48V. Traction-Grade.
Drop-In Ready.
Sodium-Ion NFPP | 48V / 300Ah / 14.4 kWh | 6,000+ Cycles | −20°C to +45°C
A complete 48V traction battery system engineered for electric mobility applications — golf carts, forklifts, airport ground support, AGVs, and campus vehicles. More capacity and 50% higher discharge current than the Series-R, with rugged IP54 protection and sodium-ion chemistry that eliminates thermal runaway risk in enclosed vehicles.
Complete Traction Battery System
Everything You Need. Nothing Extra to Source.
The 48V Series M ships as a complete, ready-to-install traction battery pack. Rugged IP54-rated enclosure, integrated BMS, standard 48V terminals, and 150A continuous discharge — a direct drop-in replacement for lead-acid traction batteries.
-
Sodium-Ion NFPP Prismatic Cells (16S2P)
Non-flammable, non-toxic sodium-ion chemistry — zero thermal runaway risk. Safe for enclosed vehicles including forklifts, golf carts, and airport tugs operating in warehouses, garages, and passenger areas.
-
Built-In BMS — 8 Intelligent Protections
Real-time monitoring of overcharge, overcurrent, overdischarge, overheat, temperature, short circuit, balanced power, and reverse connection — continuously protecting cells and the vehicle's power supply.
-
IP54-Rated Rugged Enclosure
Dust-protected and splash-resistant IP54 enclosure (790 × 520 × 210 mm) built to withstand the vibration, shock, and moisture exposure of daily traction use in industrial and outdoor environments.
-
Standard 48V Terminals — Direct Drop-In
Standard 48V battery terminals allow direct replacement of existing lead-acid traction batteries with no wiring modifications. Works with all standard 48V chargers and vehicle controllers.
-
150A Continuous Discharge — High-Power Traction
50% higher continuous discharge current than the Series-R, delivering the sustained high-current output required by forklifts, airport ground support equipment, and heavy-duty utility vehicles.
Why Sodium-Ion for Electric Mobility
Where Lead-Acid and
Lithium Fall Short,
Sodium-Ion Delivers.
Lead-acid traction batteries require regular watering, equalization charges, and degrade rapidly under deep cycling. Lithium-ion carries thermal runaway risk — a serious liability in enclosed vehicles and passenger transport. The 48V Series M eliminates all three problems with sodium-ion NFPP chemistry: maintenance-free, non-flammable, and built for 6,000+ deep cycles.
Sodium-ion NFPP chemistry is fundamentally non-flammable. No thermal runaway, no toxic gas emissions, no fire risk — safe for enclosed vehicles, passenger transport, and indoor warehouse operation.
- Zero thermal runaway incidents to date
- Non-hazardous shipping — air-shippable
- No toxic gas emissions in enclosed spaces
- Safe for passenger-carrying vehicles
Operates reliably from −20°C to +45°C with no thermal management system required. Performs in cold storage warehouses, outdoor environments, and high-temperature loading docks without derating or performance loss.
- −20°C to +45°C operating range
- No HVAC or active cooling required
- Minimal derating at temperature extremes
- Vibration and shock resistant (IP54)
No watering, no equalization charges, no acid spills. The Series M is a true drop-in replacement that eliminates the ongoing maintenance burden of lead-acid traction batteries — reducing downtime and total cost of ownership over a 20-year design life.
- No watering or equalization required
- Fast charging capability
- Works with standard 48V chargers
- 20-year design life at 25°C
