Lithium batteries have the added bonus of not containing the heavier lead-acid found in AGM’s, therefore , are much lighter . Since their DOD is 80-90%, lithium a battery bank generally occupies less space.lithium batteries can save quite a bit of volume and weight in comparison to the traditional AGM’s.
