Upgrade your Toyota Prius 12V battery with a Lithium Iron Phosphate (LiFePO4) battery from Ohmmu!

 

The Ohmmu 12V LiFePO4 battery is lighter, more efficient, eco-friendly, has a higher usable capacity, and lasts 4x longer than a traditional sealed lead acid (SLA) battery.

 

ATTENTION: Our current Toyota Prius Gen 1-3 battery has a reverse terminal orientation from OEM (positive on the front right, negative on the front left). Depending on the battery position used for the install, this may require the positive and negative cables to cross over one another, and/or cable management clip(s) to be removed in order for the battery cables to have the proper reach to connect to their corresponding terminals.

•  4 Years Full-Replacement Limited Warranty

•  Proprietary 12V Lithium cell and BMS technology that is a drop-in replacement to your existing battery (no firmware changes needed)
•  Battery Management System (BMS): manages cell balancing for a long service life and protects your battery from high/low voltage, overcharge, high/low temperatures, and short circuits.
