Hater, I'll try to explain for you. Two 24v packs wired in parallel is 24v total. Four or eight 24v packs when wired in parallel is still 24v. One hundred 24v packs wired in parallel is.. 24v.

Adding a second pack increases your total weight, so while you do have exactly twice the watt hours to burn, you will get slightly less than double the original range switching between those 2 packs.. Because you are hauling a slightly heavier load. However, wire the two packs up in parallel and the peukurt effect is reduced significantly- Presto, more than double the original range is the likely outcome.

Go google series and parallel wiring. Peukurt too while you're at it. There's really nothing wrong with being ignorant of this stuff.. that is unless you're going to go spouting off at somebody with the wrong info. Go search for "my1018" and "ananda" on ES also. Maybe that will help you find your oh so elusive info on bumping up voltage on ezips.
