Remember, this is primarily a track car. Adding Lightness is a huge goal. Getting the battery in was pretty easy and cheap. no fancy boxes here. I simply rivited some aluminum angle to the floor to locate it. Then used a generic battery hold down bar to clamp it in to place. I also drilled some holes in the floor for drainage. Needed? IDK. But it made me feel better. 🙂
I chose a light weight Braille battery for obvious reasons. Not a lot of reserve, but I hope it doesn’t need much.
I also have a smart float charger attached. For a car that’s rarely driven, this is an important item. It’s not just a trickle charger. It’s keeps the battery in top shape without overcharging.
Connected to that is a master battery switch. It’s a 4 post design, controlling power to and from the battery and alternator. If the engine is running, it will kill the engine. IMO, an important safety device for any track car. It’s required by most racing organizations. Since I race TT it’s not really required, but suggested. I wanted it close to the battery, but also needed to be able operate it from the driver’s seat. I had to make this simple handle for it.
I seriously considered a very light weight Lithium-Ion battery. a battery that only weighs a couple of pounds looked really enticing. But I didn’t for a variety of reasons. Something big enough for a V8 was very expensive. And I still have some concerns about putting one together with a standard GM alternator. I’m not sure the technology is quite there. And then there’s the fire hazard thing.
