Is this charger compatible with a 36V battery? Yes. Lithium-ion packs are typically labeled by their nominal voltage (36V), but they require a 42V charger to reach a full 100% state of charge.
Can I use a 2A charger if my original was 1.5A? Yes. A 2A capacity provides more power overhead, allowing the charger to work efficiently without overheating while your battery's BMS manages the intake.
Why is the LED Green when the battery is still empty? This often indicates a connection issue, a blown fuse in the battery pack, or that the battery's internal protection circuit (BMS) has tripped. Ensure the DC plug is firmly seated in the port.
