I own an Travel Trailer and need to upgrade the battery in it. The cheapo lead acid battery is no longer cutting it. So I've been researching a lot about lithium batteries and I am very interested in building my own using LiFePO4 3.2v cells. Can batteries be put together without using a power supply to ballance the cells before putting them in series? I've watched a few videos where they literally take the cells out of the box, measure the voltage across each, if close they just start putting the them together. I've seen others where they say balancing the cells by connecting them in parallel and applying voltage to them essential.
If ballancing the cells is essential (which I'm thinking) what size is the minum power supply required? I own a 12V DC power supply and I could easily use a adapt it into a variable DC power supply, but it would at most deliver 5 amps.
Does anyone knoow where I can find a site that has written instructions on how to correctly put together lithium battery? I just don't trust the all the videos that are out there, except those from Will Prowse. I'd like to build a 12V battery using 280AH or sightly larger cells.
Your hel[p is appreciated!
