Lithium Vs. More Solar
Having learned so much from members here since my initial posts in early 2018, I've been grateful that the learning curve has been relatively steady, and informative. I've truly appreciated the guidan...

Hi BFl13,
You are assuming the battery management system is identical for different amp-hour capacities. I'm not convinced that is so.
Balance and capacity still matters because we wish draw equally from the well--not take one battery down faster which is exactly what happens with unbalanced wiring.
I thought i was clear that balanced wiring is necessary to get a 24 and a 27 to rise and fall in SOC together.
What I was asking is if you had a same brand so same BMS design, in a Li of say 100AH in parallel with a 200AH one, and wired in a balanced manner, why would they not rise and fall together?
In fact who cares if they don't, since Lis don't care what SOC they are at and not full. If one got way low and the other had lots left in it, the low one would be protected by its low point shut off and the other would do the work till it got low. ?
On recharging if one got to the BMS stage first won't the other just keep getting recharged till it gets there? If you keep charging while the first one is doing its BMS, what bad thing happens? With FLAs, the bad thing is it gets overcharged or the other one never gets to full when charging is stopped because the first one is full.
But don't Lis act differently when reaching full?
