I was only saying to connect the 2 packs together because this does extend the life of the packs and the distance you can travel. Of course I was speaking parallel wiring the packs together. This would give you a 24v 24ah pack. The value is less voltage sag and allows you to run then a little deeper then you normally would. Consider this; lets say you take a long ride in your current setup. You ride until you notice a lose in power and switch to the fresh pack. We all know the low pack shoud go on charge ASAP after use but your still riding so it can be chaged. You need to wait until your ride is over and you return home. But when both packs are wired together in parallel this is not as great a problem and the packs live longer. I have some old SLA 24v 20ah packs that are 4 years old and still going strong. But I prefer my Thunder Sky packs hands down.

You would have to do a lot of configuring to mount a 24v 20ah pack in the "V" area of that bike. You could of course mount it on the back over or next to the rear tire like EZip does. My old bike has the packs mounted to the sides of the top bar and my Ezip has them mounted on the rear tire. Given a chose I totally prefer them mounted to the top bar. The biggest problem I have with riding my EZip is all the weight on the rear wheel makes the bike unstable in my opinion.
