Lithium Smart update error

Hi,

Yesterday during update of LFPSmart 25.6/200 VictronConnect signalized an error due to server connection issue. Unfortunately app crashed before i got to take a screen-shot.

Now battery bluetooth isn't visible at all and BMS is frozen in error state.

BMS is SmallBMS. App is up to date. App log in attachments.

We tried:

All solutions from the troubleshooting page.

Using different phones to connect.

Replacing BMS with another unit.

Charging battery with low current as if the battery was discharged.

Best possible solution for such case is usually restarting the device, but this time it's not possible as we are struggling with the battery itself...

I'll be grateful for any ideas.


Regards

Jakub

What was the firmware version of the battery prior to the update?

Battery is brand new, so that would be factory firmware.

I'd love to check which firmware it is, yet we are stuck with lack of connection again.


I can't attach app log file for some reason.

There was an issue with one of the firmware versions, which the new firmware fixes. You may have been caught by this problem before the new version was fully updated and that causes the BTV module in the battery to become unresponsive and as a result, the SmallBMS loses communication with the battery, which in turn leads to the error message.

However, there is a good chance it will resolve itself, but it may take some time...up to 48 hours.

The only solution we found is unfortunately replacement of whole PCB inside the battery.
