Thanks

Thanks for all of your replies its given me a lot to think about. I now understand how to get the tie down points in using rivnuts.

Would one of these suit what you have in mind?

How would you instal it? I assume you'd still need some sort of tray.

Any chance of some photos & a description.

I've been looking at the devon 4x4 tray, suitable for 2x Group 34 size batteries (similar to the optima).
From what I understand, the pirahna tray retains the stock battery, which is huge (I plan to run all battery control gear within the battery box).

Toxic_Avenger,
I've used a Century deep cycle, N70T.
306x171x222 (LxWxH)
I went for this as I have an old car fridge which is a little less efficient than the newer ones and this battery is 100 AH. However, it is wet cell and if I was buying again I'd at least get maintenance free which are sealed better. AGM and GEL also seem good (if not excellent) but start costing more.

Size wise, height is the main problem, trying to avoid contact with the compartment cover. Because of the shape of the compartment, the shorter the battery, the more height available. I spent some time in Battery World, and auto shops measuring various batteries. In the end its all a trade-off between, AH, physical size and available funds.

Hi Loneranger,

here is the link to my dual battery install - it may give you some ideas/options.

Dual Battery Install - 2013 110

My installation required the replacement of the original LR battery, and the installation of two Optima's.

I also used Tim's excellent USI-160.

Anyhow, have a look and hope it might help.

cheers,

Wayne

I'd read your thread previously before I started playing with my set-up so a lot of it went over my head. At least I now know what that thing hanging off the +ve terminal is and how to extend the battery cable.

I'm going to go with an Optima yellow-top for the deep cycle so I'll get that then explore my options for fitting it now I have a better understanding of how it all works.
