One thing to keep in mind and that is, a solid state battery (lithium or derivitave) can be discharged way below 50% with no issues. A conventional battery below 50% starts gassing off and producing lead sulfate which kills the battery
That is the big advantage to a Li-I or Li-Iron phosfate battery they don't produce lead sulfate which kills conventional batteries. That and unit weight.
Why I run an accurate battery monitor and not the bargain basement monitor camper builders install that tells nothing.
Unless you run a Trimetric or a Seelevel you have no idea of your battery condition or state of charge.
