Best 12V 100Ah sodium-ion batteries
Researched by Deal.ai's shopping agent across stores on November 2, 2026. Prices below are today's.
Top pick: the Ohmmu Energy Group 31 100Ah 12V sodium deep-cycle. It's the one that drops into a normal RV 12V system without a converter or series wiring, and sodium-ion's big win over lithium is cold-weather tolerance and a less flammable chemistry — useful for a rig that sits through winter.
Who the others suit:
- 48V/51.2V 100Ah packs (JMBatteries): for a dedicated solar bank or power wall, not a 12V RV house circuit.
- Stackable and wall-mounted versions: when you're building capacity over time or mounting indoors.
- All-in-one wall unit: if you want the inverter and battery in one box.
Check each listing's BMS amp rating against your inverter's draw before buying.
