Smart Lithium problem after firmware update

I don't know if anyone else has had this problem, i updated the firmware on my smart lithium batteries (mandatory updates V1.24) through the Victron Connect App, all of which were working perfectly before, now some of them even though the firmware stated completed, now come up with a E-SL24 hardware failure alarm and a E-SL2 internal communications failure, the recommendation is to reinstall the firmware to reset the controllers but you cannot do this as the App states "your product is already running the latest firmware version"...

The batteries are:-

24V 200AH smart LiFeP04

12V 90AH smart LiFeP04

Any ideas as i do not want have to replace these perfectly good batteries.

Regards


Steve

Hi Steve, There is a new feature to restart the controller. It is on the Productinfo page of your battery on VictronConnect.

Regards, Roland

Thank you for your answer rjacobs that still does not fix the issue, i have checked into the hardware a bit more and it seems as if the bluetooth module which handles the comms to the slave BMS boards has stopped sending any data requests (regular comms pulses) which the working batteries are sending.

Regards

Steve

You get a fix for this yet? My sys is completely down still and we have a trip coming us. I hate that they have forced updates like this.

I am told by Victron there is a bug (error) in the latest firmware update that is responsible for these problems. As I understand it the firmware in error was the smart dongle firmware so any device that uses the smart dongle to commumicate with the Victron Connect App will expereice issues. My multiplus uses the dongle and I am getting "Unknow" and "Fault" messages displayed. I will never again update my Victron Connect App for at least 2 months following a new firmware update thereby giving Victron time to fix any possible issues. I choose not to be a beta tester for their firmware!

Hi @rwcran , I’m not sure this is related to the request from the Original Poster


with regards to your problem: is it solved already? Or discussed somewhere so I can check?

Same issue here. Tried to restart controller, Failed. Tried to restore back to old firmware by downloading over bup file in connect app. After applying old update, It then forces me to reapply new update. Went ahead and applied again, same result. I am running 2 of the 24v batteries. One updated fine. Other failed.2021-07-06 09.12.26.jpg

Same error codes, E-SL24 and E-SL2, but in my case the battery arrived like this. After trying a firmware update, resetting the controller and even disconnecting power to the controller, the dealer was advised by Victron to replace the battery under warranty. I received a new battery but also have the original battery that seems destined for the recycler - which is just so wasteful. Anyone have any ideas for how to avoid disposing of this battery? Can a new controller board be purchased or the cells repurposed?
