G60-12F4 is a main member of digital-chargers from Green Digital Power-tech Co., Ltd. It represents today's new technology for 12.8V(4s) Li-Fe battery pack charging. G60-12F4 programmed 3 auto stages (Ip-Im-Um) charging process, It is designed for 3~25Ah LiFePo4 battery pack. Stage "Ip" is a pre-charge function for deep discharged battery pack, this is helpful for battery's cycle life. When the battery recovered by pre-charge small current, stage "Im" will give bulk current charging (up to 50W). Then, "Um" stage is followed, the output voltage is limited on C.V point, until the charge current declined to 0.4A (for 3A C.C) or 0.2A (for 1.5A C.C.). At this stage, the battery is charged completely and the charger will cut off output automatic.
Further, G60-12F4 can display the charging process, indicate the battery capacity from 25% to 100% timely. This is helpful for user.
For more safety, G60-12F4 will inter protection mode when the battery polarity reversed our the output connectors shorted.

How to use:
1.Connect the AC cord to the socket, The "power" lamp will light on solid.
2.Connect positive charger clip (red) to positive battery terminal, the black clip to negative. (You can use other dc plugs to connect battery), the "25%~100%" lamps will light on flowing. If the battery polarity reversed or output shorted, 4 lamps will flashing, please check the setup.
3.Depend on the charged capacity, 25%~100% lamps will lights up solid sequence, until the battery is fully charged. Then you can power off the charger and disconnect the battery or you can charge a new battery if you need.
The table shows the duration of 80% state charged for an empty battery.
