Dear all, I’ve just bought a LiFePO4 battery for my van solar system and I want to make sure it lasts as long as possible. One of the main ways of doing this, if I understand correctly, is to have it stay in the range of 25-75% charge. On the lower end, I have a Battery Protect which I will simply configure to cut-off at 25%. My question is thus; how do I find out which voltage is equal to 100% and which voltage is 0%? Secondly, how do I configure my charge controller so that it stops charging at whichever voltage is equal to 75%? If it’s of any help, I attach both the battery specs from the manual and the options I have on the charge controller. Forgive me if this is basic, I tried researching but to no avail, mainly because I don’t really know what to look for. Many thanks.
