WXBULL controller wiring help***

[akookie]

Hey I was wondering if anyone could help me. I've got a WXbull 2000w controller and the voltage says 48/ 60v /64 / 72v / 84v . Now is that controller ready to run 84volts.. or do I have to solder something on the PCB board. Because there is a spot on the board that has 60v / 64v / 72v / 80v. Can anyone help me.. I only noticed the numbers written on the pcb board as I was soldering up the shunt..

Cheers

That is for low voltage cutoff and such. Install jumper connecting your size battery.If you dont put a solder slug across it should act as if it is run by 48v. I have a 3kw controller by wx bull that has the same thing but it's common for most cheap Chinese controllers.

are you saying you have to solder the two in the 80v rectangle together for it to use 80 volts?

Keep in mind that it may have spots to connect for different voltages, but that doesn't mean it has the parts on it to support all of those. For instance, it might only have capacitors, fets, and various parts on the LVPS that make sthe 5v/12v/etc from battery input, that can only handle up to 50v, or 63v, or whatever.

It may also have software programming that has to be changed to go along with those jumpers. Or it could be programmed to ignore all of the jumpers and only use the factory settings.

do you have any idea if there is software or not? ive looked everywhere and emailed the company from their webpage because i just bought one of these too on aliexpress and they told me they would give me the software but then said they cant get it lmfao im going to try to message the company i THINK might be them or related to them on alibaba and see if they can help me but i really dont know at this point i got some info saying there might be some software i can use like xpd to get into it and it might be read and writeable but at least i only spent like 35$ on it

so the manufacturer messaged me back and basically said no there isnt any programming software for it and nothing can be changed "I'm sorry, the controller produced by our company is just a regular brushless motor driver and does not come with any programming software, so you cannot program it. However, there should be a product manual inside the independent packaging box of the controller. If there is no manual, it means that it was accidentally left out of the packaging box after being inspected by the dealer or customs personnel." which kinda sucks but i almost think thats bs you think youd be able to connect to it somehow and at least read information off of it, i have some programs i am going to try to use to mess around and see if i can read anything on it.

my controller is also a 3000w 45-60a controller, will i have to take it apart and solder something to make it accept more than 48 volts like was said? if i hook up 72 volts it will just only run on 48 basically so 48v 60a and 2880 watts? i realized today that these controllers are all literally the same like wuxi, green, jrahk, etc i havent taken anything apart yet so i dont know if they are different inside but they seem the exact same to me

It's self learning to 72 volts

As noted before, if it's only built for 48v, it may not have parts inside rated for higher voltage, so you may blow it up connecting it to a higher voltage pack.

Doesn't matter what the board inside has markings for--they can design the board to be used with many models, but they're only going to spend the money on more capable parts for controllers that require them. So...it might work, it might not.

Controllers don't have a way to filter out "excess" voltage--if you connect more than it's parts can handle, they fail. It can happen instantly, or over time, or under specific circumstances.

There's plenty of threads over the years about "overvolting" controllers, and about using XX volt controllers at YY volts, if you want to read about what to look for and what to change to make a lower voltage controller run on higher volts, and what the problems you'll encounter could be.
