OHRIJA HRH900N 75.6V 12A Ultra-Fast Smart Charger for 18S 60V Lithium-Ion Battery Packs (High Power | Digital Display | Aluminum Shell)

Power up your high-capacity electric bikes, e-scooters, and custom lithium battery builds in record time with the OHRIJA HRH900N 75.6V 12A High-Power Fast Battery Charger. Engineered specifically for 18-string ($18\text{S}$) 60V Lithium-Ion (NMC / Li-Co) battery packs, this commercial-grade charger delivers over 900W of continuous output power.

 Encased in a rugged, heat-dissipating aluminum alloy shell, the HRH900N utilizes a precise 3-stage CC / CV / Trickle charging protocol paired with an integrated digital display screen for monitoring real-time voltage and current parameters.

⚠️ Important Battery Compatibility & Safety Guidelines

CRITICAL VOLTAGE & BATTERY SPECIFICATIONS:

• STRICTLY FOR 18S 60V LITHIUM-ION BATTERIES ONLY: Engineered exclusively for 18-series ($18\text{S}$) Lithium-Ion battery packs with a 75.6V maximum peak charge cutoff ($18 \times 4.20\text{V} = 75.6\text{V}$). DO NOT use on Lead-Acid batteries or 16S / 20S battery configurations.

• High Output Current (12.0 Amperes): Delivers rapid charging power ($>900\text{W}$). Ensure your battery pack's BMS (Battery Management System) and charge port wiring are rated to continuously handle a 12A charging input.

• Multi-Stage Intelligent Safety Protection: Fully integrated protective circuitry guards against Short Circuit (SCP), Over-Voltage (OVP), Over-Current (OCP), and Over-Temperature (OTP).

• Operating Environment Warning: Always operate the charger in a well-ventilated, dry area away from direct heat sources and high humidity.

🚀 Key High-Performance Features

• 900W+ Ultra-Fast Charging: High amperage 12A output slashes charge times significantly compared to standard 2A–4A maintenance chargers.

• Smart Real-Time Digital Display: Integrated digital screen displays live output voltage and current parameters for precise charging status monitoring.

• Advanced 3-Stage CC/CV/Trickle Logic: Charges at constant current (CC) for speed, switches to constant voltage (CV) for cell balancing, and finishes with trickle maintenance to prevent overcharging.

• Heavy-Duty Aluminum Alloy Casing: Durable aluminum shell provides maximum thermal conductivity and impact protection for shop, field, or garage environments.

• Comprehensive Global Certifications: Certified compliant with international CE, FCC, and RoHS quality and safety standards.

Product Introduction

1. Efficient Charging

Add a precharge phase. Adopting advanced switching power supply technology, the charging efficiency is as high as 85% or more, shortening the charging time and reducing energy consumption.

2. Constant voltage and constant current charging mode

The charger works in constant current (CC) mode until the battery voltage approaches the set value, and then switches to constant voltage (CV) mode to ensure the safety of the charging process and avoid overcharging.               Full automatic break

3. Intelligent temperature control

The built-in temperature sensor can monitor the charger temperature in real time. When the temperature exceeds the safe range, it automatically reduces the charging current or suspends charging to prevent overheating.

4. Multiple protection functions

· Overvoltage protection: When the voltage exceeds the safe range, the charger automatically cuts off the power to prevent battery damage.

· Overcurrent protection: When the current exceeds the rated value, the output current is automatically limited to protect the battery and charger.

· Short circuit protection: The charger has a short circuit protection function to avoid dangers caused by short circuits.

· Reverse connection protection: When the positive and negative poles of the battery are reversed, the charger automatically stops working to avoid damage to the battery and charger.

5 LED indicator lights

The charger is equipped with LED indicator lights to display the current charging status:

· Red light: Charging.

· Green light: Charging completed or standby.

Frequently asked questions

1. Not working

· Check if the AC input voltage is 110 or 220V

· Check if the input AC terminal is connected correctly and if the fuse is damaged

· Check if the output connector is connected correctly, if it matches, and if the fuse is damaged

· Check if the BMS system is protected

2. How loud is the noise

Since there is a fan inside the charger, the noise is about 50-70 db
