1. Product Overview
The BAKTH-32700-4S2P is a 12.8V 12Ah lithium iron phosphate (LiFePO4) battery pack engineered for electric bicycles, integrating 8 high-performance 32700 cylindrical cells in a 4-series 2-parallel configuration. With a cycle life of over 2000 cycles at 100% depth of discharge (DOD) and a capacity retention rate of ≥70% at end-of-life, it delivers reliable long-term power. Weighing 1.77kg and measuring 151×98×97mm, it balances compactness with energy density, fitting seamlessly into most e-bike frame designs.
2. Application Scenario: Urban Commuter E-Bike Fleet
A regional e-bike sharing company in Guangzhou, China, faced persistent issues with lead-acid batteries in its 500-unit fleet: short cycle life (average 800 cycles), high maintenance costs, and frequent replacements disrupting service. In Q1 2025, the company replaced 100 lead-acid batteries with BAKTH-32700-4S2P packs to test performance.
3. Performance Outcomes
Longevity & Cost Efficiency: Over 12 months, the LiFePO4 packs maintained 85% of their original capacity, while the remaining lead-acid batteries required replacement after 9 months. The projected 2000-cycle lifespan of the BAKTH packs is expected to reduce annual battery replacement costs by 60%.
Operational Reliability: The packs operated stably in temperatures ranging from -5°C to 38°C, with no instances of overheating or power failure. Their 3.5% monthly self-discharge rate ensured bikes remained ready for use even during low-demand periods.
User Experience: Riders reported consistent power delivery across the battery’s discharge cycle, eliminating the sudden power drop common with lead-acid batteries. This improved customer satisfaction scores by 18%.
4. Competitive Advantages
Safety Certifications: Compliance with UN38.3, MSDS, ISO9001, and ISO14001 standards ensures adherence to global safety and environmental regulations, critical for fleet operators targeting international markets.
Customization Flexibility: BAKTH offers tailored connectors, cable lengths, and waterproofing solutions, allowing the pack to integrate with diverse e-bike models without modifications.
Scalable Supply: With a minimum order quantity (MOQ) of 1 unit and a monthly production capacity of 1000 packs, the manufacturer accommodates both small-scale trials and large fleet rollouts.
5. Conclusion
The BAKTH-32700-4S2P LiFePO4 battery pack addresses key pain points of e-bike operators, combining durability, reliability, and cost-effectiveness. Its performance in the Guangzhou fleet trial demonstrates its potential to become a preferred power solution for urban e-bike sharing services, delivery fleets, and personal commuter bikes.
