Getting to the stage where I am about to start the electrical on my KF 5 build. The manual calls for the battery on the inside of the firewall. The newer models are on the outside and I have seen a KF 5 on you tube with it on the outside. I think I would be able to mount it either way. Looking for thoughts/advice on this. Any pros or cons either way that anyone has run into? Right now I am probably going with an odyssey battery so weight would matter.
