Introduction
Globally, small power lithium batteries have replaced lead-acid batteries as the core power source for electric two-wheelers and cargo three-wheelers. Unlike large automotive power lithium batteries, these lithium power batteries for electric two wheelers and three-wheelers are designed for short-distance delivery, frequent charging, bumpy roads and portable swap applications.
Southeast Asia, South Asia and Africa see surging demand for lithium batteries for electric three wheelers. Vehicle OEMs, fleet operators and battery distributors need clear technical reference to pick cost-effective, safe battery packs. This industry brief covers cell types, standard specs, structural composition and market selection advice for global buyers.
1. Definition & Basic Parameters of Small Power Lithium Batteries
Small power lithium batteries, also known as LEV lithium batteries, refer to compact lithium packs for light electric vehicles, separated from passenger car traction batteries.
Energy range: 10Wh–500Wh
Standard voltage: 48V, 60V, 72V, matched with 250W–3000W motors
Discharge performance: Continuous 1C–3C, peak 5C–10C for climbing and full-load startup
Mandatory export certification: UN3480 for air & sea transportation, IP54 waterproof shell for outdoor tricycles
2. LFP VS NCM: Two Main Cell Technologies
Two mainstream chemistries dominate the small power lithium battery market, suitable for different two/three-wheeler scenarios.
2.1 LFP Lithium Iron Phosphate Battery
Single cell 3.2V; 16S for 48V, 20S for 60V, 24S for 72V.
Advantages: High safety, no fire risk under extrusion or puncture; 2000–3500 charge cycles, service life 5–8 years; no cobalt, stable raw material cost.
Disadvantages: Weak low-temperature performance, capacity drops sharply below -10℃.
Best use: Heavy cargo tricycles, delivery fleets, shared swap e-bikes, tropical markets.
2.2 NCM Ternary Lithium Battery
Single cell 3.7V; 13S 48V, 17S 60V, 20S 72V.
Advantages: High energy density, lighter weight, 20%-30% longer range than LFP; excellent low-temperature discharge.
Disadvantages: Shorter cycle life (1200–1800 times), higher thermal runaway risk, higher cost.
Best use: Household e-scooters, high-speed electric motorcycles, cold climate regions.

3. Standard Voltage & Capacity For Two/Three-Wheeler Batteries
48V lithium battery packs: 12Ah–24Ah, fit standard e-bikes and shared scooters, range 30–100km.
60V lithium battery packs: 20Ah–30Ah, match electric motorcycles and light tricycles, range 70–130km.
72V lithium battery packs: 25Ah–35Ah, for heavy delivery tricycles, range 80–160km.
A qualified lithium power battery pack includes 4 core parts: Grade A power cells, smart BMS protection board (overcharge, over-discharge, overheat & balance control), shockproof EVA foam, IP54 waterproof outer shell and high-current output plugs. Heavy-load three-wheelers need upgraded BMS MOS tubes to sustain large peak current.
4. Why Lithium Batteries Replace Lead-Acid Globally
Ultra-light weight reduces vehicle load and power consumption.
Longer service life cuts repeated procurement cost for delivery fleets.
Environmentally friendly, meets global carbon neutrality policies and export standards, no heavy metal pollution like lead-acid.
5. Scenario-Based Buying Guide For Overseas Buyers
Cargo delivery tricycle fleets: Choose 60V/72V LFP small power lithium batteries for long cycle and high safety.
Household e-bike distributors in cold areas: Pick lightweight NCM lithium batteries for electric two wheelers to avoid winter range loss.
Shared swap station operators: Standardized 48V LFP swap packs for unified maintenance.
High-speed e-motorcycle manufacturers: High-rate 60V/72V NCM packs for strong acceleration.
6. 2026 Market Trend
IEA data shows electric two and three-wheelers account for most global light EV sales. Two core trends:
LFP lithium batteries for electric three wheelers keep growing due to booming last-mile delivery demand.
Global safety regulations become stricter; only certified manufacturers with UN3480 can complete export customs clearance. Custom OEM/ODM battery packs are increasingly popular for local vehicle brands.
Conclusion
Small power lithium batteries are essential energy equipment for global light electric vehicles. Buyers must select LFP or NCM according to local climate and vehicle load demand, and verify complete BMS protection and export certifications to avoid after-sales risks.
