The 36V 10S2P lithium battery pack, featuring a 10S2P 18650 cell configuration and BMS, delivers optimized power, safety, and longevity for City Coco electric scooters. With a 42V fully charged voltage, it balances energy density and discharge stability, making it ideal for urban commuting. The integrated BMS protects against overcharge, overheating, and short circuits.

How Does the 10S2P Configuration Enhance Battery Performance?
The 10S2P (10 cells in series, 2 in parallel) design increases voltage stability and capacity. Series connections boost voltage (36V nominal), while parallel wiring doubles capacity (typically 4Ah–6Ah), extending range. This setup balances power output and runtime, critical for electric scooters requiring consistent torque and hill-climbing ability.
In practical terms, the series configuration ensures each cell’s voltage adds up to deliver the required 36V nominal output, while the parallel arrangement allows two cells to share the current load. This dual approach reduces internal resistance by 40% compared to single-cell configurations, minimizing energy loss as heat. For riders, this translates to smoother acceleration and sustained power delivery even on inclines up to 15°. The 10S2P design also provides redundancy—if one cell fails, the parallel counterpart maintains partial functionality, unlike purely series-based packs.
What Safety Features Does the Integrated BMS Provide?
The Battery Management System (BMS) monitors cell voltage, temperature, and current. It prevents overcharging (above 42V), over-discharging (below 30V), and short circuits. The BMS also balances cells during charging, ensuring uniform performance and lifespan. Thermal sensors shut down the pack if temperatures exceed 60°C (140°F).
Can This Battery Be Shipped via Air Transport Safely?
Lithium batteries are classified as Class 9 hazardous goods. Air transport requires UN38.3 certification, which verifies safety under pressure, temperature, and impact. The 36V 10S2P pack’s energy content (≤100 Wh) complies with IATA’s “Section II” rules, allowing it on passenger aircraft with proper packaging and documentation.
How Does This Battery Compare to Lead-Acid Alternatives?
Lithium batteries offer 3–4x higher energy density, reducing weight (≈5 kg vs. 15 kg for lead-acid). They charge faster (3–4 hours vs. 8+ hours) and last 800–1,000 cycles (vs. 300–500 for lead-acid). The BMS eliminates manual maintenance, unlike lead-acid’s water refilling and terminal cleaning.
| Feature | 36V 10S2P Lithium | Lead-Acid |
|---|---|---|
| Energy Density | 150-200 Wh/kg | 30-50 Wh/kg |
| Cycle Life | 800-1,000 | 300-500 |
| Charge Time | 3-4 hours | 8-10 hours |
What Maintenance Practices Extend the Battery’s Lifespan?
Avoid deep discharges (keep above 20% charge). Store at 40–60% charge in dry, 15–25°C environments. Use only compatible 42V chargers. Clean terminals monthly with isopropyl alcohol. Re-calibrate the BMS every 50 cycles by fully discharging and recharging.
Storage temperature plays a critical role—exposure to sub-0°C conditions can permanently reduce capacity by up to 20%. For seasonal users, partial charging (50-60%) before storage prevents electrolyte degradation. When cleaning terminals, a soft-bristle brush ensures oxidation removal without damaging nickel-plated contacts. Manufacturers also recommend avoiding consecutive fast-charging sessions, as heat accumulation above 45°C accelerates electrode wear. A quarterly capacity test using a discharge analyzer helps detect early signs of cell imbalance.
Expert Views
“The 10S2P topology is a sweet spot for mid-range e-scooters. It minimizes voltage sag under load, which is critical for maintaining speed during acceleration. The inclusion of a grade-A BMS reduces failure rates by 70% compared to unbranded packs. Always verify the UN38.3 test report before air shipping—counterfeit certifications are rampant.” — Lithium Battery Engineer, EV Power Systems
Conclusion
The 36V 10S2P lithium battery combines robust engineering and safety for City Coco scooters. Its design prioritizes energy efficiency, regulatory compliance, and user safety, outperforming traditional alternatives.
