Product Description


This is a charger for 5-series Lithium ion battery packs, nominally 18.5V (5 x 3.7V), which charges at 21V volts (5 x 4.2V). The bulk charge current is 2.0A. It is a multi-stage li-iron Li-ion recharger with universal AC input. Includes a slow start feature and a 4-segment gas gauge.

This battery charger complies with applicable safety agency requirements, and it is listed with UL, cUL PSE and CE

Input: 100~240V

Output: 21V 2.0A

Suit for Battery: 18.5 Volt (4Cells) 3~25Ah Li-ion Battery

Charge Process: smart 4-stage,  CC(pre-charge)-CC(bulk)-CV-cutoff

Charger Indicator: With 25% 50% 80% 100% charging indicator

Output Protections: Short-circuit, Reverse Polarity

Safety Approval: CE UL PSE

Size: 120 x 67 x 41mm


It is a state-of-the-art battery charger that can be used on-demand, or left permanently on the battery for maintenance.. It uses energy-saving techniques and and and advanced charge precision. The slow-start function helps battery cycle life, especially with deeply discharged batteries. The charger is fully isolated from the mains, has universal AC input, and a removable AC cord. Will accurately lithium-ion packs.

It is programmed auto 4 stages (Pre-CC-CV-Cutoff) charging process, designed for 3~25Ah Lithium battery pack. Stage "precharge" 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 "CC" will give bulk current charging (up to 50W). Then, "CV" 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, GC60-12L5 can display the charging process, indicating the battery capacity from 25% to 100% timely. This is helpful for user.
For more safety, GC60-12L5 will enter protection mode when the battery polarity reversed our the output connectors shorted.
