Pre-planned wiring pass-throughs for the winch?

"Ventilate well" suggests a cheap battery, not sealed ā¦ and is the battery in the same enclosed space as the cabin air filter?Definitely 2 12v batteries under there.
Shoot, forgot to check the filter. But it looks like this.

Yeah, that proximity of the 12v batteries to the cabin air filter is a little concerning. Anyone have other thoughts?"Ventilate well" suggests a cheap battery, not sealed ā¦ and is the battery in the same enclosed space as the cabin air filter?
I have vehicles where the battery is in the passenger compartment. It isnāt a problem for other brands, so not sure why you think itās a problem for Rivian?Yeah, that proximity of the 12v batteries to the cabin air filter is a little concerning. Anyone have other thoughts?

I guess I didnāt realize āventedā meant fumes were vented somewhere safe. I initially thought they were just vented at the top of the battery and could release fumes to that air intake.this is a vented battery, not sealed. not necessarily a problem.
My Miata had a vented battery and had a vent tube that attached and vented outside the vehicle.I guess I didnāt realize āventedā meant fumes were vented somewhere safe. I initially thought they were just vented at the top of the battery and could release fumes to that air intake.
I stumbled on your question in this year-old thread. I am very much interested in figuring out a winch solution, too. Have you learned more information since your question here, @Blueassassin?Do you see room for a winch to be mounted in the front? With the weight of this truck a large winch.
Nothing...I stumbled on your question in this year-old thread. I am very much interested in figuring out a winch solution, too. Have you learned more information since your question here, @Blueassassin?
see that CRF (Radiator fan) in the front??? it drwas air trought the condensor and radiator and out the sides.Am I seeing vented fender liners? Surely this isn't for aero since there's no exit path for the air... right?
Are you sure youād need an additional battery? I suppose if you wanted to operate the winch while the HV system is offline, maybe, but when the truck is āonā (aka, after youāve pressed the brake pedal), it should be using the DC-DC converter to bear the load, no?I posted some marked up images indicating where the winch is (apparently) meant to be installed. The two, small 12V batteries wouldn't power a winch, so there would need to be an additional battery. There's no access to the winch location, so it would need to be a WARN with remote control of the winch clutch (for free spool.) I think there's potentially sufficient space to "stuff" a battery under the frunk, away from the airflow through the radiator (which is a mess anyway.)
I wouldn't want to touch the already finicky 12V batteries. I'd rather have a beefy battery capable of dealing with the winch as a separate system and its own charger (again without connecting to the vehicle 12V.)Are you sure youād need an additional battery?

Rivianās configuration is such that each 12V battery is powering half the vehicle, so the maximum available to you is 13.6AH (136.2wH), and I canāt imagine that you could draw much instantaneously from a battery that small, and even if you did, it wouldnāt last long at all, as you said.
Even a 100-watt lighter socket accessory could be taxing on a battery of this size, and yet each one is rated for 10-amps, with separate fusing.
I guess my point is, you only would be taxing the batteries themselves if you were trying to run the Winch while the truck is not powered on. When the truck is on, you would instead be drawing from the DC-DC converter, just as the batteries themselves are. If you put the winch on its own circuit using an available fuse in one of the fuse boxes, and ensure youāre using a fuse that only works when the truck is in ready state, you should be just fine. Iād love to know more about the DC-DC converter and itās capacity for load, though.I wouldn't want to touch the already finicky 12V batteries.

I don't understand the "cost saving" (?) Rivian has pursued (e.g. limited 12/110V outlets, deleting the winch, etc.) I think it's still possible to get a winch in there with a sturdy cradle. Not sure where to get onboard power to supply a charger. It would be nice to have a 100A charger keeping the winch battery ready.
