Lithium Battery Electrical Bike Charger

L100-XXG is a main member of digital-chargers from Green Digital Power-tech Co., Ltd. It represents today's new technology for 12.8V(4s) ~ 34.8V(12s) Li-ion/Polymer/FePo4 battery pack charging. L100-XXG Programmed 3 auto stages ( IP-Im-Um) charging process, It is designed for 3~25Ah Li-ion/Polymer/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. Then, "Um" stage is followed, the output voltage is Limited on 14.4V(for 4S LiFePO4) or 16.8V(for 4S Li-ion/polymer), until the Charge current declined to 0.4A. At this stage, the battery is charged Completely and the charger will cut off output automatic.

Further, L100-XXG can display the charging process, indicate the battery Capacity from 25% to 100% timely. This is helpful for user.

For more safety, L100-XXG will inter protection mode when the battery Polarity reversed or the output connectors shorted.
