Sounds like an engineering challenge to me... if it hasn't been answered "open source" before I get to that step, one that I might take on... A flexible design that is "quiet" and treat the LiFePO battery(ies) as they "need" for maximal lifespan, and allowing them to be used for operation w/ "float", and/or standard charging... CC/CV charging PLUS.
