  • Dual Batteries

    Hey All Challenger owners,

    Who has done a dual battery system? I have tried to get a cradle, but have been told they wont do one due to the fact i have ABS (i though most did) and they cant access firewall on PS due to A/C underdash.

    They are very reluctant to place on inner guard as both TJM (who i am speaking to) and Pirahna say that most there have cracked the inner guard due to extra weight?

    What has everyone else done?

    Thanks

    Dave

    Can't say I have heard of that one. I have the tray from Opposite Lock that I think is a Pirhana tray in mine for two years now with no probs. The car had done it's fair share of 4wding as well. Not only is it bolted to the guard it has two brackets bolted to the firewall as well. So it has a fair bit of support.

      Tray

      Thanks Dave,

      I think TJM use pirahna as well, so muudy the waters become . Was just looking around net, and found your pics page, looks good! What battery are you running as the second? I havent even looked up behind airbag, is there plenty of room to get bolts in for tray?

      Thanks

        No need to do anything inside the cabin for the tray as it's all bolted in from under the bonnet. The tray sits on the lip on the firewall with two bolts and bolts underneath the tray to the guard. I have a Rotronics controller with a Champion Deep Cycle N50ex (550 cca 75ah)battery

          Dual Battery

          I have a Nov 2003 Challenger and purchased the Pirahna kit purchased through TJM. I fitted it myself with good instructions (included). You have to move the cruise control and charcoal filter. I run the OEM battery in this tray and I removed the black plastic anti splash protector and installed a Lifeline 105amp AGM in the original position. I had a auto elec install a Rotronics 2 stage independent battery management system as well as a 50 amp anderson plug for my camper trailer (120 amp AGM). All up I have spent lots but have been very happy with the complete system.

            And sounds like a good setup as well!

              Bit of a late reply I know but might be use to someone in the future. I have 98 challenger, no abs, and I fitted an opposite lock tray for mk triton. I had to trim it slightly to fit properly in places but nothing too dramatic. Fit seems very solid. It's only a small tray, 230mm length from memory, but I have made the auxiliary tray the starting battery, just had to separate the cables and manipulate them around a bit. So I have the auxilary battery in the standard tray, I'm using a supercharge allrounder, 120ah, been going well so far for 12 months. I have a redarc isolator and have the override wired to a momentary on switch on the dash so I can link 2 batteries for starting if required. Seems to work well.
