OK, so I know that normally you can't connect buck converters in series because it's creates a a short, and even in parallel it's somewhat risky because whichever one has the higher voltage will usually get all or almost all of the load. But here's what I'm wondering: buck converters, but the inputs are in series? So batt neg to buck1 neg, buck1 pos to buck2 neg, buck2 pos to batter pos, then the outputs of these in parallel? Again, I know you're not normally supposed to put them in parallel, but if they're adjustable then I can dial in the voltage outputs until they're basically identical and it should work OK...I hope.
