Two 24 volt battery packs wired in parrall to give 24 volts.

I just modified my Ezip. Two 24 volt batteries wired together. Still 24 volts, but bike seems to respond better.
No speed increase.
ANY THOUGHTS..

You increased your stock 10ah capasity (1 pack) to 20ah (2 packs) so of course you reduced the voltage sag which deliveries more torque. IT should actually deliver better speed when compared to a single pack after it starts to run down. With 2 packs you should still have power left the you otherwise wouldn't. The best improvement is in the battery life increase because you are sharing the load between the 2 packs. I have been recommending people do this on other forums for a long time. Why Currie doesn't have the bike wired this way from the factory is beyond me.

Now if you really see an improvement try 2 24v 20ah lifepo4 packs.

I may be getting a little more speed. Will have to have someone check my top speed or purchase one of those speed-o-meters.

I couldn't agree more. Less voltage sag is good even if you have to get it the hard way.

At one point I added some nicads to my lead on a 24v EVG. My top speed did increase by about 1.5 mph, from 11.5 to 13 mph. The real benefit was a huge range increase, since the batteries were sagging less in paralell.

Same here. When I had a 10 Ah lithium and a 15 Ah lithium in parallel I got a little more speed but definitely more speed off the line due to less voltage sag. When I run just the 15 Ah I see close to a 6 volt sag whereas in paralell it was virtually half that. Which makes sense, overall C rating is increased by splitting the load between two batteries. Plus it makes both of them last longer. Goin' ridin' right now in fact 8) ...
