"That has to be a bear to nanage charging (and monitoring discharge levels) "
Surprisingly, "No" - LiFePo batteries are well understood and easily managed and you always use a balance charger/BMS monitoring individual cells.
What hasn't been mentioned is that they're essentially non-flammable - they won't burn if pierced/shorted out and they take a LOT of persuasion to burn at all - this plus the greater endurance is why they've been gaining in popularity despite the slightly lower energy density.
