More power

Ok Guys
How about using 6, 12 volt batteries 3 each in series and then the two banks of 3 batteries each in parallel ending up with 36 volts. Will it work?

You could definitely do some arc welding with that much juice.
It will make 36 volts. I don't know how it will perform on your bike.

Yes it will work, just do the amp hour math to calculate your range.
