Wenbox W21 60V 60Ah LiFePO4 Replacement Battery for Russia

A dealer-ready replacement platform for regional stock, fleet maintenance and long-distance riding. This 60V 60Ah LiFePO4 battery is developed for Wenbox W21 electric bikes after the original pack, compartment, connectors, polarity, charger and controller have been verified. It is aimed at importers, repair networks and fleet operators serving Russia, Kazakhstan, Belarus and nearby Eurasian markets.

60V 60Ah configuration for replacement stock

The 60Ah energy capacity supports extended duty cycles when the battery, vehicle load, route and controller are correctly matched. LiFePO4 chemistry provides stable thermal behavior and practical cycle performance for commercial service. Actual range depends on speed, rider and cargo weight, tire pressure, hills, wind, temperature and battery age.

Compatibility is verified, not assumed

Wenbox W21 vehicles can have different battery housings, plugs or controller settings. Before production, our engineers review the original battery label, length, width and height, mounting position, charge/discharge sockets, cable polarity, charger output and controller rated/peak current. Please send clear photos and measurements. For modified bikes or mixed fleets, a prototype sample is recommended before bulk production.

Designed for cold-region operating plans

Cold temperatures temporarily reduce usable energy and charging acceptance. For northern markets we can customize BMS temperature thresholds, low-temperature charging protection, thermal insulation and an optional heating strategy. Batteries should be stored, charged and operated within the approved temperature range. Never charge a frozen pack with an unverified charger.

OEM and ODM choices

• Custom voltage, capacity and continuous/peak current
• Enclosure size, color, mounting points and carrying handle
• Private logo, labels, cartons and multilingual documentation
• Charge port, discharge plug, cable length, gauge and polarity
• Smart BMS data, Bluetooth or specified communication protocol
• GPS tracker and charging-cabinet compatibility
• Water-resistant structure and high/low-temperature design

Our project flow is requirement confirmation, electrical and enclosure design, prototype assembly, sample testing, customer approval, mass production and outgoing inspection. The starting MOQ is 100 sets. Five production lines support output of up to 1,000 battery packs per day depending on the approved specification and material plan.

Factory manufacturing and quality control

Foshan Airuisi Intelligent Technology Co., Ltd. is a high-tech enterprise specializing in lithium battery R&D, manufacturing and OEM/ODM service. Production control covers incoming cell checks, cell matching, welding, insulation, BMS installation, enclosure assembly, electrical testing and appearance inspection. Confirmed export projects can receive the supporting documentation required for transport and destination-market preparation.
