Re: E-S Stealth Electric Bike Owners

They told me at JW Batteries that they're not currently shipping internationally because they found out it costs about $10,000 to certify a battery pack for international shipping, and the cert is only good for that one size pack. Every other size pack would need to also be certified for additional...

Re: E-S Stealth Electric Bike Owners

If we lived in the same country, I would have you build me a 20s 5P out of these cells. Both my P7Rs are about the same width as my Bomber frame, and there would be enough room for single layer in that frame. With the right motor and controller, it would be a runner with 1.8kwh without the funky vo...

Re: E-S LMX 64 Bike Owners

I know its like comparing apples to watermelons, but I had to run 3 auto detect cycles on my Adapto to get a combo of settings that allowed the motor to perform really well with out heating things up. I would say the next best customisable, feature rich controller after Adaptto is the Nucular, so n...

Re: E-S LMX 64 Bike Owners

Thanks again for the suggestions on re-trying auto-detect on the motor. I tried a few more times and eventually it managed to get it right.

Bit of a worry it takes so many tries, but at least it's working again now. :)

Re: E-S Stealth Electric Bike Owners

I'm guessing reason they don't use those Samsung cells is probably because of the low discharge rate. 9.8 amp vs 45 amp. If they don't want to build the pack to the maximum possible capacity/size, then yes this makes sense. However all it would take is a 10P pack and you've got 100A of discharge......

Re: E-S LMX 64 Bike Owners

Thanks for all the replies!
Yes the 15T works great and I think it's the best balance between speed/torque.

I will try redoing the auto setup as suggested. I really hope it's not a dead hall. I've replaced them in hub motors before, is it as much of a PITA for these motors or even possible?

...They have higher c, higher capacity cells that they could build a Bomber pack... I call BS. If they are talking about 18650 cells, there are no higher capacity and higher c cells than the Sanyo/Samsung/LG 3500mah cells. These are still the top of the pick after 5+ years.

Unfortunately not possible for streel legal ones due to the homologation, only 14-118T is possible. However we are also testing polychain GT carbon for hopefully longer life.

Hi CD Ran the first time this year full throttle with the 15tooth sprocket. I’m back to 56kmh. I don’t notice any change in torque. Feels like the chain 14 to 100. But the LP belt is close to soundless. At 225km now. That’s a 4 to 6kmh improvement. Love it. PS the new suspension set up is far super...

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

I think the replacement nut stripped my threading on the cassette side of the axle. The odd thing is that it did not show any indication of cross threading when I installed it with a small crescent wrench and took very little force to turn. I was mostly able to turn it by hand. The nut was still ti...

Re: E-S Stealth Electric Bike Owners

Why would it be cooked? Any current Lithium chemistry doesn't like being discharged that low, and it can start to cause cell imbalance. Lifep04 is a bit more forgiving, which is why I say see how you go...to be fair, I would be doing exactly the same thing, but it's just worth mentioning and to be ...

I worked it out... Yeah, but you may have cooked the battery. See how you go, but capacity might be lower now. I'll never forget trying to keep my stock batteries going as long as possible by reducing the amp output on the CA as they slowly killed themselves. Did that with 3 batteries before I gave...

+1 for the Hope/Magura combo. I ran an MT4/2 front/rear on my Fighter and now run an MT5/4 front/rear on my LMX 64. Works a treat as long as you bleed them well.

Re: jonescg's cylindrical cell build thread

That's a big battery! But that spot welder sounds a bit slow :shock:
I can weld faster with my JP welder. When it gets hot I just wire up a little 12V fan running over the mosfets that way I only need to stop when the probes get too hot to hold. 8)
