Ok, I am still declaring myself a newbie,
So will have to put up with me, and likely my more obtuse follow up questions:
Here is what I have:
4, 280 amp eve cells.
Top balanced them
Knocked their voltage down a bit to "normal, happy voltage - 3.2? don't remember
Overkill BMS, 12V, 120 amps
Android phone to connect
~ 2 weeks later, put them into my bus
4, 100 watt solar panels, all hooked up to Victron 100/50 mppt
Hooked up BMS etc.
This was a drawn out project
When I got around to it, noticed the BMS is showing the cells to be at about 50% charge, based on the icons,
which they do at this moment. ( I know the icons are qualitative, not too accurate).
The voltages of the cells right now are 3.333V +/- .001
As I never knocked the cells further down after top balancing them, are they really at approx 50% SOC, or more like 80%? -
Can the BMS tell somehow?
Is there something the Overkill BMS does to drive them down/up to 50%?
Is there something I have to do?
I will stop here for now for the questions..
Thanks you very much.
