Is there power loss with 2nd batt in rear???

Nup. Just big fat cable. Fatter than your thumb should work nicely.

Im not sure of your situation but I know that in the ACT if you have a battery in the passenger compartment then it has to be in a special vented enclosure to prevent accident...in the event of someone smoking etc.

being an owner of a bitsarmissing Challenger, my dual battery sits in the back with all its mates (fridge, beer,spares etc) no worries. I have an anderson plug sitting tucked away for when I need the "Dual" battery . works a treat. wiring is such that it is charged when it is required etc.

From what I can gather Synergist as long as the wiring is heavy enough to carry the total current without any drop in voltage you should be right. Although venting can be an issue. Collyn Rivers has published some great books which cover these sort of questions."Live today as if there may be no tomorrow"

Sandie is spot on. If you intend to use it as a backup for starting the beast you'll need a wacking great cable. Try welding leads ... very heavy (thick) and flexible.

Make great jumper leads.

No probs as long as you use good cable and protect it from chafing etc. Use good quality cable from a car audio supplier, they can also give you the crimp on eyelets etc, the car audio cable is fine strand ofc copper and designed for the least voltage drop possible, use 4 guage or go to 2 guage if you really want to be a high current freak !! :-) OH yeah also make sure you put an inline fuse within 6 inches of the battery to protect the cable if it shorts to the body. you can get nice weatherproof wafer fuses rated up to 500 amps. And put the batt in a 'marine' box and vent it properly.Just killin time till easter...............go and play in the dirt, instead of workin in it......
