Robotics & DIY: A reliable 8.4V power source for projects involving dual-cell lithium configurations.
Is this charger compatible with a 7.4V battery? Yes. Lithium-ion packs are often labeled by their nominal voltage (7.4V), but they require an 8.4V charger to reach a full 100% charge.
Will a 2A charger work if my old one was only 1A? Yes. Your device or battery BMS will only "pull" the current it is rated for. A 2A capacity provides more power overhead, allowing the charger to run more efficiently.
Why does the light stay Green when I plug in my device? This indicates either the battery is already full, the internal protection circuit has tripped, or there is a connection issue. Ensure the DC plug is firmly seated in the charging port.
