Okay, so I've been reading other forums also. Being that I didn't sign up for any of them, I thought I'd ask here. Someone has a "24 volt" brushed hub motor like the ones we've been using. According to the thread, some have been using up to 48+ volt battery packs with the 24 volt hub. This particular person is running a 36 volt SLA pack with his 24 volt hub. So my question is, what do I need to do to be able to run a 36 volt battery pack with my 24 volt hub motor? Seems the hub motor runs fine with the higher voltage, but was wondering about the controller and throttle. Do I need to change these out for 36 volt units? Will it work with a 48 volt controller and throttle? These guys are getting up to 10 mph more speed by using bigger battery packs and I thought the option sounded pretty good. If it's workable, I'm going to switch motors and put the hub on my bike.
