Ecooter e2 Max

[Eskildv]

I’m looking for a new controller with more power for my Ecooter e2 Max.
I’ve talked with a Ecooter dealer who has pre programmed controller and he claims its an encoder type controller with 150a but won’t tell me the phase amps. Problem is it is not with regenerative braking and I it’s not programmable if you don’t have the equipment which i can’t buy. So I’ve been looking at the fardriver nd7360b and the nd72450b. However I don’t know how many phase amps I should program it. Is there relation between the line current and the phase amps? Ideally I would like as many phase amps as the nd72450b can provide but I’m guessing that would burn the motor and maybe not match the line current of 150amps. So do I just monitor the motor temperature, start low and try little by little to increase the amps?
Btw the stock controller I have now is 64v 65a

What are your battery's specifications? You must use a controller that doesn't ask for any more current than it can provide, either peak or continuous.

If the existing battery is only able to feed the existing controller's demands, you will need a new battery to replace it that can feed the new controller's higher demands, whatever those will be.


Can your present battery accept charge current vai the discharge port? If not, you won't be able to feed it the regen current from the controller, and would also need to replace the battery with one that can.

Also, at a higher current your battery will give you proportionally less range, so if you need the higher performance *and* the same range you get now, you'll also need to replace the battery with one that has enough capacity for the higher range.


Before you start buying any parts, you should also find out how much power you need to do whatever job it is you want the scooter to do for you, under the specific riding conditions you have. If you note down all those conditions, the speed you want to go, the acceleration rate you want to have, the terrain, road conditions, winds, total rider/scooter/cargo/etc weight, and take that to online calculators or simulators like those at ebikes.ca you can use that information to guesstimate the power you need, and the battery capacity you'll require for the range you want.

I will make a new battery. 20S20P with 200a continuous discharge, and 68a peak charging current (based on fabricators datasheet).
However the budget isnt for that kind of battery yet, instead i have 5 pcs motorcycle lead acid battery i will connect in series to make 60v battery, with 190a discharge current to begin with.
Im in it for the learning process, and it would be fun to have some more power when driving around. In the future i would also like it to have a range around 60km at 80km/t.

Ive talked with the seller of the fardriver controllers, and they need to know which type of encoder the motor uses. I cant find any information about this though. Ive seen a guy on youtube converting his motor to hall sensor, so maybe thats the trick.
