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.
- Electric vehicle — Light electric vehicles (LEVs) need balanced charge current to protect pack life while keeping charge time reasonable.
- RV — RV and leisure batteries benefit from multi-chemistry chargers that handle lead-acid and lithium alike.
How to Specify This Charger
Battery chemistry. Lead-acid charges in three stages (bulk/absorption/float) to ~2.4–2.45 V/cell and needs float maintenance.
Voltage match. The unit is built for 12V batteries with an end-of-charge output of 14.4V. Confirm your pack's series count against this termination voltage before integration.
Charge current. Rated output current is 25A. 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 Custom. 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, Output Short Circuit 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.
