As the other commenter said, it's all about depth of discharge. A 10kWh Lifepo4 bank gets you almost 10kWh every time while you should treat a 10kWh lead-acid bank as if it was a 2kWh bank for any sort of decent life, with deep discharges being limited to emergency situations.
All lithium chemistries are practically maintenance free while you are probably familiar with water level monitoring and equalization of lead acid.
Note that all site built lithium banks MUST have a balance mechanism as this is their "automated maintenance". Without balancing on every charge, lithium cells will be rapidly destroyed.
Good points to note, thank you! I would have taken the balancing circuit for granted, but it doesn't hurt to double-check with vendors.
