convert to kWh. compare kWh. then Ah/voltage doesn't matter.
Also remember practical capacity - li-ion drawdown regularly to 20%, charge up to 80%, rinse and repeat, SoC doesn't matter in that range.
lead acid likes to sit at 100% SoC, doesn't like regular drawdowns past 50%. so for a battery you are going to exercise regularly, lead acid should be 2x the size of the li-ion battery in kWh.
