Hellroaring Technologies

I too am looking into a dual-battery setup for my 2003 Discovery.

My main desire is to have a backup battery always available to start and operate the vehicle if the main battery becomes discharged (which has happened twice to me in the past few years).

I'm looking at getting a "Hellroaring Battery Isolator/Combiner (part #BIC-95300B)" from Hellroaring Technologies, inc. ( and running two Optima D31M Blue Top Batteries.

I need to do a bit more research and also look into figuring out the installation (I'm not even sure there is space for such a setup under the hood).

If anyone has experience with Hellroaring or knows of any existing battery trays for dual-battery setups in a Discovery, drop a note.
