Wheel Swapping
Jarwin 2/3-Wheel Swapping Solutions

2/3-Wheel Swapping for
E-Moto Fleets

Jarwin’s semi-solid LiFePO4 batteries for 2/3-wheel swapping are purpose-built to power urban last-mile mobility, combining high-performance semi-solid chemistry with a platformized design tailored for e-moto fleets. Engineered for seamless integration with swapping stations, our solutions deliver lower total cost of ownership (TCO), higher fleet uptime, and enhanced safety—making them the ideal choice for on-demand delivery, shared fleets, and urban logistics operators worldwide.

  • Capacity Options: 40Ah / 43Ah / 47Ah (built on 20S / 24S standard platforms)
  • Voltage Platform: 64V–72V (compatible with standard swapping station interfaces)
  • Form Factor: Unified design with quick-release handle/latch for fast, tool-free swaps
  • Chemistry: Semi-solid LiFePO4 (higher energy density & thermal stability vs. conventional Li-ion)
  • Communication: CAN / RS485 connectivity (customizable protocols) for BMS/ billing system integration

Lead-Acid to Lithium (LiFePO4) Conversion Solutions

Meticulous LiFePO4 cell selection stands as the cornerstone of Jarwin’s lead-acid to lithium conversion solutions—one of the most critical determinants of not just core performance metrics (lightweight, longevity, and usable capacity), but also operational reliability, total cost of ownership, and compliance with global industrial standards for our B2B partners.

Drop-in Replacement Advantage

Our LiFePO4 batteries are engineered for true drop-in compatibility, directly replacing standard lead-acid form factors without modifications to vehicle wiring, mounting, or charging systems. This seamless transition delivers:

Certification Compliance

We ensure that all our lead-acid to lithium conversion batteries meet the necessary global safety and performance certifications, including:

  • UN38.3: Certified for safe air, sea, and road transport
  • IEC 62133: Compliant with international lithium battery safety standards
  • GB/T: Meets China’s national mandatory and recommended standards
  • Additional certifications: CE, FCC, and other regional certifications available to support global market entry.
