Dual battery?

[Jay3537]

When using my winch today on my 2020 powerwagon, the altenator and battery would not keep up. The battery light came on and everything inside powered down. eventually when left to idle for a couple minutes everything came back on. Is there a way to convert from single battery to dual on the 2020 PW? or how do you compensate for lack of battery reserve?

You could add a Tazer Ram module that has a winch mode which elevates the idle RPMs

It has a whole bunch of other options available that it's capable of

To my knowledge there's no such thing as "converting" from single battery to dual, it's just a matter of finding a place for it and running a couple wires.

how old is the current battery?

+ to+ -to- it’s pretty easy. i think the big thing is going to be where you can mount it. i would recommend looking at some big ram diesels that have 2 batteries to see how they do it. i dont know if the big diesels have dual batteries. i am sure someone will say. i think its definitely worth a look

i’m going to look at my 15 now to see what i can figure out

i know on 15pw there was a (spacer/tray)? i turfed it and i could run a bit bigger battery. i think the bigger tray is for diesel and the smaller is to save money on the manufacturer

Yes the Cummins trucks have dual batteries, one on each side of the engine bay.
May have to relocate some things to get the second tray in under the hood for the Hemi trucks. It's possible to even mount the second battery under the truck.
The op would also need to add a battery isolator and rewire the winch to run off the second battery. Probably still going to need to elevate the idle to get full current output from the alternator.

or a boat switch. i used to have a 84 chevy blazer. at the time it was our only vehicle and i would work out of town alot. we had two small kids and my son is autistic. the car had to start even at -40c. i could run off one battery or both or shut both off completely.

that blazer had two block heaters too
