Say I have 4 large 280AH batteries with a high state of charge, and 4 more with a low SoC.
I assume if I use big busbars and parallel these 8 batteries there could be drama like sparks and possibly even damage to the cells.
I have some 18awg wire, could I safely get around this by just using the thin 18awg wire to parallel the cells, so that the transfer of power is slower, and just wait longer for the 8 cells to come into balance, or could there still be sparks or damage?
Edit:
Adding background information:
I started out charging a 16S pack of 280AH batteries in groups of 4 cells. The problem with that is, after charging 4 separate groups of 4, each group will be at slightly different SoC, so I will need to parallel them at the end anyway.
So I decided rather than charge them in groups of 4, I will just parallel all the cells and charge them as a group.
To do that, I need to lower the SoC of the first group of 4 cells which are at a higher SoC, or combine all the cells "as-is" and them them shock each other into an equal SoC, and I want to do that safely and slowly.
