Re: N.E.S.E. the no solder module

That is correct but it does not consider power requirements, therefore related to heat. So we said before we are forced to have higher capacity/storage to lower C output levels and reduce IR heat generation. If I want a smaller ~5-10kWh pack but capable of 5-10C peaks/short term output then cooling...

Re: N.E.S.E. the no solder module

Yes, preventing heat from being generated internally in the first place, if practical is far far better than needing cooling solutions. Lower C-rates and capacity utilisation can extend also lifespan by 3x 5x or more drastically lowering annual running costs Of course, but the weight and volume are...

Re: N.E.S.E. the no solder module

Well not water cooled, wondering what the limit of an uncooled pack might be, as Agnasium said, need a bigger battery with low current draw to mitigate high heat build up, in summary.

Re: The BEST and FIRST Qulbix Raptor mid-drive build!

No this is certainly not an issue of safety. What I did NOT want was a complicated system that could come apart and disable the rear brake or far worse jam the wheel. I trusted the Qulbix basic design and made it thicker and from better material. The pads are properly positioned when the chain is n...

Wow great progress Dui! Just wondering about the carbon parts, do you mix the fibre and epoxy before filling the mould? And maybe mix it thinner to better coat thee fibre?

Re: The BEST and FIRST Qulbix Raptor mid-drive build!

A solid mount is safe and won’t slip under use. I’m open to suggestions for an adjustable caliper mount. Pic 6 above, rear top view, the space between disc and swingarm where the caliper bracket mounts to the swingarm, that looks like a sleeve spacer on the axle. So I would simply make the caliper ...

Re: Ninja 250 "Clone" Made in China

Your build is looking excellent! I have a few thoughts if you don't mind? 1. How much does it weigh? Do you really need twin front calipers? It always upsets.me when a vehicle has too much braking. Remove 1 caliper and you'll have more power for the other caliper, lighter weight in the wheel for bet...

Out of interest have you weighed it yet?

Any plans to fit more battery in there?

Re: 1991 Suzuki Rm125 build

I'd say go with Aluminium, and weld it up yourself. TIG is so user friendly if you have a steady hand, just don't bury the tip in the weld pool and use good gas. Once you've practiced a few times you'll never want to not weld stuff up yourself. Regardless of the material also. And nice thing with TI...

Very nice J! Your packaging on your builds is well done, just a pity that controller couldn't fit under the seat. I hope it's out the way on the side there.
And the motor looks very promising, congrats.

Re: QS 3000w midmotor

You don't need any special tool to remove the pulley just have a rubber mallet and a triangular shaped shim to insert between the pulley and the motor flange. With a few small blows of the mallet the pulley will come out. If you damage the seal it is easily replaced. The reference is written on it,...

Re: New conversion project for Piaggio Zip 50

I'm not Votol expert. But the regen should be limited proportional to battery voltage yes. I don't know if the controller or BMS manage this. Regarding coasting, without regen the motor won't produce current because it has no circuit to flow through. The controller IGTs are 'open'. So it should be s...

Gianluca I am very sorry for you, that was a good looking machine. Must have been some fault in the controller if you did not change settings and the wiring was correct.

Wow that sounds very alarming, sorry to hear it.

That is very unusual. I would complain to the vendor. They should issue ...

I agree larsb. And bjork. The western offerings are like we wish but more costly. Curtis and Sevcon are good examples. Time will change things. Also modifying recycled OEM parts will develop like we already see, as availability increases.

Re: KTM 200 exc goes electric

I agree but it isn't an expectation that electric drive systems are offered like this to consumers so this isn't an adopted option for many. It would be great if we could simply adjust the controllers. It also boils down to liability and warranty and the OEM is not willing to honour their product wa...

Re: 1970 Vespa 50s electrification project

The build is looking good. Did you consider making polyurethane bushes for the swingarm for some vibration damping? Those seem ideal thickess for PU.
