It is time to replace the lead in my RV. I am heading out in a few weeks to spend the winter dry camping in the Sonoran Desert. I am currently in negotiations with a seller to get another Tesla module so I will have 444 18650 cells to play with. I plan on taking 2 of my 180 watt solar panels which put out 27 volts open circuit with their Mpp at around 17 volts.
I am interested in hearing from anyone who is using a lithium battery in their RV and finding out the specifics of their system. What configuration did they use to assemble the battery, ( 3s or 4 S) and what solar charge controller did they use? If they set it up for 4s (16.8 v full charge) were the RV components able to handle it and survive or was a buck converter needed to drop the voltage to ~13v.
I have, so far, disassembled 3 Tesla modules and put together a few bike batteries but this will be my first go at trying to emulate an old fashioned 12 v deep cycle battery so suggestions are welcome.
