Here is a good video about charging manually as well. Eventually you want to get everything down to the cell level and automatic, but you can at least get rolling cost effectively, and 18 cells is more manageable manually than others

The leaf cells are a bit trickier than the lifepo4 cells fyi, they might not be as resistant to overcharging, and the special voltages of the leaf cell are limiting your cost-effective bms and charger options, so you might want to consider lifepo4 too.
I was looking at the (recommended to me for the leaf batteries) the Elcon 2500 charger, which can be programmed by the supplier. So I'm getting recommended charging programs from the battery supplier.

I'm still just concerned with the BMS. I'm uneasy about the DIY route because of time and my experience with frying electronics. But I can't find any good affordable BMS systems otherwise.
