[Battery charging method] first turn ON the charger and the green light is ON; Turn ON the battery box switch to the "ON" position, then the battery indicator light is ON; Connect the charger output terminal to the battery box "DC IN/OUT" position, when the red light is on, it indicates that the charging starts (if the battery is fully charged, the green light connected to the output of the Charger remains unchanged); Because this charging circuit adopts the slow charging design (fast charging affects the battery life), therefore, the charging time is generally more than 8 hours; Until the red light on the charger turns green, the battery is full.

[Battery power supply method]]

battery power supply connect one end of the power cord (DC5.5 * 2.1 double-head line) to the "DC IN/OUT" of the battery box, switch to "ON", and connect the other end to various devices that need electricity, just turn on the switch; Overload is used inside the battery box. Overvoltage. Short circuit protection circuit; When the battery is not in use, the internal circuit will automatically cut off the power supply, resulting in no voltage output. At this time, the power output can be restored as long as the charging step is repeated.
