OHRIJA OLED Smart Lithium-Ion Fast Charger Series – Premium Dual-Color Aluminum Power Supply with Live Telemetry Screen (5A & 3.5A Models) for 36V, 48V, 60V, and 72V E-Bikes & Scooters

Track your active power metrics with digital precision. The OHRIJA HRH300 OLED Smart Fast Charger Series delivers an advanced, hyper-compact energy replenishment station engineered specifically for modern electric bikes, high-velocity stand-up scooters, and custom lithium-ion battery blocks. Housed inside a striking, compact dual-color aluminum alloy enclosure (measuring just 135mm × 90mm × 50mm), this charger drops the bulky weight of industrial blocks to offer an ultra-portable 0.7kg (1.5 lbs) performance setup featuring an integrated OLED live digital monitoring screen.

Tuned with automated 3-stage smart charging logic (CC/CV/Trickle), the HRH300 continuously balances your cell strings, maximizing your overall capacity retention while keeping your workshop or commuter kit highly streamlined.

🚀 Key High-Performance Features

Integrated Live OLED Telemetry Display: Keep absolute visibility over your staging bench. Displays active voltage output, charging status, and power curves in real time (Note: Screen parameters carry a localized 10% operating reference tolerance).
Ultra-Compact Aluminum Alloy Shell: Blends high structural durability with heat-dissipating aluminum architecture. Features a premium black-and-red chassis that safely protects internal boards during transport.
Intelligent 3-Stage Smart Microprocessor: Safeguards your premium cells by automatically transitioning your battery pack from bulk Constant Current (CC) to precision Constant Voltage (CV) before completing with a delicate Trickle charging phase.
Ultra-Lightweight & Portable Footprint: Weighing an incredibly light 0.7 kg, this pocket-sized power core easily slides into a commuter backpack or scooter storage bag for fast trackside topping.
Global Structural Compliance Marks: Fully certified under international CE, FCC, and RoHS safety and manufacturing benchmarks (High-concerned chemical: None).

36V Platform Pro	36V Nominal Lithium	42.0 Volts DC	5.0 Amps Fast Charge	DC2.5 Coaxial Connector
48V Platform Pro	48V Nominal (13S)	54.6 Volts DC	5.0 Amps Fast Charge	DC2.5 Coaxial Connector
60V Platform Pro	60V Nominal Lithium	67.2 Volts DC	3.5 Amps Accelerated	DC2.5 Coaxial Connector
72V Platform Pro	72V Nominal Lithium	84.0 Volts DC	3.5 Amps Accelerated	DC2.5 Coaxial Connector

⚠️ Critical Battery Chemistry Restriction Warning

LITHIUM-ION ONLY: This smart charger is calibrated exclusively for standard Lithium-Ion (Li-ion) and Lithium Polymer (LiPo) battery chemistries.
DO NOT USE ON OTHER BATTERIES: Never connect this charger to Lithium Iron Phosphate (LiFePO4), Lead-Acid, or Ni-MH configurations. Doing so can prevent proper cutoff safety matching and compromise your battery bank.

🛡️ 4-Tier Hardware Core Protection Grid

Built to ensure peak workspace protection and maintain optimal terminal safety during heavy-duty fast charging, the internal board deploys four automated safety disconnects:

Short-Circuit Protection (SCP): Kills active output paths immediately if positive and negative pins bridge or ground out.
Over-Voltage Protection (OVP): Caps upper limits precisely at the target voltage threshold (42V, 54.6V, 67.2V, or 84V) to eliminate battery bloating risk.
Over-Current Protection (OCP): Locks the charging current tightly at the designated 5A or 3.5A limit, preventing cell saturation spikes.
Over-Temperature Protection (OTP): Automatically cuts current flow if internal board temperatures exceed safe thermal limits under extended ambient loads.
