Electric Bikes - Battery Trailer?
Bikeforums.net is a forum about nothing but bikes.

I'm all set to order my first E-bike conversion kit and I have been thinking about range. Let me tell you what I would like to do, what I think will keep me from doing it, and then I would appreciate your input.
I would like to carry three optima yellow top batteries in a cargo/child trailer. These have between 48 and 55 AH depending upon the model.
I think it won't work because I thought I read somewhere that the controller needs to support AH as well.
If I am incorrect about the controller being the limiting factor please let me know. Otherwise (aside from the extra weight) why would this be a bad idea?
[EDIT: The kit I am considering is a 36v 600w on Ebay]
Cheers

instead of going through the hassle of building an electric car.I am interested in making my ebike replace my vehicle
My original thought were the same as your. I have a child trailer, and I thought I could put some 150 Ahr RV batteries on the trailer and that would be enough power to run around all day long without needing to stop for a recharhe.
I still like the idea.
But, while reading on this forum, someone's words rang true for me, and I realized that I also wanted to run the ebike as just an ebike,
So I am. Just running the ebike for what its worth is going to be fun and it gets me using it right away.
Meanwhile, I'm going to scheme and brainstorm a little on how to build a trailer with lots of battery power, and I'll even add a motor to the trailer to offset the added weight.
I think it won't work because I thought I read somewhere that the controller needs to support AH as well.
no, controllers don't need to support amp hours, just amps.
(that is, if your controller is "asking" for 30 amps your battery should be able to supply 30 amps.)

I only use a trailer for grocery shopping. I can tell you that the weight is better distributed back there and can take the bumps pretty good back there. Although I can't ride it down a shoulderless road because it takes up half the road. I need to ride it off to the side when cars come. Good thing I only have a half mile strip like this. The trailer also slows me down 2-3 mph empty and about 3-4 mph full of groceries. That's why I only hook it up when needed.
You certainly can carry a lot of weight with it though. I'm considering lining the bottom with a 3/8" plywood, then it can probably take 300 pounds of cargo.

Alway bear in mind the importance of a proper flux capacitor.
So, pop some smoke and get out there.

I haven't found a good source of plutonium so I'm going to do my best to get around running one. We do not get that much lightning around here either, so that's not really an option. :D
