60V 33Ah LiFePO4 Battery Compatible with Wenbox U7

A replacement battery developed for verified Wenbox U7 electric bicycle configurations used by distributors, workshops and riders across Russia and neighboring Eurasian markets.

When should a U7 battery be replaced?

Common replacement triggers include reduced usable range, voltage sag under acceleration, inconsistent charging, damaged connectors or an enclosure that no longer seals correctly. These symptoms should be checked together with the charger, controller and wiring. Our battery is a compatible aftermarket solution; Wenbox is a separate third-party vehicle brand and is not affiliated with our factory.

Reference specification for a verified replacement

Five checks before approving a sample

1. Confirm the exact bicycle model and original battery voltage.
2. Measure the usable compartment and mounting clearance.
3. Photograph charge and discharge connectors from several angles.
4. Verify polarity, charger output and controller power.
5. Define the lowest temperature, route conditions and expected load.

This verification reduces the risk of ordering a pack that is electrically correct but physically unsuitable.

Cold-weather and fleet options

For Russian winter service, the engineering review can include enclosure insulation, charging temperature limits, cable flexibility and conservative current settings. Fleet operators may also request repeatable labeling, batch records, matching chargers or charging-cabinet integration. Actual range varies with temperature, payload, speed, terrain and vehicle condition.

Available customization

• Voltage, amp-hour capacity, discharge current and cell arrangement
• Enclosure dimensions, mounting points, color, handle and logo
• Charge socket, discharge plug, cable gauge, length and direction
• Water resistance requirements and BMS protection thresholds
• Optional Bluetooth monitoring, data communication and GPS-related functions
• Packaging, labels, charger and charging-cabinet matching
