Wrong app

[Kirill]

Hi everyone!

I can't turn on the discharge at Xiaoxiang BMS app.
Every time switcher goes back.
App purchased.
BMS bought on aliexpress.
The seller sent only instructions.

I wouldn’t think that you could charge and discharge at the same time. Have you tried to turn charge off, then toggle the discharge?

Of course. I checked the possibility of charging before.
Charger not connected at all now.
On demo pictures both switches is ON.

You may need to turn off the "switch function" in the app.
Don't have the iOS version, you'll have to check your settings.

Could it be that you need to apply a load to see the discharge info? I notice that your picture, you have 0w power, but the demo, there is 400w power.

Nope. This is a switch. Charging is not going on. But the charging switch is on. Means not matter.

Of course I checked. No “switch function”.

Twice was write “port success” and twice “port failed”

I'm 99% sure you need the first toggle switched off under the function setting tab. If the iOS app doesn't have it you'll need to borrow an Android Phone.

Are all the values the BMS reads from the cells and sensors within the limits the BMS has been set to? If any of them are out of range, the BMS may be setup to prevent discharge to protect the cells.

If the cells are actually all ok, as are all the sensor readings, but it's just the limits that are wrong, you can change the limits so the cell values or readings will then be within the limits.

The most common problem that causes this is a difference in voltage between cells, usually greater than 0.1v. (depends on the BMS's settings or design), but your screenshots indicate this isn't the case here.

All works. I'm wrong did read/save.
Thank you all very much!
