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. ---------------...

Hi BFL13,
I've heard, for greatest longevity, long term storage for Li is 40 to 50% state of charge. Not what I want.
If you are on shore power for a while, you can do that if you have a converter to make your 12v, but not if you have an inverter/charger. (An inverter /charger must be connected to the battery to operate at all--it needs the 12v from the battery to run its own systems)
It might be worth the approx $130 for a converter to rig up and by-pass the inverter/charger for 120v too somehow. If all you have is a single 12v Walmart batt, then it would not be worth the bother probably. What if you have a $3,000 Li battery bank and are spending the winter on shore power at some resort?
Hi BFL13,
I did leave my oem converter in place but unplugged, so I have that covered.
I think it is possible with an inverter/charger to set the charge rate to zero. I may be wrong about that. I have successfully set the maximum charge rate to 111 amps, down from the "flat out" 129 amps design.
I normally leave the solar maintaining my batteries during storage periods.
I chose to have enough solar to equalize the battery bank.
