Newbie question .
I have a 100ah 12v lithium battery to run a fridge in the back of my car. It is used infrequently and taken out of the car when not in use. It can charge in the car with a DC-DC charger and I have a 15A Victron Blue smart charger at home.
I’ve read that lithium batteries, including LFP, last longer if stored and about 50% charge.
Does the charger/app have a profile to keep the battery at, say, 60-70% while not being used, then change the profile to full charge a day or two before being used?
Is that something that is practical or desirable?
