Switching to Lithium Ion Battery Bank?
I'm toying around with replacing my current 300AH 6v Lifeline AGM batteries wired in series with a Lithium Ion Battery pack. The cost is certainly a lot higher and maybe I'm just looking for trouble b...

I am considering building my own battery pack (seems like an interesting project that isn't beyond the reach of my abilities) but sourcing good cells for a good price appears to be hit and miss.
Be careful what you are doing !
There are 2 basic chemistries used in Li-Ion cells, lithium iron phosphate and lithium cobalt oxide (there are DOZENS of variation on both). LiFe cell is what is used in most heavy duty application (except Tesla) because they are INHERENTLY SAFER ! Their capacity and voltage is lower but they can NOT be overcharged or over discharged to a catastrophe. LiCo cell will EXPLODE AND BURN if over charged or over discharged.
The only way to obtain "inexpensive" batteries is from a wrecked Tesla or a lot used laptop battery packs.
The BEST Li-Ion cells are made by Panasonic/Sano/Tesla, LG or Sony. If you want to "roll your own" you have a lot to learn about charging, discharging, cooling balancing and battery capacity. I am not saying it can't be done, but it will take time testing cells.
