Towing a battery

[djward43]

I bought a 48 volt battery that came from a solar system. I'mtm towing it in my Radio Flyer on 12 inch wheels. I'm planning on switching 48 volt hub motors from eBikeKit to Golden Motor.

That should give you pretty good range.

The briefcase is like trailer mudflaps or what?

I need to do something similar. Nothing much is close around here 25 miles one way to any town large enough to have more than the most basic of grocery stores etc..

That's cool, I had that idea as a have a couple little kid/cargo type trailers, realistically a lot of battery weight could be towed. This is a future solution for extended travel with multiple separate batteries.

It's a 30 amp battery so I almost tripled my range.

Actually I had the briefcase to protect the laptop I had just purchased on Marketplace.

If you look close, you'll see I'm towing from the center of my bike (which just got stolen) instead of from the side.

Amp, or amp-hour? It's a very important difference:

Amps are current it can provide when demanded by the controller.

Amp-hours are capacity to provide those amps over time.

Trippled it

A trailer is a real PIA in so many ways. Unavoidable when carrying cargo I suppose. I carry 35 ah on bike in separate batteries (14s5p on the down tube and 14s6p in the trunk bag) together in parallel and still have room in the saddle bags. Really doesn't feel that heavy either.

That's a lot of battery, and on an OG rigid frame and fork, with a narrow front wheel. I get spooked on those narrow rims over 25mph, looks like a fun DIY

The conversion has 11,000+ miles and has held up very well. I'm especially amazed at how well the spindly (steel!) rack has held up. Besides the 14s6p 18650 pack it has at the bottom of the trunk bag it carries my tire change spares and stuff, gloves, hat, lights, tools, etc. Then it has the saddle bags that I always stuff with clothes or shopping stuff. I'm comfortable up to about 35 mph and have hit 45 mph a few times going down the right mountains. I'm in southern New Mexico right now and everything here is rock not gravel. Been beating the crap out of it the last few weeks. I'm a country cruiser and enjoy a 40-50 ride on paved roads. but, I do need to get something more capable off-road.

It really can be a PIA when it comes to getting the weight low enough to the ground. One thing is I am not pulling from the hub area. The hitch I have is a scaled down "normal" vehicle setup with an actual ball I mounted to my rack. I wouldn't consider an inexpensive kid hauler as a substitute. Truly, if you like the feel of your bike empty, you'll love a trailer.

I'm actually going to go check the amp hours on my battery... STAND BY:
