC ADJUSTMENT】The battery charger module automatically adjusts the charging current according to the output capacity of the input power supply, when the input power supply voltage is removed, it automatically adjusts to a low-power sleep mode 【REDUCE HEAT RELEASE】The solar controller module has a pre-charge adjustment function, which is used to restore the deeply discharged battery in the initial stage of charging and minimize heat dissipation 【IMPROVE THE CHARGING RATE】The lithium battery solar charging module has a constant current/constant voltage operation with thermal regulation function, which can maximize the charging rate without the risk of overheating 【APPLICATION】The adaptive unit on the module can automatically adjust the charging current according to the output capacity of the input power supply, so SD05CRMA is very suitable for solar power systems or applications that need to lithium ion batteries or lithium polymer batteries 【USE PARAMETERS】Solar panel dedicated charging module charging module power supply voltage DC 4.4-6V, charging output voltage DC 4.2V, the maximum charging current / output current is 1A, but you can change the current by changing the value of R1 resistance
