How does it work? I have setup the capacity to 280Ah, but the bms triggers low voltage protection when there are around 25Ah left, so it should show 91% SoH.
Has the ‘rated capacity’ or ‘battery capcity’ displayed changed for you?
Do you regularly hit the low voltage protection by any chance?

No, I think it is calculated by resistance and efficienty of the cells and pack, yet haven't got that confirmed
This pack was cycled from 100% - 15% daily for 4,5 years, haven't been regularly cycled the last couple of years.
Got them used, out of planes, so who know what happened in cycling terms before

Hello, I cannot connect to the Seplos BMS via Bluetooth. On smartphones and tablets, Seplos BMS is not displayed in the Bluetooth settings. The built-in Neey BMS is displayed in the Bluetooth settings on the smartphone and tablet.
Is there a solution?
Thanks for the help.

You need to use the proper app for your BMS..
V2 and V3 use w different app, both can be downloaded directly from the seplos site , after registration

Thanks for the support.
I use V3.
A connection with the Seplos app via Bluetooth is probably only possible if the RS 485 connection between the inverter and batteries is separated.
Or is there another option?

What is the best way to set the parameters in the Seplos BMS?
I use Growatt SPF 5000 ES in parallel operation off grid with two batteries with Seplos BMS V3.0 and Neey BMS.
Thanks

I believe you can only change the V3 setting through the windows software and a rs485 connection.
The bluetooth i think is monitoring only

Well this has taken a while but I have an update. Fogstar did not reply or respond or offer any kind of help, useless.
Separately to this I sent my original BMS to Seplos for re-programming. This took ages until last week they sent it.....to the wrong person. It is now with some random who knows where. But its OK at least postage was only about 50 sodding pounds. Also useless
Finally I bought a new PCB from Fogstar as I didn't have much choice (the enclosure is for the Seplos BMS). Funnily enough they took the money quickly and dispatched the new PCB which is now working........
One day I will get the original BMS back and be able to get on with my life but thus far underwhelmed by the customer service and firmware quality.
