If this has been discussed before I would love a link to the discussion ... I couldn't find it with several searches I tried.
With LiFePo4 batteries what is the preferred resting SoC for a battery backup system ?
Should I be cycling the battery every X days down to a certain SoC and then allowing it to charge back up?
I have a battery backup system in place, the SoC is currently 100% (as discovered / set by my BMS bypassing at 3.5vdc ... the actual voltage at the cell is likely closer to 3.475-3.48)
When I had my electric motorcycle the preferred SoC for a resting bike was 80% and we were only suppose to peak above 90% if we were going to instantly start riding the bike but most of us charged to 90% because it took too long to get the last 10%
This battery will be migrated into an off grid house we are building in the future but right now it is being used as an always on battery backup system (general diagram at first post here https://diysolarforum.com/threads/i...or-battery-bank-and-sma-si-load-center.52698/ )
It will likely be used as a battery backup for at least another year before it is installed in the new off grid home.
Thoughts? Feelings? Mystical voodoo? All welcome.
