Wondering if anyone (other than EBMX) has done an Ultra Bee controller swap yet. I'm due to get another Nucular 24F and will have to come up with the wiring harness connectors.

Downside to the Storm Bee is a used Alta is better, lighter, and cheaper.

Gotcha. You're just looking for a LB 2.0 :) I suspect the Ultra Bee motor will take a much higher peak. I'm running 18kW+ peak on my LightBee and I know it's days are numbered. If truly thrashing it, the LB motor goes into temp shutdown too. The peak isn't so much the problem its the...

How? The extra capacity alone would be 20#+ adder to a light bee. Doubling the motors power isn't a free lunch either. I have one on order already. Anxiouslly awaiting the chinese new year celebrations to wrap up for things to get rolling again. I *LOVE* that it has a bigger frame, better...

Handy 3-n-1 machine and very nice optical(?) table. The spark is the inverter's bulk filter capacitors charging up. You need to precharge them or use something like an anti-spark connector (AS90) to do so. Fuse your battery connection as close to the battery as practical. That MPPT has to...

I've seen some folks take their motors apart to upgrade wires or spray the laminations to stop rust on youtube. But anyone ever 'pot' the windings? Should be able to add a thermal potting compound to help the windings get heat out to the housing. Likely make the thermistor read faster and...

Got it! Where did you find a 60-70V MPPT and inverter? 12/24/48V are pretty common but not higher LiPo voltages. Edit: The SurRon BMS open circuits when it reaches full. You're going to have to be really careful if running an inverter from it also.

MPPT charges your storage battery. In my case thats a 24V pack. (I could also theoretically charge this from the vans alternator when its running using a converter.) For the sake of discussion here, once the energy is in the storage battery it doesn't really matter how it gets there. Inverter...

Understood (for your "computer and Starlink"). Just saying there may be a more efficient charge method if you ever need to go that route. I'm in the business and bought one of the higher eff inverters (Cotek.) I only have ~500W of solar on the van and ~5kWh of storage. Trying to run...

Anyone know what the X160 battery pack BMS current limit is? Put a Nuc24F on the kiddo's bike and am figuring it out experimentally :) Was tripping on me going up a big hill riding at a friend's house. I don't have a hill that big around here to tweak it further. 3DTOPO: FWIW, the Nucular...

Has anyone setup a Segway X160 before? (= a SurRon w/ slightly narrower motor rotor/stator and 48V battery.) I already have a Nuc24F on my SurRon and LOVE it! So ordered another over a year ago to put on the kid's X160. I got it around the start of the year and finally got around to...

I would think a steel (ferrous) ring wound be better. Blocks stray flux from the rear and the rear flux linkage will make the face field stronger/more defined.

No. Axle to ground dimension is controlled by the radius of your wheel. These links change the geometry of the shock/swingarm/frame so that the static position of the frame is lifted relative to what it was before. They can also change linkage travel/force ratios.

I treid contacting Litespeed multiple times. Calls and email. They went radio silent. :( Anyway, think I finally found it. AliExpress had 335mm (flat dimension) polyolefin. From my measurements (battery is 140x160mm), I need about 300mm so that must be the stuff. All I could find before...

It works fine and fits. Just looking to repair the packs.
