Weather-Resistant Battery Compatible with Wenbox U-B

A custom LiFePO4 replacement solution for verified Wenbox U-B electric bicycles used in urban commuting, delivery and regional service programs across Russia and Eurasia.

The enclosure is part of the battery system

Rain, road spray, vibration and repeated handling place mechanical demands on a battery beyond voltage and capacity. A replacement pack should match the bicycle bay, mounting points, connector orientation and cable exit while providing the sealing level required by the project. Wenbox is a third-party vehicle brand; Airuisi supplies independent compatible batteries after technical verification.

Design inputs for a protected installation

Water resistance requires clear boundaries

Customers should specify the expected exposure to rain, splashing, washing and condensation. The engineering review may cover enclosure joints, cable glands, port covers and drainage strategy. Water resistance must be evaluated for the approved battery design and does not mean the pack can be submerged or charged while wet.

Cold streets and warm charging rooms

Temperature transitions can create condensation and affect charging behavior. For Russian winter use, provide the minimum outdoor temperature, storage location and charging-room conditions. BMS temperature protection, insulation and cable selection can then be reviewed for the operating profile. Range varies with climate, load, speed, terrain and battery condition.

Electrical and digital options

• LiFePO4 cell configuration, voltage, capacity and discharge current
• Overcharge, over-discharge, over-current, short-circuit and temperature protection
• Cell balancing, battery monitoring and configurable BMS parameters
• Optional Bluetooth data, communication functions and GPS-related features
• Matching charger or charging-cabinet connection
• Logo, multilingual labels and custom export packaging

Prototype before mass production

Airuisi develops the mechanical structure, BMS, wiring and enclosure from the confirmed requirements. A prototype is produced for fit and functional testing, followed by sample approval, mass production and final inspection across five dedicated production lines.

Information for engineering review

Send the original battery label, compartment dimensions, mounting photographs, connector details, charger output, controller power, environmental requirements, quantity and destination. CE, UN38.3 and MSDS support is available for the confirmed product.
