I’ve got several drivers lying around for builds I wanted to start early last year and have yet to get around to it so I know what you mean :/Lots of small stuff, mostly and yes, too much, I won't live long enough to build all of this stuff with as much time as work is taking from me, especially now, on the other side of the planet from my goodies.
Max input voltage would be 6.4V (2x LiFePO4 at full charged = 3.2V*, for example ANR26650M1B cell)
Max output voltage (Vf) would be 6V
Above that? kaboom!
*please note that some LiFePO4 is 3.5~3.6V at full charged
