Thread: dual battery hook up

Tweet

Instead of two batteries I would suggest this one battery. Look at the specs below, it even replaces an 8D battery that is used in trailer trucks and yachts!!

I am using their SMALLEST battery that they make for BMW motorcycles, and it starts my 350 Chevy like gangbusters. This group 31 would crank even a fuel dragster and is very compact.

interesting battery Don...i had to parallel two small gel cell batteries in my coupe...just behind the seat...gas tank is in the trunk and theres very little room between the tank and the back of the seat

The guys are right, one big battery is better. Two are only as good as the poorest one, and the extra connections are a headache. If space makes it necessary, pay special attention to all connections, keep everything bright and shiny.

Guys, thinks for the info...I have a 468 BB and it seems to be a little
hard to start when it's hot, plus the electric fan, and fuel pump has a
draw on it. I am currently using a long Interstate, don't even know the
amp size, but I think you have convinced me to stick with just one battery
to eliminate weight and confusion....rdobbs
