Off-Grid Sodium Ion Battery
What are Off-Grid Sodium Ion Battery?
- To meet the needs of “off-grid power, plug-and-play, and worry-free power,” we’ve integrated prismatic sodium ion cell and a smart BMS, based on extremely safe sodium-ion battery technology and advanced BMS technology, to build an advanced and extreme safe Off-Grid Sodium Ion Battery.
- In 2026, There are two versions of the Off-Grid Sodium Ion Battery, they are 12V160AH sodium ion battery and 24V160AH sodium ion battery.
- This product is primarily designed for space-constrained, off-grid scenarios where power is essential, such as small boats, RVs, Campervans, and mobile power devices.
- The biggest advantage of the Off-Grid Sodium Ion Battery is its ability to directly replace “unsafe lithium batteries” or “toxic lead-acid batteries” without requiring a charger replacement.
Why chose Off-grid Sodium ion battery?
- Safest NFPP SIB technology, never fire nor explosion
Based on sodium Ion battery technology,Off-grid Sodium ion battery are made of 160AH NFPP Sodium Ion Prismatic Cell, this mass-produced and needle-punched smokeless cells have fully passed rigorous safety testing,no risk of fire or explosion
- Advanced BMS technology, double safety and performance.
The 12V160AH Sodium ion Battery and 24V160AH sodium ion battery, both integrated battery management system (BMS) , along with safety switch. The BMS directly controls the sodium ion battery’s output, and the internal switch automatically disconnects the battery output in the event of overcharging or a short circuit. It supports 1C fast charging and 160A high-current output, and also features Bluetooth.
- Easy replacement for lithium-ion or VRLA batteries
Its standard form factor allows it to be directly installed in most lithium-ion or lead-acid battery mounting locations. Wiring is the same as for lithium-ion/lead-acid batteries—positive and negative screw terminals—requiring no changes to charger settings or communication cables.
- Flexible configuration, You can in parallel it or in serial
Maximum 6 PCS *12V Sodium ion batteries can be connected in series to form a 72V off-grid sodium ion battery system, or 4 PCS* 24V sodium ion batteries can be connected in series to form a 96V system. Although there is no limit to parallel connection, parallel + series connection is not supported.
- Ultra-Low self-discharge , 2 years shelf life without charging
The self-discharge rate is less than 0.7%/Month, which ensures both BMS and modules extra low power consumption during long-term storage, and double ensure the longest shelf life of 12V sodium ion battery or 24V sodium ion battery

Use Notes
- Charger Settings
Charging voltage is typically 14.2V (12V system) or 28.4V (24V system), with a recommended float charge voltage of 13.5V/27.0V. It can be used in lead-acid battery mode or switched to lithium battery mode.
- Series + Parallel Connection Not Supported
Off-grid sodium ion batteries of different capacities and states of charge cannot be connected in series or parallel. When connected in series, all batteries must be of identical model and have the same state of charge (SOC).
Our understandings regards to 12V battery or 24V battery
- Traditional 12V and 24V, whether it is VRLA battery or Li-ion battery, both come with limitations, such as shorter lifespans, longer charging time, lower output power, higher warranty costs and TCO, and an ongoing environmental burden. We have been told many times that battery can not be used in extreme cold weather or extreme hot weather, because cold weather significantly impairs battery’s performance, or hot weather will accelerates self-discharge and It could lead to shorter service life, however, it is during these hot or cold season that more energy is needed for use.
- We believe the future trend of off-grid battery, whatever it is 12V battery or 24V battery, it is about more than getting from VRLA Battery to Li-ion Battery, or nor Li-ion battery to Sodium ion battery, it’s about providing right battery for use in anytime, anywhere, so it is very safely, strongly, sustainably and with confidence in your energy source. Therefore, we develop off-grid sodium ion battery, 12V160AH Sodium ion Battery and 24V160AH sodium ion battery to power any time, any time, mostly importantly, power free.
- 12V sodium ion battery and 24V sodium ion battery are cost-effective top choice for off-grid scenario, where power needs. With abundant, non-monopolized sodium resources, its raw material cost is only 1/50 that of lithium batteries, and can drop another 5%-10% after large-scale production. Therefore the price will never increase.
- 12V sodium ion battery and 24V sodium ion battery are not only cheap, but also very safe, due to NFPP sodium ion battery technology,its initial thermal runaway temperature is more than 200℃，which means battery will never face the challenges of fire or explosion, even it is under extreme abuse. Not at all, It also supports fast charging, you will wait just 15 minute so that the battery will be charged from 0% SOC to 80% SOC, along with more than 15000 cycles, it can be used in anytime, any where.
Why off-grid sodium ion battery is strong and robust?
