I have a 36V10Ah lithium-ion battery (that includes a BMS) that I need to recharge. Unfortunately, the charger for it is not working well. I also have a 36V NiMH charger and a 36V lead-acid charger lying around. Could either one of those be used to safely charge up my li-ion battery, if the...

Well, so far I haven't made long runs as it's pouring outside and looks like it will be for the next week, but shorting out the motor (works without even using the batteries!) slows it down well, with 2 phases creating that rumbling (I'm used to it on electric skateboards which are a lot noisier...

What does it do to the motor? Any chances of damaging it?

Hubmotor: Golden Motor 500W 36V I have done this setup with a proper coil (varnish not vinyl), two wires from the motor, and it gave a bit of braking power. Yes it is giving that good old rumbling. Yes it gives proportional-to-the-speed braking power. I shortened the coil by a good 4 feet...

I don't have a switch, I just got a plug. Why would I put a switch on a battery?? And where: on the + wire??

Ahem. OK.... so.... how do you do that? Diagram for dummies please! :mrgreen: There's already a fuse on the + Positive wire going for the discharge portion (hub motor).

OK, thanks everyone for the answer. Now, another question: can I just leave the power plugged on the motor when I charge the battery? You know, since they both use the + Positive wire... If I could, it would save me from hearing that POP every time I want to charge! (just erring on the safe...

I have bought a PingPing LiFePO4 36V15Ah battery, wired everything properly (not very tough... positive to positive, and negatives to their proper charging-discharging route), and I was wondering if it was normal to have a spark when things get plugged. When I plug to the hub-motor, there's...

OK, so you were right. Just as I tried fitting my hub motor in the rear dropouts, I had to spread them apart for things to fit. The aluminium bent..... I'm not taking any more chances, I'll go for a full suspension steel frame! Found 2 on eBay with 26" wheels: PACIFIC Highlander (100$...

Well, so far, I had to spread apart my rear dropouts to fit the hub-motor, and even with a high quality aluminium frame (Giant AC full suspension) I noticed later tonight that... it bent. My beautiful MTB has bent alu. Not good. Looks like I'll forget about using it as my donor bike, and I'll...

John, what do you think if I just measured properly, identified where the holes should go on the cover of the hub, and just drilled small holes (without taking the hub cover off) and screwed in the disk rotor, with a good measure of glue that bonds aluminium between the hub cover and the spacer...

What happens with the included Golden Motor cantilever brakes that halt the engine, when you only have disk brakes on your bike? I thought you needed to use those to take away power to the hub-motor when you are braking??

Actually, that sounds like a great plan! Do you think the welding would be strong enough? And, would the heat from the welding damage anything in there??

Couldn't you just screw the disk brake directly into the cover, without taking it off nor opening the hub? What speed are you getting with this setup on flat no wind?

If the engine spins at a maximum speed, a larger wheel will cover more ground in a single revolution, hence the 15% or so better speed. I must say, though, that looking at electrified FS MTBs, and then clicking on the link I gave for that Giant road bike, which looks so plain, the FS MTBs look...
