OHRIJA 54.6V Smart Fast Lithium-Ion Battery Charger (2A / 3A / 4A / 5A) – Heavy-Duty CC/CV Power Supply for 13S 48V & 48.1V Outdoor Lithium Battery Packs

Ensure rapid, safe, and balanced charging for your 48V e-bike and outdoor lithium-ion energy storage systems. The OHRIJA 54.6V Smart Lithium Battery Charger (Model: HRH300) is engineered specifically to deliver stable, high-efficiency charging to 13S (48V / 48.1V nominal) lithium-ion and LiPo battery configurations. Available in 2A, 3A, 4A, and 5A output current configurations (delivering up to 500W of total output power), this power supply charges your battery packs quickly while protecting delicate cell chemistry.

Featuring an advanced multi-stage Constant Current (CC) / Constant Voltage (CV) / Trickle charging algorithm, the HRH300 balances individual cell banks and automatically terminates power output when full capacity is reached, maximizing battery service life and safety.

🚀 Key High-Performance Features

• Dedicated 13S 48V Lithium Calibration: Factory-calibrated to a precise 54.6V DC cutoff voltage, making it the perfect match for standard 13S 48V / 48.1V lithium-ion e-bike battery architectures.

• Selectable Amperage Rates (2A to 5A): Choose the ideal charging rate for your pack size—from gentle 2A trickle charges up to 5A (500W peak output) fast charging for large-capacity packs.

• Multi-Stage CC/CV Charging Profile: Utilizes an intelligent 3-stage charge process (Constant Current $\rightarrow$ Constant Voltage $\rightarrow$ Trickle Maintenance) to ensure deep, balanced cell saturation without thermal degradation.

• 4-Layer Industrial Protection Matrix: Built-in safeguards defend against Short Circuiting (SCP), Over-Voltage (OVP), Over-Current (OCP), and Over-Temperature (OTP).

• Compact & Rugged Form Factor: Encased in a compact 135mm × 90mm × 50mm housing weighing just 0.7kg, ideal for home charging setups or taking along on outdoor trips.

• International Safety Certified: CE, FCC, and RoHS certified to meet high electrical performance and environmental safety standards.

📊 Electrical Specifications & System Blueprint

Please confirm your battery pack's nominal voltage and series cell count before ordering:

- 100% new, high quality, super protection.

- Connectors: DC5.5-21mm* Three-pin XLR 18MM*GX16 12MM and RCA 8MM

- Charging indicator: red when charging, green when full

- Security protection: OVP/OCP/ overload protection/short circuit protection

- Color: Black

- Plug EU/US/AU/UK(Please select the plug in your country, we will ship according to the plug you choose,)

 

Charger use and maintenance:

 

1. When charging, connect the plug to the battery first, and then connect the AC. When full, cut off the AC and unplug the battery. If you unplug the battery first when charging, especially when the charging current is large (red light), it is easy to damage the charger.

 

2. When the LED indicator turns green, please continue charging for 2-3 hours.

 

3. Please do not use up the battery power and then charge it. Otherwise, the battery cannot be protected or may even be damaged.

 

(4) Long-term shallow discharge battery, about 3 months or so, for a deep discharge, is the so-called re-lighting, which is conducive to activating the battery deep long-term immobile substances. Glow-in-the-dark refers to the ride controller battery undervoltage protection action.

 

5. Please use the charger in a dry place.

 

6. Do not always connect to the power supply when you are not using the charger.

 

7. Please confirm your battery, as it is used to charge lithium batteries. Do not use the charger on the LiFePO4 battery; otherwise, the charger will become very hot
