Dual battries setup on hayabusa engine powered car

[midgetll_busa]

Hey everybody,

i am in process to install two batrries on my hayabusa powered car, so i need the way how to wire these battries, my setup will be as following:

1- Denso 80 amp alternator will be used + the stock hayabusa engine stator for charging system.
2- external fuel pump will be usesd
3- dual radiator fans will be used
4- lighting system ( all lights are led)
5- sound system
6- electric reverse system using starter motor and flex plate type flywheel.

what is the best setup can i go with? And what is the recommended battries amp to be used in this setup. I think if i can wire all auxiliaries on the battery that charged directly from the 80 amp alternator or there is different setup and thoughts .
thanks in advance

The smart way is to isolate the one battery that runs the engine and then have accessories run off the other that's being powered by the alternator.
Id throw in an isolator that will also allow the Busa to charge both batteries but will cut off the accessory battery if it gets drained, thus leaving the power plant battery charged to run the engine.
Look at RV battery isolators to get an idea how they work.

Let us know how you like the electric reverse, I have seen a couple but never really had any reviews, is it good for more than just backing out of the trailer?

Hey Kuma, when ever i finish the fixture and fabrication work for electric starter i will post the process photos. Offcourse i will use this system for light loads such as reversing from trailer as you mentioned
