Target Applications

This charger is specified for the following use cases. Matching the charger to the application’s duty cycle and environment is the first step in a reliable design.

• E-bike — E-bikes demand lightweight, efficient charging with clean CC/CV termination to protect high-cycle Li-ion packs used in daily commuting.
• E-scooter — E-scooters rely on compact chargers with reliable thermal management for frequent, short-cycle urban use.
• AGV — AGVs (automated guided vehicles) run continuous duty cycles in warehouses, so chargers must support opportunity charging and high uptime.
• Mobility scooter — Mobility scooters need safe, silent, low-current charging suitable for assistive daily-use devices.
• Forklift — Forklifts require rugged, often high-voltage chargers with strong thermal and reverse-polarity protection for industrial shift operation.
• Electric vehicle — Light electric vehicles (LEVs) need balanced charge current to protect pack life while keeping charge time reasonable.

How to Specify This Charger

Battery chemistry. Li-ion (NMC/LCO) cells charge to ~4.2 V/cell; a 48 V pack terminates near 54.6 V and offers high energy density.

Voltage match. The unit is built for 10.8V batteries with an end-of-charge output of 12.6V. Confirm your pack’s series count against this termination voltage before integration.

Charge current. Rated output current is 20A. As a rule of thumb, charge time (hours) ≈ battery capacity (Ah) ÷ current (A) × 1.2 for the CV taper. Size current to your acceptable charge window and pack longevity target.

Connector. Default connector is 20. Custom connectors and harnesses are available under OEM/ODM to match your existing harness.

Certifications & Compliance

Certification availability depends on the exact model and target market. The listed marks indicate the compliance scope supported for this product family:

• CE FCC ROHS — CE marking for the European Economic Area.

Protection Features

Short Circuit Protection, Over Current Protection, Over Voltage Protection, Over Temperature Protection, Reverse Polarity Protection are built in to safeguard the battery and the end product during everyday operation.

OEM / ODM Customization

This charger is supplied as an OEM/ODM component. Typical customizations include output voltage and current tuning, connector and harness matching, enclosure and label branding, and firmware/indicator adjustments for your product line. Low-volume trial batches and full-production runs are both supported for qualified B2B projects.
