Marine and Backup Power PACKs
Lithium and sodium-ion PACK solutions for marine starting, energy storage, telecom backup and portable power.
View solutionWhy sodium-ion fits start-stop duty.
Start-stop batteries face short, frequent high-current pulses, winter cranking and cost-sensitive replacement cycles. NaVolt positions sodium-ion chemistry around those exact pressure points.
Long service life
Built for daily start-stop duty
More than 3,000 cycle life and over 100,000 simulated start-stop cycles help fleets reduce replacement frequency and lifetime service cost.
>3,000 cycles
Safety margin
Stable chemistry for abuse tolerance
The sodium-ion system is designed for no fire and no explosion in puncture testing, with BMS monitoring and safer 0V storage and transportation capability.
0V storage
OEM ready
Pack engineering from cell to system
NaVolt develops sodium-ion and lithium PACKs with model simulation, BMS matching, thermal validation and mechanical integration for export customers.

| Evaluation item | NaVolt sodium-ion | AGM / EFB lead-acid | LFP start battery |
|---|---|---|---|
| Cold start | Down to -45C target | Capacity drops fast below -30C | Often needs heating below -20C |
| Cycle life | >3,000 cycles | 300-800 cycles | Around 1,800-2,000 cycles |
| Start-stop endurance | >100,000 cycles | About 2,500-5,000 cycles | About 5,000-6,500 cycles |
| Abuse safety | No fire, no explosion in puncture test | Acid leakage risk | Thermal runaway risk under severe abuse |
| Storage and shipping | Supports 0V storage and transport | Heavy and acid regulated | Strict SOC and BMS control required |
