OK, Here we delve into territory that is currently over my head. I have read some great articles discussing "the knee" and what Lithium will tolerate / prefer, but really dont understand this yet. I am determined to, however.Figuring out your peak charge rates is necessary to determine your cell balance needs. Higher rates mean more balancing current. Though if you stay out of the knee at above 98%, your balance current drops pretty quick. Nothing wrong with 24V, you just cut your wiring sizes by half, and choose components that are 24V. Lots of boats, big RVs, and small aircraft use 24V, so finding parts won't be hard.
Knowing your peak current (charge and discharge) is necessary for choosing wire sizes, inverter capacities etc.
Of course, I assumed that once settled on some reasonable guidelines, I would need to hone in on the actual use and needs to make sure I am sizing connections and protection devices appropriately. I figured I would focus on the plan / major components first to understand the systems and then get down to the nitty gritty. Like it has been said already, might be back-asswards from an engineers POV, but it's how I think.
