Hi, i developed a Script based on your code that can turn on switchable sockets if the SOC is high. I hope its OK i created a Github Project. https://github.com/christian1980nrw/DR-JC03-RS485-Switcher/tree/main Regards Christian

Please ask your seller about the update to BMS firmware 2.0.0 I had the same problems with version 1.0.3.

I have got the same problem, but if i use maximum charging voltage of 55.2V the alarms are only seldom and it is charging up to 99-100%. I think it needs some months until it is balancing the cells itself.

Hey guys, i was reading some of you are using the Actii Hot Water Controller together with the Photo Booster. I got mine today. If you look at the connectors of the Foto Booster, one side has a diode and one is without. Which side is in and which is out? Thanks.

I think the SOC display is a bit buggy with these batterys, especially if a full cycle is a bit ago. You should ask your dealer if you have the latest firmware. With older firmwares there was also a bigger SOC-Jump. But even with latest software, I think its better to work with the voltages.

If the BMS is not showing the software version, you probably tried to install the wrong firmware or the seller sent you accidently the wrong file. In my case the seller installed a new bootloader first and after that the correct firmware. It was done by teamviewer. Since this BMS rescue...

It still has to be researched and figured out how to use this BMS to get alarms from, charge cycle history and charge current control management (CCCM). I have two different batteries and one is readable, the other not out of unknown reasons, i am still testing. The readable one shows "DR-POWER"...

Yes, please share it. How old is the file? Christian

It will take time because i have to build this first: Link Link2 I am collecting the things and start the projekt next year.
