Hello,
I have 4 new 12V 100ah lithium batteries I bought about 7 months ago and haven't used yet (to make a 24V 200ah combination), that I am getting close to being ready to connect up to a solar generator I have been putting together. However one of the batteries has suddenly dropped down to 4V, and the display on it won't light up. The other 3 are still fine with about 83 or so % charge and 13+ volts. Does it just need charging or is it likely faulty? It is frustrating as I was getting close to connecting everything up.
I don't have a lithium battery charger either, only a 'normal' charger you would charge up something like a car battery with, which from what I have read you shouldn't use with lithium batteries.
