I'd like to upgrade the 250W controller on a low cost e-bike that I just built. My battery/BMS can handle 30A and I think the brushless geared hub motor should be good for around 25A as well (at 36V).
I came across the YUYANGKING YKZ4830MM controller on AliBabba and I think it would be about perfect. This company offers a whole range of controllers with various amperage as well. I would be willing to get one of their high amperage controllers as well (within reason - don't need their monster controller) as long as I could program it down to for this bike.
The only place I could find one of these for sale was on Luna Cycle, but they were listed as 'out of stock'. Also, they didn't actually state which model was being sold, only '60 amp' which narrowed down the possibilities.
Anyway, anyone have a suggestion on where these can be bought (one at a time)?
Also, if anyone has a low cost 36V controller that runs around 20A - I'm interested!
