Sodium-Ion Battery — Telecom & Starter Solutions
Sodium-ion (Na-ion) is a chemistry we offer alongside LiFePO4 where temperature or shipping drives the design. It keeps more usable capacity in deep cold, discharges without a heater, and a cell can be shipped at 0 V. For sites and vehicles where winter is the constraint, that changes the maths. We manufacture both and will tell you which fits.
Two Sodium-Ion Products
12V & 24V Sodium-Ion Starter Battery
- Cranks to -40℃ without pre-heating (800/1000 A peak)
- >6,000 cycles @ 80% DOD; ≥100,000 start-stop cycles
- Ships and stores at 0 V — simpler air/sea freight
- JIS and DIN footprints; UN38.3, cells to UL1642 / IEC62133-2
Why Sodium-Ion, and When
Sodium is not a straight upgrade over lithium — it trades energy density for temperature behaviour and shipping simplicity. The table below is how we frame the choice with operators and fleet buyers.
| Attribute | Sodium-Ion | LiFePO4 | Lead-acid |
|---|---|---|---|
| Cold discharge | Full at -20℃, no heater | Reduced; heater draws power | Severe loss |
| Cycle life | 4,000–6,000 cycles | 6,000+ cycles | 300–500 |
| Energy density | ~80 Wh/kg (pack) | Higher (~150 Wh/kg) | Low |
| Shipping / storage | Ships at 0 V | State-of-charge limited | Leak / sulphation risk |
| Best for | Cold / remote sites, cyclic start duty | Tropical / general, dense packs | Legacy only |
Pick sodium-ion when winter capacity or heater power draw drives your design. For temperate, density-sensitive systems, the LiFePO4 48V telecom pack gives more kWh per kilo. Both are in the Battery & ESS hub.
Typical Applications
Cold-climate BTS
Unheated cabinets and alpine sites where heater power or maintenance is the constraint.
Off-grid solar BTS
Deep daily cycling in unheated enclosures.
Vehicle starting
Cars, motorcycles, trucks, construction equipment and marine — reliable cold starts.
Seasonal equipment
Gensets and backup plant that sit for months, then must start.
Spare-unit fleets
Held at storage voltage, commissioned when a site needs them.
Frequently Asked Questions
When should I choose sodium-ion over LiFePO4?
When winter performance and lifecycle cost drive the design. If your sites see months of sub-zero temperatures and you are budgeting heater energy, heater maintenance or winter capacity derating, sodium-ion is worth evaluating. If the site is temperate and you are optimising for cycle life and energy density, our LiFePO4 range is the better fit — we make both and will say so either way.
Is sodium-ion safe to ship?
A sodium-ion cell can be discharged to 0 V for transport, which removes the state-of-charge limits that apply to lithium in air and sea freight. UN38.3 test documentation is still required — we provide it with the shipment.
Can a sodium-ion starter battery replace lead-acid directly?
In most 12 V and 24 V systems yes, provided the charging system's voltage window is compatible. Sodium-ion has a different voltage curve from lead-acid, so we recommend checking the alternator regulator set-points with us before a fleet-wide swap. We supply the charging profile for your platform.
