Anybody thinking about the LI  (Ballistic) batteries. Their power and specs (2-4Lbs) seem too good to be true. Apparently they have solved the fire problem plaguing cell phone and computer batteries.

 

Starting should be no problem. I do wonder about their, as well as AGM,  capacity in the case of Alternator failure. (time with power)

 

Am knee deep in wiring as I write this. Trying to decide on dual alternators.

 

The rotaries are hungry for electricity (EFI, EI, fuel pumps, etc).

 

My primary alternator is the standard Renesis 100A type. I will externally regulate it. The aux, --unknown --possibly a 20A B&C, I have their aux that fits into the vacuum drive.

I used Odessy (sp?) AGM type batteries.  17 AH in the -4, 28 AH in the -8.
