The differences that matter
Values declared by the manufacturer. - 12 V vs 48 V → each connects only to a system of its own voltage; they do not substitute for one another. - Discharge 350 A and charge 200 A vs 100 A and 100 A → the LiTime's limits are much lower, but they have to be read together with its 48 V. - Warranty 7 years vs 5 → the LiTime's 4000 declared cycles outlast its five-year warranty, which ends first. - 28 kg vs 44.9 kg at the same height → the LiTime is much wider and deeper and weighs almost twice as much.
