lithium question
Can you charge lithium batteries with a regular charger or do I need to buy a special charger?

Interesting about the Tesla, thanks. What about voltage to the 7-pin and the camping 12v sockets? You can run things at 12v, but actual battery charging requires more like 14v or so.
With a gasser, you use the DC-DC to boost the engine battery voltage from 13.8ish to 14.6ish. Charging at 13.8 is lame. The Tesla might only be giving you 12.6ish or whatever to run your camping things and the 7-pin for trailer signal lights?
Sounds like the portable gen is going to get a lot of work!
Our present tesla (Model 3) doesn’t have a 7 pin so no way to check what’s on the charge line. Our model Y delivery date is tentatively February so have to wait till then to check.
We don’t dry camp a lot but when we do it’s usually for a week....and under trees. I suspect I would have to run the genny at least once a day for 45 minutes. Maybe twice a day depending how cold it is as the hydronic heating system has a pump that draws a couple or so amps when called on. Then again. A fantastic fan does as well. We’ll have to wait and see.
I’m looking at a victron dc to dc 9 amp converter so I don’t have a double conversion. I received a tip on how to run camp mode in a lower current draw mode. I’m running a test on it right now. Gotta do something until we can go camping. :).
