Battery Relocation Components

[No Crust Racing]

Interesting thoughts about the voltage drop Benny. If you read up, mine dropped SFA but I did use decent gauge wire.

yeah benny is onto something though. you end up with quite a bit of big heavy cable to ensure no voltage (or coltage in marlins case) drop. so he's probably right by the time you do all that weight increase would be in the order of a few kg. possibly better if you mount it in the cabin so you can shorten the cables. it will of course improve the weight distribution though being moved from the front drivers corner to the middle or rear of the car.

I weighed all my components (including cable) and saved less than 1KG over the big old battery it had up front. For me it was more so about moving a few KGs to the back of the car where the S13 is really lacking for weight. If it was a drift machine I wouldn't have bothered but I want it to grip not slide.

Removing all the AC was a bit more useful though as approx 14kg of the 17kg total that came out was forward of the front axle.

With about $10 in parts from Bunnings I finished off the battery relocation by connecting up a remote pull for the isolator switch. It comes up through the hole where the Aerial used to be. I've placed the battery triangle stickers accordingly.

Just got some stainless steel cable, a crimp for the end to stop it slipping out of the isolator key, some bits for the pull end so it basically has this sticking out of the Aerial hole. (not my pic)

I imagine it might need to be red or something for proper racing series but I think having the triangle stickers is enough for the track days I do.
