48V Li-Ion Charger 54.6V/2A – Reliable Protection for Your Electric Vehicle Battery
The most common cause of premature battery degradation in electric vehicles is using an incorrect charger or repeated overcharging. If you own an electric scooter, e-bike, or moped with a 48V Li-Ion battery, you need a charger that knows exactly when to cut the power. This unit does exactly that—automatically and reliably.
Note: Please check the connector type and voltage specifications on your original charger or vehicle manual before placing your order. Ensuring connector compatibility is the responsibility of the buyer.
Why choose this charger? (Key Benefits):
- Automatic 54.6V Cut-off — Once the battery is fully charged, the current stops automatically, giving you peace of mind against overcharging.
- Triple Safety Protection — Built-in safeguards against overvoltage, overcurrent, and short circuits; operates safely even with unstable power supplies.
- Clear Dual-Colour LED — Red indicates charging, while green confirms the cycle is complete. No need for apps to monitor your status.
- Quiet Cooling Fan — Designed for low-noise operation, so you can charge your vehicle in your bedroom or office without distraction.
- Compatible with 12Ah–20Ah Batteries — The 2A output provides an optimal balance between charging speed and cell longevity.
- Universal 100–240V AC Input — Works perfectly with any standard European power outlet without the need for an adapter.
- 5 Connector Types Available — Choose from 8mm Coaxial, DC 5.5mm, GX16, XLR, or IEC C13 to perfectly match your vehicle.
Performance and Technical Specifications
This charger utilizes the CC/CV (Constant Current / Constant Voltage) charging method, which is the industry standard for maintaining the health of Li-Ion batteries over many years. The 54.6V DC output is precisely calibrated for 13S Li-Ion battery packs, the standard configuration for most 48V electric vehicles on the market. With a maximum power output of ~110W, it ensures a stable and efficient charge, even for 20Ah batteries.

Frequently Asked Questions
How do I know if this is compatible with my vehicle?
Check the label on your battery or your original charger. If it specifies 48V Li-Ion, it is electrically compatible. Simply verify your connector type before selecting your version.
Can I leave the vehicle charging overnight?
The automatic 54.6V cut-off significantly reduces the risk of overcharging. However, as a best practice for all Li-Ion batteries, we recommend disconnecting the charger once the LED turns green.
Does this work with 48V LiFePO4 batteries?
No. 48V LiFePO4 batteries require a charging voltage of approximately 58.4V. This charger is designed exclusively for 48V Li-Ion (13S) chemistry and should not be used with other battery types.
Is the cooling fan noisy?
Not at all. The internal fan is optimized for silent operation, making it suitable for use in residential or office environments.
Does it work in Ireland, Luxembourg, and Malta?
Yes. The 100–240V AC (50/60Hz) input is universal, meaning it works perfectly across all EU countries without needing an additional voltage adapter.
