Hmmmm...but if it DID fail, don't you think you'd be able to pull the battery out (easily the most expensive sub-component) and then build another power box around it, using higher quality components?In my research (before I built my own) the Goal Zero 500X, and the Dometic LiFePO4 units were the best options with the Jackery being the most affordable but not as feature rich. They all (in the $400-800 price point) suffered from slow DC-DC and/or AC-DC charge rates. And they all had a sub 2-3 year warranty which is a joke for a lithium based system that will last you a long time (so you are on your own if any of the components around the battery develops a fault).
I mean, take the Jackery, for instance, which sells for what, $450? It comes with a 24AH Li battery.
I wonder what kind of LiFePo battery the boxes like the Goal Zero or Jackery use. Does anyone know?
So if you buy one of these packs, use it for a couple of years and even if a major component fails after it's OOW, worst case scenario you still have a couple hundred dollars worth of battery for your next build, right?
