So for my system build i am going to be taking out the stock battery for 2 XS power batteries. this is going to require me to cut out the stock battery tray and make a secure tray for the 2 new batteries so they will be next to each other under a peice of plexiglass.. i know that welding around electronics is something that should be avoided at all times.. so my idea is to use JB weld to secure my new battery tray to the trunk bottom. what do you guys think, or would there be a better way?

 

I'd JB weld....you don't want to accidentally cut away part of your trunk with the welder LOL. But if you're a good welder go for it, there's not too many electronics down in the spare wheel wheel other than the battery cable, the clamp, and the tail light harness..

 

i can weld just about everything, i wasnt sure about stray voltage getting to the ECM/PCM/ or any computer for that matter

i really wanted to TIG weld this to make it a nice and clean upgrade, at most i would just do a 1/2" tack on each corner.

 

I'd look to find some way to reinforce the tray first (maybe with brackets/bolts/screws) before the JB weld. That stuff is strong, but it does not hold well in circumstances where there can be torsional stress across the narrow face of the repair, since it does not flex. Or, if you put a bit of light gauge metal overlapping the repair underneath and/or on top, thoroughly roughing the surfaces and JB weld/clamping the whole schebang together - that would give a greater surface area for the JB to clamp and reducing the torsional stress.

I've cracked a few repairs that I though would be a lot stronger because of that. It works great on rigid surfaces with cracks, but not necessarily a full cut!

 

it doesnt make a difference not much going on in the wheel well that you cant blatantly see.

i dont have any pics of just my tray but is just some angle iron welded together and screwed to body. initially the screws were for removal but its since been spectrum-ed over

 

heres the only full pic i got and it doesnt show much

 

Thats exactly what I was going to do with 2 XS power batteries!

EDIT: Is that a hinge to get to your batteries?? If so im going to do that too, if not well...still going to do it lol

 

also theres a gas tank underneath..

 

The gas tank is in front of the rear "axle". I would weld. As long as you really know what you're doing and have a good clean ground path you wont have anything to worry about as far as the ECM and such.
