Hi,

I want to upgrade Super Soco TC but step by step. I don't want to purchase kit and change everything.

So is it OK to start with new controller KLS7230N (KLS7250N)? 

I know that with factory BMS it will not have enough amps but I will figurate something to override BMS. Maybe even new battery with more capacity.

Will I get more speed and acceleration with this?

Idea is to install better controller to have little better performance now and to have options to replace motor in future for much better performances.

Just buy a niu battery, these one are pretty cheap second hand and have the same voltage levels as the stock super soco batteries, or get a bigger super soco battery, see my topic about it.

The niu battery has almost the same size as the stock, only a little bit shorter, only needs opening to remove the lifting handle and thats it, buy a XT60 connector with cable and remove the stock connector and youre set to go.

Hi,
I wanted to build a custom battery to upgrade my TC so that I can drive a bit faster and for better peak performance but since I have very little knowledge about the electronics I'm thinking to buy a finished battery. I would like to hear your opinion, what do you think is it better to buy a Nui battery just like you suggested or should I go with this instead. Thank you in advance.

But I think that bigger battery is not enough without new controller?
I think that factory controller is not capable to provide more amps to hub motor.

Or am I wrong?

Hi,

I want to buy another controller, but I'm not sure which one other than that I have no idea how to connect it. You can be right but I don't have the technical knowledge to say if you are correct or wrong, sorry.

The niu battery are availible rather cheap, i paid 250 euro for two of them they are easy to open, so if you want you can change the BMS for higher peak current, or you just make a cable with a xt60 connector on, and connect it to another safety breaker and then on the controller, this way you have 26ah and 29ah battery in parallel.

For better performance you have to change the controller with another one, this involves making some wiring connections and checking the soco wiring diagrams.

I will make some foto's when i get my sabvoton controller, i will make fotos of the wiring connections, so you can duplicate if you want, its not that difficult.

If you do it this way you keep the battery consumption information on the display.

Hi,

Thank you for your answer. Where did you buy them if I may ask? (250€ --> assume you are somewhere in Europe like me)

As I'm a noob, I would love to see some photos (or even a short video would be perfect) duplicate your work. I'm looking forward to seeing/reading any suggestions. Thanks in advance.

Under normal circumstances, it is necessary to replace the control and battery (BMS). The current limit value of the controller should be consistent with the current limit value of the battery. The current limit value of the controller can only be less than or equal to that of the battery.

I have replaced the controller with a kelly and put the niu battery in parallel. Did a small test drive this evening and the power is amazing compaired to stock setup.

Great job and thanks for sharing!
So you just add one battery in parallel with stock battery and replaced controller?
How did you connect new battery? Directly to controller?

Can you share some drive test video?
Thanks
