Sodium-ion Battery Module
Uptime 24V 160Ah Sodium-ion Battery
Built for the cold, the Uptime 24V 160Ah Sodium-ion Battery replaces traditional lead-acid and lithium banks in security trailers, light towers, and other installations that live outside and must stay online year-round. It charges and discharges from -38°F to 138°F (-39°C to 59°C) and holds more than 85% of its rated capacity at -40°F. A 10,000-cycle life and the ability to fully recover from 100% discharge means more uptime with lower labor and equipment costs over the life of your system.

Benefits
Why Choose Uptime Sodium for Your Build?
Keep Charging in the Cold
Surveyed heated lithium products stop discharging at around -4°F. Lead-acid keeps discharging in the cold but gives up roughly half of its capacity doing it. An Uptime Sodium-ion Battery can be discharged down to -38°F and retains more than 85% of rated capacity at -40°F (-40°C).
Ultra Long Service Life
Uptime's sodium-ion chemistry, paired with a specialized battery management system (BMS), enables a 10,000-cycle life, measured at 80A charge and discharge, 85% depth of discharge, and 77°F (25°C), meaning fewer battery swaps and trips to the field.
Use the Full Rated Capacity
A lead-acid bank is sized at 50% depth of discharge, so you buy roughly twice the nameplate capacity you actually get to use. An Uptime Sodium-ion Battery can be taken to 100% depth of discharge and recover when it receives a charge, meaning a system that goes dark doesn't mean a replacement battery.
Fewer Points of Failure
One communicating module replaces a multi-battery lead-acid string, and up to eight modules connect in parallel for a maximum communicating capacity of 29.184kWh. Fewer parallel strings, good communication, cleaner cabling, and clearer service access can reduce field headaches.

Victron Integration via CAN bus and an internet connection provides access to historical and real-time battery health and performance data. Know the cause of failure before you make the trip, or avoid the trip entirely with this valuable information in hand.
Built to Live Outdoors
Designed for trailers and outdoor equipment that gets washed, splashed in mud, and parked in the rain, our IP67-rated enclosure protects against dust and temporary submersion. Included mounting feet, brackets, or straps secure it in vehicle, trailer, and stationary installations.
Drop-in Replacement for Lead-Acid Batteries
Two Ways to Measure a Battery Swap
By Energy Density
One standard group size GC2 or 4D lead-acid battery against one Uptime Sodium-ion battery, no footprint math involved.
| Battery | Energy, single unit | Weight |
|---|---|---|
| GC2 lead-acid, five-model average, 6V flooded | ~670Wh | 61.3lb |
| 4D lead-acid, 12V AGM | ~1,476Wh | 143lb |
| Uptime 24V 160Ah Sodium-ion Battery | 3,648Wh | 112.4lb |
That's about 5.4× the energy of one average GC2, at roughly 1.8× the weight, and about 2.5× the energy of one 4D AGM at 79% of its weight.
Published cycle life varies widely by brand and reporting method, roughly 750 to 1,150 cycles at 50% depth of discharge, against Uptime’s 10,000 cycles at 85% depth of discharge.
By Practical Replacement
How many Uptime units actually fit in the same enclosure space as the lead-acid bank they're replacing — and what you get for it, in both energy and weight.
| Configuration | Footprint match | Energy | Weight |
|---|---|---|---|
| 4× GC2 bank | – | 2,680Wh | 245.2lb |
| 1× Uptime 160Ah | 75% of the 4× GC2 enclosure | 3,648Wh | 112.4lb |
| 4× 4D AGM bank | – | 5,904Wh | 572lb |
| 2× Uptime 160Ah | 56% of the 4× 4D enclosure | 7,296Wh | 224.8lb |
In the GC2 footprint that's 1.36× the energy at 54% less weight. In the 4D footprint it's 1.24× the energy at 61% less weight. Fewer batteries, less wiring, several hundred pounds off the installed weight, and spare room left in both enclosures.
Questions buyers ask
Frequently Asked Questions
How cold can it charge?
Down to -38°F (-39°C). The Uptime 24V 160Ah Sodium-ion Battery uses the same floor for charge and discharge, so there's no separate colder discharge window to design around.
Where does the heater get its power?
In a solar-charged or lead-acid drop-in build, the 350W heating element runs on incoming charge current. It doesn't draw from the battery's own stored charge, and it doesn't run when no charge source is present.
How many modules can I connect together?
Up to eight in parallel with communication, for a maximum communicating capacity of 29.184kWh.
What maintenance does it need?
A full recharge to 100% state of charge every six months, which rebalances the cells and recalibrates the state of charge reading.
Can I monitor it remotely?
Yes. The battery reports over CAN bus at 250kb/s. With DVCC enabled, a Victron GX device becomes the active controller for charge and discharge and receives the reported values, and with an internet connection it passes that data to Victron's VRM portal.
