Custom Connector Battery Compatible with Wenbox U-B

A made-to-order lithium battery for verified Wenbox U-B electric bicycles when the replacement project requires specific charge ports, discharge plugs, polarity and cable routing for Russia and Eurasia.

A connector that looks similar may still be wrong

Plug family, pin arrangement, polarity, current rating and cable direction must all match the vehicle and charger. An incorrect connection can damage equipment or create a safety risk. Wenbox is an independent third-party brand; Airuisi supplies compatible aftermarket batteries only after the actual interface has been verified.

Connector data required before production

How to photograph an interface correctly

1. Disconnect the battery and charger safely.
2. Photograph the full connector and the pin face in good light.
3. Include a ruler for size reference where possible.
4. Show cable direction, labels and wire colors without opening sealed components.
5. Provide polarity information from technical documentation or qualified testing.

Photographs support review but do not replace verified wiring data.

Cable design for cold climates

Low temperatures can reduce cable flexibility and stress poorly supported exits. For Russian winter projects, cable material, bend radius, strain relief and sealing can be reviewed together with BMS temperature limits. The customer should define minimum temperature, installation movement and exposure to moisture or road spray.

The rest of the pack remains customizable

• Voltage, capacity, discharge current and LiFePO4 cell configuration
• Enclosure dimensions, shape, color, mounting method and handle
• BMS protection parameters, balancing and battery monitoring
• Optional Bluetooth data, communication interface and GPS-related functions
• Matching charger or charging-cabinet requirements
• Logo, serial labels, multilingual instructions and export cartons

Sample verification prevents expensive mistakes

Airuisi develops a prototype after the requirements are confirmed. The sample is checked for fit, polarity, charging, discharge behavior and connector retention before the design enters mass production. Five production lines support ongoing replacement supply.

Request an interface review

Send the original battery label, connector photographs, confirmed polarity, charger data, controller power, compartment dimensions, quantity and destination. CE, UN38.3 and MSDS support is available for the finalized battery configuration.
