2010 Challenger - Where to add second (house) battery?

[aviondubzz]

I have a 2010 Challenger 210 se and aside from mounting a battery on the opposite side of the starter battery I don't see many other options.

A smaller profile starter and house battery that will fit in the area where the original starter battery is?
Mount house battery under seat which is next to the starter battery and drill through for wiring?
A two in one starter/deep cycle battery?

I am in need of the house battery for an upgraded audio system.

Do you happen to have any pics? To me it looked like a tight spot to fit two batteries where the one stock battery is. Thanks

awesome, thanks for the pics. I will check out the tray you sent. Also, funny you mentioned the lithium, I was wondering why I have not seen any mention of them. I just switched to lithium on my jetski.

i mention lithiumFE cause it much lighter and much powerful and fast charging . In Canada we dont have starting lifepo4 or it cost 1K$ in USA you can get it for reasonable price

Yea the lithium are expensive. I was looking at this for a house battery (OPTIMA D31M)

Advance Auto Parts

Can I used any starter battery in conjunction with this battery?

You need to get special adapters which is switch between 2 batteries types

I wasn’t going to go with the lithium. I was going to do both starter and house batteries agm.

Unless I just use one optima battery that is rated as dual use both for starting and deep cycle.

Will this tray fit into a 2008 challenger 230se? I have a normal truck battery that I was going to put in and I would like to do this exact thing. Where do I put the ACR??

Thanks.

what is ACR ?

 

[memorx11]

what is ACR ?

Automatic Charging Relay, like they have in the Blue Sea Add a Battery kit. My understanding is that they will charge both batteries appropriately instead of one taking more than it should leaving the second battery without a charge.

awesome, just the inspiration I needed! What did you do with the battery cutoff switch up front? Did you swap to a dual battery switch or does the ACR take care of that for you? I am not great at visualizing. I am new to this!

Edit: How did you wire up the "house battery" to your accessories??

I added a second battery to my 2012 210 SP. I removed the current battery tray and built a platform out of trek decking and then mounted two group 31 battery trays to it. I placed them close together and turned them 90° to keep the bulk of the weight on the fiberglass battery platform. I also changed out the battery switch, added a relay to isolate the batteries and added a 2 bank battery charger. It was a pain in the ass, but it came out awesome.
