Which controller for 60V+?

[crazymaster]

Hello!
Currently i own 1500W rear hub motor with LCD3 and KT controller 17ah current and 35A max... which blown today with unexpected reason(previous day was working perfect)

This is my kit: https://pedalease.co.uk/index.php?rt=product/product&path=67_73&product_id=13172421#review
Its on ebike.

Right now i want to boost the bike(and maybe even make stealt bomber bike in future with the parts).

Please suggest me what controller(if support LCD3 Or other nice screen will be big advantage) i can use on this motor? Is it ok to run it at 60V or even 72V?
Please suggest me exact links of what u think that can work for me. I am delivery driver so i make 100km+ daily.

For my needs i calculated that i will need 48V 50A(2400w) battery to work full day, but when increasing the power/voltage maybe i should get battery more than 2400W to reach same mileage or no?

Any controller to support lcd3 has to be made by Kunteng so needs to be KT prefix.

The 72v LCD3, the other one is for 24,36 and 48v

And the controller shoulw be for 2000-2500w, because my motor is 1500w at 48w

That controller will give you around 2800w at 72v, but you can reduce the amperage with the LCD3 if you wish. To build a 50Ah battery pack you will need to look at the latest 5Ah 20700/21700 cells, otherwise you will need a trailer for the battery. 48v 50Ah=130 cells, 72v 50Ah=200 cells.

The easy way is to parallel a couple of these then parallel another couple then connect the paralleled packs in series.

That would give you a 36 Ah 72v battery weighing 13 kg and costing 1280€. It will be good for 35 A continous discharge.

Edited because I used my link to the 48v pack

The 72v LCD3, the other one is for 24,36 and 48v

Yes quite right AK, good thing about the fora two or three heads are better then one.

The main problem here is the controller and LCD, battery combinations are easier to choose
I cant find big enough controller with nice LCD3 or another nice screen?
