What controller to use on Jansno X50 750 watt with upgraded 52v 40 amp battery?

[E-bikewolf]

I have a 52v 24ah 40 amp battery that I want to put on my Jansno X50 . I would like to know if anyone can tell me of a good controller with a display. I'd really like an S866 display but I'm flexible on that.

A 48V controller will run on 52V. Just put on the battery and ride. Whats the current rating on the Jasno X50 controller now? I am guessing 20-22 amps? Maybe leave it alone, If you are going to change, buy a Jansno model form their web page.

The motor you have will take 52V, but it looks too small to me for 30A. .

The controller on my X50 is 25 amp the display setting goes up to 22 amps.

My 52v battery is 40 amps . Thank you for the help.

You'll spin the motor a little faster with 52V, but you already have a 25A controller then, I saw some youtube reviews. That bike goes pretty fast with a small hubmotor. I don't see much gain.

I live in a very hilly city. In fact it's called Haverhill. So I need a little more power. I want more range as well.
