I have that for a long time already. I think the cause is because I have heavily rely on regen braking so my brake pads haven't been used for a long time and they become sticky. I purposefully press the brake on the highway to wear it down and then the next day the loud snap noise is gone. I...

Well, I thought you have dual battery system. But now I'm not sure anymore. I originally thought Rivian reroute the 12V system to use the primary as the source and have the super cap(because of the low impedance) in parallel with the primary to lower the surge current dip. But it seems it's not...

Looking at this chart, it seems the truck's voltage threshold for a float charge cycle is at about 12V. It looks like there was a surge current that momentarily pull the battery voltage down below 12V (probably due to the age of the battery causing a slightly higher internal impedance)...

Nice! That's a brilliant idea!

I'm very interested in learning how you have the gun case mounted on the side of the truck. Would you please elaborate?

I had these tires on my truck and the TPMS seems to work fine. I have them pumped to 60psi not 80psi though.

I also don't like to have the battery sitting at 100% for long. That's why for my road trips which needs 100% SoC, I'll adjust the charging schedule to let it just finish charging at around the time I plan to leave in the morning.

I tried running a 1000W microwave and it kinda work okay(heat things up slightly slower than having it plugged into the wall) at normal temperature. But the microwave won't heat when it's 20F outside.

The 16% usage from ABRP already has the elevation gain taken into account. So the rest of 7% is for battery preconditioning and cabin heating, well also assuming tire pressure etc are at nominal conditions.

Based on my last ski trip observation, the battery preconditioning stops at around 59-60F.

Do you remember the battery temp right before the downhill drive?

No, I don't think so. Maybe someone can correct me if I'm wrong.

Randomly picked a town roughly matching your detail here from ABRP shows driving ~33mile with an elevation gain of ~1400ft uses about 16% of the battery. That means your case shows heating up the cabin and the battery used about 7%. Using 16lbs per kwh for battery and thermal capacity of 950...

What does the "Battery Thermal Status" show? I'd like to know if battery temperature can be logged through HA.

I would not recommend doing this to save a few KWh due to the phantom drain issue. Having the chassis ground terminal removed could possibly cause low voltage circuit reliability issue. Even though you can still measure the battery voltage between the chassis and the positive terminal doesn't...
