I kinda like the big 48 volt idea no loose connections, why not even a 60 volt unit better top speed when using a 48 volt motor.
its not one battery vs the other its the total Ah of the pack, off the top of my head its something like 15% more with the 6 eights, I have 4 twelves in mine and I do not push them anywhere near there limits so this works great for me, now if you are always running low then you either need new batteries or you need to switch to 6 eights figure out how man miles you need to travel and work from there.
