Need Dolphin Battery repaired

Hi all, I had my 52V Dolphin jerry-rigged on my too-short top bar and my son accidentally tried to connect it to the motor reversed. Big spark, blown BMS. Luna says it is a discontinued bms and for me to install the new one will require rewiring the harness as well. This is beyond me. DOES ANYONE IN...

Re: Ebikes practicality for cross country expeditions

To make solar single-track viable, you would need to have a setup where you do almost all the work (low power consumption). High powered cycles advertises a fold up solar panel that makes it look like you can just unfold, eat lunch, then ride away with fully charged batteries. Don't be fooled by th...

How do I wire it?

Now I have a 36V electric bike without the battery. A 36V solar panel on a trailer and two 1.5ah 18V lithium drill batteries. What I want to do: Have the batteries buffer the panel's output so that the panel is continually charging the batteries and the batteries are driving the motor. How do I wire...

Can you run a motor without a controller?

I am trying to cob together a simple solar bike demonstration. I have a solar panel (Vmpp 32V, Voc 38.9, Pmax 285W, Impp 8.88A) which I put on a little trailer. I have a cheap ebike with a 36V rear hub motor, no name controller and no battery. When I connect the solar panel to the controller, replac...

What voltage(s) will the motor run at. Have you used it and what has the performance been like? I live in New York State. Where are you?

Hub motor on front suspension fork?

Luna says not to put a hub motor on a front suspension fork? Why? What goes wrong? Is it inherently dangerous or only if you hot rod it?

Can I charge my Luna 52V Dolphin pack with a 285W solar panel by using this MPPT Solar Charge Controller set at, say, 56V or 52V? Will it damage the battery?

Thanks, I'm pretty wet behind the ears.

I want a 1000-1500w hub motor with regeneration capacities that will work with voltages from roughly 28 to 60. This is because I would like it to work (for educational purposes) directly off of a 37v solar panel I have and I would also like it to work with the 52V batteries I already have. I do not ...

Thank you, oh canine responders! Dogs and Wolves know how to build the pack! I read through all the "theebikemotor" links and I appreciate the tip that the new display will allow pas and some programming control. I'll see what the shipping is and then take the plunge.

Re: Kepler Friction drive comes of age.

John had a similar thought to mine. If you don't want to go into sales (except the swing arm mechanism), then a webpage that gets updated with successful combinations of batteries, controllers, engagement hardware and motors and their sources. Very impressive work!
