Didn't take you long to tear into that Doug.

You should be able to squeeze those batteries in there.

Looking forward to the progress updates.

That's the idea see if I can get it to work, I don't think it's going to plow for to long though.

I think with the motor kicked back closer to the dash that you could get the 4 batteries in there with relative ease.   But then I've never laid a battery sideways in these frames either.

6 6 volts could work, measuring, the 12V would eat up a lot of space on that compact frame.

I need a 48 volt battery pack, could use 6 - 8volts batteries maybe. ???

I'm golf car based, so I mostly see 36v systems.

You use the 1275 Trojan batteries at all?

Sure do, they are pretty popular. Need measurements?

8 Volts are a good compromise if you can't get enough 6's in there, and need more energy density than 12's can provide.

 

There are, of course, other options available as well.  I've built things before with smaller "bricks" of 12v in multiple strings to provide the energy density required.  One such example is my old(er) racing scooter, which led me to win the scooter challenge in my local ev club a couple times.  I was in the 36v class, I wanted power for acceleration, as well as top speed, and also needed long range since the event was a combination of drag race, timed speed between a pair of traps, and maximum endurance.

That's two strings of powersonic high discharge rate SLA 12v bricks.

How do you charge the 8vt battery's, just charge them in series with a 48vt charger?

for 48 volt, you need either 6- 8volts or 8- 6volt batteries. 

 

Find yourself a used Ezgo or club car 48V charger. Typically those are for sale for $100-$150. Get an SA-8 Anderson plug for both the GT and the charger, will make life easier.
