xcluma MicroUSB 5V 18650 Lithium Battery 1A Charging Module W TP4056 Protection (1 PC)

Current- 1a adjustable charge precision- 15 percent input voltage- 45v-55v full charge voltage- 42v
Led indicator- red is charging green is full charged input interface- micro usb work temperature- -10 cto +85 c inversed polarity- no
Note: 1 ampere meter can only be connected to 5v input end of the module 2 it is better that the charging current is 37 percent of the battery capacity if you charge to the battery of 1000mah, current of 400 is enough
3 the connection wire should not be too thick 4 make sure the connect point is good 5 if the input voltage is too high, like 52v, the current will be less than 1000ma, it is normal it is protection function, auto-substract the charging current to avoid burn damage to chip 6 no reveral polarity
