Oh ok. I thought this was a 12volt battery thread… that would be low voltage/standard battery. Yeah mine is in my frunk too. You dont need the Tesla brand battery, just the correct size 12volt from any store. Just my experience…I think the Model 3 battery is a lot easier to get to versus the S and X. They are telling me it is a high voltage battery and Tesla Tech is the only one that can replace it. I think b/c it is hidden in the Frunk.
