Re: 72v 1500W 40A Hua Tong CA08 XM06AD_P04.1 controller

Sounds like that is the same version I have...
I can't open mine without rounding all the cheap screws out. An as I was only going to modify the shunt to take less amp's i can get to that from the plate of the controller

Re: Bafang BPM Dirty Greasy Rusty Motor

The motor still ran though. If it had better bearing seals It would have gone one without causing an issue. There's very little rust because of the grease! It even still worked when the bearing did collapse. It carried one running. At an extremly slower rate but it still did it. I'm sure the rain re...

Full-throttle, Thanks very much for your help on this matter! If there was a like or great help button I would have clicked it a damn few times.

Re: Bafang BPM Dirty Greasy Rusty Motor

I'm sure that if there was a better sealant or gaskets put on the motor you could avoid the water ingress. Keeping the same design you could use a gasket around the freewheel casing and silicone where the wires go into the motor. A better rubber o ring gasket seal on the other bearing on the opposit...

Re: Bafang at 96V: Would that work?

As long as the current isn't pushed over the rated capacity of the connectors you can use what you like!
I've always used powerpoles or andersons and you can configure them in what shape you like. But requires one for each cable. Rather than one connector for everything

Re: Bafang at 96V: Would that work?

Nope there not, but you can just shunt mod, or add nicks to the shunt to change the amp's.
The basic controllers are listed before only go up to 63v max.

Re: Bafang BPM Dirty Greasy Rusty Motor

Electrical wise its ran exactly the same as it always has. Never a glitch at all. The only reason I opened it up was becasue i noticed more play in the rear wheel. this was when the bearing was on the way out. The water has come through the axel on both sides as the seals are shot and with me runnin...

Managed to clean them up a little bit using so household goods. Will do the petrol outside and not in the apartment. My only issue currently is getting the old bearing that collapsed out.

Re: Bafang BPM Dirty Greasy Rusty Motor

Jump straight off it. Its harder to do on a 700c bike with a more relaxed geometry of a road bike but it can be done. Possibly whats caused it to crack. Also bunny hop up curbs. But i think its mostly down to the poor roads, weather and rain with speeds around an average of 20mph. The bike is a hard...

It still works yes... I cleaned it and used it this morning on my commute. It works but the sound is awful. I'm waiting for when I go over a bump and the last of the bearings collapse. Does anyone know the actual bearing numbers at all on the one thats split open. I think I've been riding in the rai...

Bafang BPM Dirty Greasy Rusty Motor

Hello all. Noticed of later the weather (UK), my commute and general aggressive riding style Is beating the crap out my bike. The poor thing needs a bit of an overhaul and some love. But in regards to this I've noticed a more metallic sound coming from my hub motor. Also noticed a small wobble comin...

Hello all, Mine turned up this morning a week after ordering. I've attached some pictures for refererence. I couldn't open it fully because the screws started to round off which is annoying. I'll have to cut them before I round them to far. So unfortunately I can't get you board pictures for now. An...

Yes but you will need spacers on the axel to bulk it out past the free wheel.

Re: Bafang at 96V: Would that work?

I wouldnt rely on the controller having the cut out higher for the LVC. Mainly becasue it would be better to use other forms of protections for the cells like low voltage alarms. It also would keep the controller quite flexible from 36v up to 63v (Which these controllers can handle just about). But ...

Re: Bafang at 96V: Would that work?

Are you buying a kit or you buying the motor only? The above would indicate that you are actually buying it in a wheel. Which only costs a few quid more anyway. If anything goes wrong you can always relace it. I know you enjoy a bit of work to keep you busy and relacing a wheel isn't that difficult ...

Re: Bafang at 96V: Would that work?

I agree with the above. The larger geared motor will be alot better than the DD hub. Espcially on this build. It will also be more effcient and allow free wheeling ability. The weight of the bpm is also 1kg more than the smaller motors and ok its a little larger but still quite stealthy on the rear....

Hello again cwah, You won't be able to go over 63v with the controller you have mentioned. 63v will be the maximum. Unless you get a 72v compatible controller from say lyen. So forget the above. Fact is you need with the above kit if you increase the volts you need to keep the amps sensible. Unless ...

Hello Cwah, As you have brought the motor @ 393 @ 36v you could use your current two Lipo bricks (10s1P) at 37v nominal to see how it rides first. I would also use the 9fet model controller. I don't think your aim is for it to be shit off a shovel quick and at 20amps the power will be fine. If you r...

Re: Bafang at 96V: Would that work?

It should survive in that size wheel so long as the amp's are low.
And the speed isn't to aggressive for it to pull to much heat. Just have to make sure you get a good controller to boot.

Re: bafang pmgr 24 v at 75v reliable?

So the answer is yes. But dont keep the throttle pinned down constantly. I only run the bpm at watts of 1000w peak and a top speed. The motor barely gets warm with my commute and that's with WOT 90% of the time. Hence why I'm going to try it at 72v for hopefully 30ish mph. But I think the heat it wi...

Re: bafang pmgr 24 v at 75v reliable?

My attitude is why even bother with the weight savings of a geared hubbie. Saving a few pounds only really matters if your tire is leaving the ground, and if it is then the shock loads on the gears upon landing is sure to cause a premature death. I don't think many people choose a geared hub for th...
