Any reviews on new72v Clyte ctrl?

[RatoN]

Did anyone use the 36-72V 48A Start Immediate Digital Controller (IRFB4110 Mosfets)
with 2x48v packs, for 96+v ?

I'm interested in buying one, but i would like to know your opinion first.

Unless they have changed the design significantly in the last 6mo. or so, I'd steer clear of those. The main capacitors are notoriously prone to failure, along with a few other parts.

If you buy from ebikes.ca, at least you will get good service and Justin will have you covered if something blows. He might be doing some extra QC on them as well.

Some people have had good luck with them. Some have not:

Personally, I'd get an Ecrazyman controller.

Thx for the input Fechter!

I remember that it was the mosfets that were the problem with previous models... now it's the caps!?

Though i'll admit that 96+v is pushing it... Cannot beleive after all this time that Clyte did not make a more robust ctrl. That co got some major problems.

Seems to me 96v is kelly territory.

Justin doesn't sell the above Clyte ctrl anymore... THAT kinda solves it.

Is that because the capacitors are worse on it than on other models, or that the people who buy it are more likely to use high voltage and thus expose inherent problems in all the controllers' capacitors?

 

[Drunkskunk]

I think it was mostly how easy they were to modify and push way over normal voltage.

The only cap problem I know of is the hot glue used to hold them down and a few breaking lose because of it. the last 2 I opened up had good quality, name brand caps rated at 100 volts.

Justin doesn't sell the above unit anymore because its the old version. the new version has been out a year or so.

I've got one of those controllers, maybe, and I'm only running 48V.
The 35 amp analogue controller was exchanged/upgraded with a 48 amp 72V controller off a back shelf at ebikes.ca. It had a label taped outside that read "Justin Canada" and 100 volt caps inside. It may be a prototype, hand built by Kenny after Justin's evaluation, of the new ones ebikes.ca has listed as Sold Out. Other, more experienced ebikers, have commented on how "smooth" it is.

The one I originally bought with the X5304:

The one I got as a warranty exchange after its failure at 687 km:

What mine looks like inside:
It's larger but lighter than its predecessor and has performed admirably for more than twice as long as the one it replaced. . . at 48 volts.

Do you see any difference in efficiency between the 2 controller (if you ride at same speed) I know one is 50Amp and one 35Amp...but keeping same speed watt/KM is the same?

No difference. At normal usage the 2.9 kilometer climb out from home usually drains off the first six tenths of an amp hour. Wh/km is about 17.5 at the top. By the time I've travelled another 5km to my destination I've used one whole amp hour and the Wh/km is back down below ten. After a few 2 mile round-trips to the store, that is along a mostly level route, my Wh/km usage was four point three.
I don't think the controller has hurt my efficiency. The CA has recorded higher spikes for max amps and the throttle seems to respond more quickly is all. I've gotten over 100 kilometers out of one charge with both controllers.
