Power your Rivian adventures with the new High-Performance BT19 Sodium 12V Battery from Ohmmu - which has been engineered to be compatible with the Rivian R1S and Rivian R1T.
Designed as a direct OEM replacement, this advanced Sodium Nickel Chloride Battery (a blend of NaNiCl2) delivers greater efficiency, durability, and performance than traditional sealed lead-acid batteries—while requiring no firmware changes or modifications during installation. Built for modern EV systems, the Ohmmu 12V battery offers higher usable capacity, improved electrical stability, and significantly longer lifespan—up to three times that of conventional lead-acid batteries. This translates to more reliable accessory power, better voltage stability for electronics, and fewer battery replacements over the life of your vehicle.
Weighing just 6 lbs per battery, the lightweight design improves efficiency while maintaining robust performance.
The battery is compatible with both single-battery and dual-battery Rivian configurations, accommodating model changes introduced around March 2023. Earlier builds use dual 12V batteries, while newer builds operate with a single battery alongside a capacitor system.
With Climate-Proof Sodium Cells, it ensures reliable charging and operation in extreme weather environments. Backed by a 3-Year Full-Replacement Warranty, the Ohmmu battery provides peace of mind and long-term reliability for Rivian owners seeking a premium low-voltage power solution.

*ATTENTION
Rivian changed the 12V system with new builds released around March, 2023 and later, to utilize a single 12V battery instead of dual 12V batteries on previous builds. On newer builds, the passenger-side unit is a capacitor (NOT a 12V battery), and now only requires a single 12V battery installed on the driver-side.
Prior to ordering, we recommend you inspect the left (passenger-side) 12V unit of your vehicle to confirm which version you have. If the left unit's passenger-side terminal is black (negative), then it is an earlier build with dual 12V batteries. If it instead has a red (positive) connection there, then it is a newer build with a single 12V battery (capacitor on the left, 12V battery on the right / driver's side).
