Jump Battery Recommendations

[kyunam]

I have G1 R1S with two 12v batteries.
What proper jump batteries are out there I should consider buying?

Thanks!

Hey there. So Rivian has some requirements and while I have not tested this jump pack it should work based on what I am reading. I am going to pick one up to keep with me. The jump pack needs to provide power long enough for the truck to boot which some of the small ones do not.

This is basically what Rivian uses. A Smaller jump pack might be only good to open the doors and that's it (I have a NOCO GBX75 that was good only for this).

1) Where are y'all storing these things?
2) If the jump pack uses standard Sealed Lead-Acid batts, they will probably be dead when you actually need it. These packs need to be recharged frequently.

IMO, there is really no good solution for the dead 12v battery jump issue unless it happens in your driveway.

1) I have it in the frunk (just the small Noco) and I have a hidden box in the trailer hitch with tools to get the Frunk open in case of (another) 12V dead situation.

2) True, I would only get/use one of those big jumpers if I'm going on a Road trip where access to a flatbed truck or something along those lines would be difficult to get, and in that case, I would top-off the jumper before the trip begins.

I've got an untested solution that I hope would work if needed. I've got a 12v 50ah LifepO4 battery in the bed of my R1T that is powering a 12v fridge 24/7. I currently keep it charged up via a battery charger connected to the 120v outlet with the outlets set to auto (so it tops off the battery when I'm driving, but allows the R1 to go to sleep when I'm not), but my eventual goal is to mount a solar panel over the bed and keep it charged that way. I then ran a cable from the bed down to the jump wires in the hitch (very easy to do in the R1). Those wires are not connected to anything in the hitch, but the idea that in a pinch I can simply pop open the hitch cover and connect the wires from my LifepO4 to my jump wires which in theory should allow me to power up the R1 to be able to open the doors and get inside and hopefully start driving. If my 2nd battery was also dead, I could in theory access both batteries and wire my LifepO4 to both dead batteries and maybe get going again. All this is pretty impossible to test, but at least puts me in a better chance of getting moving again if I'm off grid somewhere.

For T owners could keep in rear under seat storage. For R1S could keep in spare tire area provided you have no spare in there. Set a reminder to pull it out periodically and top off charge.

Seems a good preventative as opposed to having a tow operator try and tow a bricked truck.

But how do you get in to the vehicle to retrieve the jump pack if the 12V batt is dead?

Frunk maybe the better place since you can manually open..?

Yes, but you need tools in order to remove some trim inside the wheel well to get at the manual frunk release pull cable. So, where do you store those tools?? Lol, yes I know some store the tools inside a ziplock bag inside the trailer hitch receiver, but lots of people use the trailer hitch, so that rules out that area for tool storage. As I mentioned earlier.. no good solutions to storing a large jump pack, unless your Rivian dies in your own driveway.

It's amazing how little thought Rivian gave to something as simple as frunk access considering the 12V batteries live under there, and you need 12V power to access it

i guess Rivian didn’t think of this scenario when they designed it. I think with Tesla 3/Y you can use a small battery to pop the trunk and get access to 12v.

Realistically, I would only take the jump pack with me when I was on a trip and in that case, I would remove it from the vehicle when I was away from it.

should be a way to manually pop the trunk to get at the 12v without having to fully power up the vehicle.

yeah chicken or egg situation ..

Yup, and it's probably something they regret not fully addressing considering how many dead 12V battery incidents there have been.

If you are planning to carry around a giant jump pack may as well just carry replacement batteries instead. If my batteries weren't just replaced These seem tempting https://a.co/d/4DhEeQn

You know what would have solved it? A key, even if was to frunk/tailgate only! ?
