The only way to have a physically smaller bank with the same amount of energy, is to use Li batteries.
common misconception
Lithium will weigh less, but for the same
total AmpHrs, it will be very close in space used as lead acid
now if you want to talk ampHrs cycled, and discharge the lithium bank to 20% SOC
you '
can' have a smaller size lithium bank with the same 'safely cyclible' number of ampHrs as a larger lead acid bank
but it won't be the same 'total capacity' from full to zero SOC
example (2) grp27 lead acid 105 amphrs batteries 210 amphr total
105amphr to 50%
are the same physical size as (2) lithium 100ampHr batteries 200amphr total
160 amphr to 20% SOC and the lithium weigh a lot less
for the same 'total capacity' Li has more usable(aka safely cyclable) power for the same space, less weight,
BUT not physically smaller for the same 'total amphr capacity'
(3) 105 amp hr lead acid give 150Amphrs to 50%
take more space, weigh more, but have 50% more total power capacity in a run dead use it all emg situation ( its cold the heaters on and there is no gas for the genny, or it won't start for some reason}
