The higher voltage is not a problem.

But I would not trust that cheap a CB for anything critical, the car stereo world is 99% crap.

Fuses are really the way to go at high currents.
True. I'd like to build a nice little N channel mosfet switch. I was thinking 3 IRLB3034s in series.

Will this 100A circuit breaker work at 48 to 72V?

Ive seen these run at 24V and 80A with no issues on an electric winch, but how would higher voltages affect them? Pretty skookum looking, and rated for 100A. https://www.ebay.com/itm/CAR-STEREO-AUDIO-12V-CIRCUIT-BREAKER-FUSE-INLINE-FITS-4-8-GAUGE-WIRE-100-AMP-US/222368466606?hash=item33c63186ae:g:UQ...

New (and different) Luna 60A Cyclone controller wiring

Last year I ordered a Luna 60A Cyclone controller for my bike. I'd built them before, and I also own a 4000W with yet another wiring configuration (waterproof plug for both phase and hall wires). Anyway, I wanted to clean up the mess of loose wires and plugs that come with this controller, so I remo...

Hi you asking for alot poted vs unpoted. Motors I am no pro i would take unpoted motor . I can mod it Best of luck Potted motors can run much cooler.

Does anyone have one of these AND a mini cyclone? They're essentially the same size and technology. It would be nice to compare motors, gears, noise, performance, etc.

Re: new cyclone 3000 w mid-drive kit?

How is the noise without the planetary? Could you pedal at low power if you wanted? No, you would cook the motor putting any meaningful power down, say going above 30kph and sharing the work with the motor. You can pedal, but the motor would be resting. :lol: How would you cook the motor? That c4k ...

Ultralight and narrow Cyclone 4000W :-)
11/72 gearing, so gearbox is needless.
About 2kgs less weight compared to my previous setup.

Re: 36V BMS on 72V battery for charging?

None of that makes any sense to me, the last sentence especially needs rephrasing. But no, the BMS should fully protect its pack. Create two 36V packs and then run them in series to get 72V. Well, I answered my own question through experimentation. By "accumulate voltage" I mean B1 is 4.2V, B2 is 8...

36V BMS on 72V battery for charging?

Is it possible to put the sense wires on every other cell group to double the number of cells it will balance? I know resolution would be cut in half, but do they balance at 4.2V (typical) do they actually accumulate voltage all the way up to 36V in the case of a 36V BMS?

$25 wattmeter would indeed tell us a lot.

Without a measured result ( and OP did not bench test his cells before ), we are lost in the woods as to the real power output.
