8 volt battery usage

Hi guys , I know I'll get blasted for going to an 8 volt battery, but hey it starts like a brand new car.. I was worried about the 6 volt radio ( bone stock 55 country sedan ) so I wired in a 15 amp capacity buck converter and adjusted the output down to 6.2 volts to the radio , seems to work as expected. But the i got thinking (dangerous ) why cant I wire it into the yellow wire at the solenoid since it seems to be the main if not only power feed off the battery , effectively controlling the feed to everything to 6.2 volts ? I'd be interested in your thoughts... Thanks Fred
 
If you are running incandescent lights, I would calculate the load. 15 amps might not be enough
 
ff, not a blasting at all for going to an 8 volt battery, but for the effort you're putting in, you could have fixed the problem with the original 6 volt or have bitten the bullet and gone all the way to 12 volts.

I don't understand you thinking!!
 
Question for the OP. Is the wiring old?
Have you tried 00 size wires to the ground and starter?
We did this for the battery cables with an 6V Optima. It cranks fast and starts right up.

fast fredy, it's true. All of the battery and starter Ground cables must the correct larger size, at least "1" or preferably "0" gauge (or larger). Not generic battery cables from the corner parts store.

With very clean and appropriately tightened connections. Any corrosion or loose attaching hardware will cause problems.

Same question on another forum, got the same answers as here. Better try a 3rd forum and maybe you will get the answer you are looking for.
 
The 8-volt battery works well in golf carts that run on 32-volts. Many have gone to higher voltages in the modern era. For cars, it's just easier to go to 12-volt. It also makes a lot more sense if a person does a lot of long distance driving.
