The differences that matter
Values declared by the manufacturer. - Discharge 350 A vs 150 A → the first can feed high-draw loads continuously; with the second you keep those loads below its limit. - IP21 vs IP67 → the first wants a dry interior compartment; the second can sit in a boat locker or anywhere it gets splashed. - Height 14.5 cm vs 25.8 cm → only the first fits under a low bench or seat. - Warranty 7 years vs 10 → the first's warranty ends before its cycles do; the second states a guaranteed remaining capacity at the end of the warranty.
Which one to choose
Choose ECTIVE LC 280s LT Underseat if…
you have a van or camper where the battery has to slide under a bench and the loads draw a lot of current. You accept a dry interior compartment, 28 kg and a shorter warranty.
Choose Liontron LX Smart 12,8 V 200 Ah Arctic Marine if…
the battery goes in a boat locker or a compartment where damp gets in, and your loads stay within 150 A. You give up the extra current and capacity, and at 25.8 cm tall it will not go under a low bench.
