Sunwoda 139AH 3.2V LFP Lithium-ion Prismatic Battery Cell

Core Applications
New Energy Commercial Vehicles & Construction Machinery Power

Suitable for heavy-duty, high-cycle operation scenarios including electric buses, heavy-duty trucks and construction machinery. Its high-rate discharge performance stably supports heavy-load climbing and frequent start-stop operations; ultra-long cycle life significantly reduces total lifecycle cost, and fast-charging capability ensures operational efficiency.

Energy Storage System (ESS)

Widely used in grid frequency regulation & peak shaving, telecom base station backup, commercial & industrial (C&I) energy storage, and residential energy storage. With 3,000–6,000 deep cycle life, excellent thermal stability and cost advantages brought by mature supply chains, it has become the mainstream technology in the global energy storage industry. Large-format prismatic LFP cells such as 280Ah and 304Ah have been widely deployed in benchmark energy storage projects worldwide.

Electric Two-Wheelers & Light Mobility Devices

High-capacity LFP large-format cells are mass-applied in food delivery scooters, shared e-bikes and long-range commuter vehicles. With 3–5 times the cycle life of traditional lead-acid batteries, they deliver outstanding cost performance and easily meet daily commuting and high-frequency operation demands.

Low-Speed Sightseeing Vehicles & Off-Road Utility Vehicles

Ideal for in-venue vehicles like scenic sightseeing buses, factory shuttles and golf carts that prioritize cost and durability. LFP cells feature long service life, low cost and high safety, which greatly reduces operation and maintenance costs.

Electric Ships & Yachts

Inland cargo ships, sightseeing yachts and watercraft have extremely high requirements for safety and durability. LFP cells offer strong thermal stability, non-flammable and non-explosive properties, combined with long cycle life, greatly reducing safety risks and operation costs in marine scenarios.

Industrial Robots & Logistics AGVs

Warehouse logistics AGVs, industrial robots and service robots require long-hour high-frequency operation. LFP large-format cells feature long cycle life and high reliability, reducing battery replacement frequency and improving continuous operation efficiency of equipment.

Starter & Backup Power Supply

As the core alternative to lead-acid batteries, LFP cells provide longer float life, lower self-discharge rate and excellent safety performance. They are widely used in automotive jump starters, data center backup power systems and base station backup power supplies.

Technical Suitability Scope
Long Cycle Life & Cost-Effective Scenarios (3,000–4,000 deep cycles at cell level) Delivers significant total lifecycle cost advantages, suitable for large-scale high-frequency charge-discharge applications such as energy storage, commercial fleet vehicles and shared equipment.
High Safety Requirement Scenarios Excellent thermal stability, resistant to decomposition and combustion at high temperatures. Ideal for applications with strict safety standards such as passenger buses, energy storage, densely populated areas and marine operations.
Medium-to-High Rate Charge & Discharge Scenarios Supports 1C–3C continuous charge and discharge. Suitable for ride-hailing fleets, logistics fleets and heavy-duty construction machinery that balance range and power demand.
Wide Operating Temperature Range Operating temperature: -20°C to 65°C, with outstanding high-temperature performance; approximately 60% discharge efficiency at -20°C, lower low-temperature performance than NMC. Strong adaptability in high-temperature environments; active heating is recommended for charging below 0°C.
Long Standby & Float Backup Scenarios Low self-discharge rate and long float service life. Perfect for backup power, UPS and base station standby power that require long-term standby and occasional discharge.
Large-Scale Cost-Sensitive Scenarios Abundant raw material reserves and mature, stable supply chain. Lower procurement cost per capacity than NMC, ideal for large-scale deployment projects such as energy storage, commercial vehicles and entry-level passenger cars.
BMS Protection Requirements Supports overvoltage protection (3.65V cut-off), over-temperature protection and cell balancing. Effectively prevents overcharge and over-discharge risks, ensuring cell consistency and long-term stable operation of large-format battery packs.
Non-Ideal Scenarios Scenarios where extreme lightweight and maximum energy density take priority over cost and safety. Examples include high-end long-range passenger vehicles, aircraft and lightweight portable devices — NMC is generally recommended for these use cases.
