R1T Gen2 12v Battery Access

[ksumnole]

Greetings,

I'm working on replacing the oem "premium" subwoofer with a JL on a Gen 2 R1T.

Has anyone accessed the 12v battery terminals under the passenger seat? Any guidance would be highly appreciated. Thanks

I haven't, but I understand that the HV to 120v AC inverter is located there. Be careful poking around.

It's pretty easy to get to the terminals. Move seat back and pop off plastic cover. You have to remove the seat(remove bolts and tilt seat, not really remove it) to replace battery though. Can't say whats going to happen when you remove and re connect power though.

Thanks! Removing/tilting the seat back was easy. Now for the fun part...

Is that battery laying on it's side now? From this view it looks like a regular top mount SLA battery just tipped on it's side?

Definitely on its side. Can you get us the make and model of the battery?

 

[ksumnole]

Sure here’s another view.

Did you tap into it? Looking at doing that to add a 12v (cigarette) plug in the front.

too busy with work. Just had time to finish running the power wire to the amp location. Will try this week.

Please share when you do!

Have we confirmed that it's a SLA? Could it be LFP? The plastic bit on the top seems unnecessary unless they have a BMS for it in there. Having it inside the cabin also make a better case for LFP since its a little less exposed to elements and easier to heat.

Says Pb on top which stands for lead. I’d guess it’s still SLA

I’d honestly love someone that could post a video of accessing and tapping for accessory use

I googled that part number. Appears to be the same battery used in the G1. How in the world do they justify charging $600 for a $50 battery? Somebody please post the dimensions. I see no reason why we can't throw a LifePO4 in there when the warranty is up.

? we can always hope. LFP is the way to go. Switched my travel trailer battery over ...the only challenge is charging them when its below freezing...for that reason heating provisions are also needed. I understand why Rivian isn't doing it though.
