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.

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