i don’t disagree, my point is if you have the means lithium systems are fantastic. We consume power heavily also and I had the means to install the system I have. Is it for everybody no, it’s a large investment and requires good technical knowledge or you will pay even more for a good reliable system.
My point about about solar input is we can stay in bulk until the battery is full, it’s doesn’t take hours of absorption of reach 100%. My previous AGM batteries would take all day to reach 100% due to the charging nature of that chemistry.
My setup never gets below 70% state of charge, so it’s overkill off course, but why not it’s the Australian way!
I just wanted to clarify one point, i dont really like BMWs ... i have a Troopy, so im clearly not up for a performance vehicle debate, i just used bluff with that angle

I suspect we'll all likely transition to lithium eventually. I agree partly with
@Boots in Action in thats its generally a relatively low percentage cost, but only if it came packaged in the van purchase. $6000 or $4000 for "anything" stand alone is significant to me, and requires lots and lots of thought, procrastination and justification
Like all new tech, its the pioneers like yourself, that jump on it in its infancy, that ultimately will help to make it affordable and maintream for the reluctant peasants like me.
I can see the fantastic benefits such as induction cookers, running the aircon for short periods and of course compressor fridges ....
