I just joined this forum since I learned a lot from this forum. I’m reaching out to you guys hoping that you’ll give me some info and suggestion. I recently bought a used e300 for a good price ($40) based on the area I’m living (nyc.. everyone here are into urban transport). Everything works well but I’m not satisfied with the speed and shorter battery run. I’m 180 pounds and here’s what I tried to achieved in order
1. Long run
I understand that there’s a lot of option there, but the more I search the more I lean towards this option, again feel free to correct me if you have any idea that will fit me better. I want to do “overvolting” to ensure I have a longer run, so basically running 36v on 24v motor and 24v controller or the other option is running 48v on 36v motor and controller. But I think running 48v is little hard for me since I’m want to avoid fabricating as much as possible (I know it needed for bigger motor and 4 batteries). I live in small apartment in nyc and only have a simple tool like small dremmel, drill, and handsaw.
There was a post by Rob mentioning to use 2 stock motors in series, one on top of the stock one. This looks promising for me since i don't have to mount a new bracket for bigger motor, I can keep the kick stand, etc.. I think this will improve my torque drastically beside changing the sprocket to 80t. how many Ah of 3 12v batteries that the best one to do this job? The controller with adjustable throttle that was suggested before also out of stock now . Any suggestion or advice how to make this happen ? or maybe even other system set up that efficient? I want to keep it using a sla for the cost and safety.
Thank you in advance ..
