The Ohmmu 12V LiFePO4 battery is lighter, more efficient, has higher usable capacity, and lasts 4x longer than the OEM battery from Tesla. It is a drop-in replacement to the Tesla OEM Battery (No firmware changes are needed). Long-time Model Y owners tell us that the original OEM 12V lead-acid batteries for their vehicle can be a weak point. They have been known to fail unexpectedly. When that occurs, your Model Y is immobile until the 12V battery is replaced. Our 12V Lithium Battery for Model Y provides you with increased durability, longer-lasting reliability, decreased weight, higher capacity, and better 12V performance. In addition, this better performance yields improved LED & Audio (higher nominal voltage, no voltage sag). Finally, these high tech batteries yield less environmental waste (fewer batteries being used and less material in each battery) and Increased efficiency (charge and discharge at a higher efficiency than OEM).
