Floating vs Storage Voltage Question
Moved this from another thread to open the topic generally. Question was if PD converters with the 13.2 storage voltage were compatible with floating voltage specs at 13.5 and above. ---------------...

ISTR a debate over whether you should float Li batts. When not in use (storage?) they should be at around 60% SOC. (true?) RV use does not seem to be covered by the float or not guidelines for any battery type seems like. Keeps the battery makers happy I suppose.
I don't have any data for how much it would cost an RVer to float when ideally he should not be floating. Just part of doing business, so why worry about it?
As far as lfp goes if I was putting my rv away for winter or a long period of no use the batteries would be at a 50-60% SoC. Plus I would remove all the senseboards connected to the cells, they're part of the bms. They have a power draw on the cells, very little but it's still there.
If the rv was being stored with occasionally use and no hookups I would just shut everything down turn the batteries off and disconnect the solar (breaker). If the batteries are somewhere above 50% SOC good enough.
This is what I would do for "my" system today if the storage scenario came up.
