Ive been doing a bit of looking as far as suitable relays go, but this idea works well for me because I will just put it in the trunk and then it will be perfect for stereo duties as well. If I use some xs power d925's Ill only be adding 20-30 lbs of battery weight but will have significantly more capabilities.
I like the idea of a charge-in-parallel / discharge-in-series system.

A few notes on you design:

-When the supercharger is in operation I'm pretty sure it will need to be electrically isolated from normal 12v/chassis-ground.

-DC solenoid relays of this size (36V / 200 Amp) as far as I can tell only come as single pole. I'll keep looking they may be out there. A different layout could uses lower voltage/current relays which come in STDT versions in parts of the circuit.

-Solenoid relays of this size are pretty expensive. So far what I've found start around $80 (x4 = $320) but better deals may be out there.


I hope you won't think I'm just criticizing. Overall I like the concept, I was trying to come up with my own but apparently my brain is only good for analyzing other people's designs at the moment.
