Thanks for the kit! Awesome. I originally did the 16 tooth motor mod on my base ezip, which got me to 20mph. However,I can average that on my regular road bike. This controller upgrade got me that extra 5-7 mph top-end speed that really makes commuting by ebike worthwhile. Thanks again.
With the 48V system (two 24 packs in series), you get twice the capacity. Going full 25mph you probably get about 15 miles with a new pack, or slightly less, depends on how much you pedal and how fast you set the maximum speed.
There are also LiFePo packs available from Currie now! They fit directly into the RMB racks. That's the simplest way to making a 48V light-weight system with high speed. But those cost more than the lead acid packs of course.
Nice work, I have the same bike. I have been thinking a lot about modding my ezip. I had planned on 36 volts, but... and, I was also really wanting to upgrade the battery technology to ni-mh or li-ion if money wasn't an obstacle :) I still would like more runtime / lighterweight than the lead acid can offer, but I might be sold on your 48 volt method because it allows the adjustment of top speed.
Can i ask how many miles you are getting from your two pack fully charged?
Perfect timing lol I'm working on my third ezip izip its is brand new. My last was 36v wanted to do 48 but wanted it clean this may be whats next for me. I will have to email you. I have a few tricks for the ezip as well! Awesome
