The differences that matter
- 320 Ah vs 100 Ah → far more energy in one battery, and headroom for more loads together
- 32 kg vs 15.1 kg → the second can be moved and fitted by one person
- IP21 vs IP67 → the first wants a dry compartment; the second tolerates a less sheltered one
- 7 years vs 10 years of warranty → on both it ends before the declared cycles do; the second gives you three more years
Which one to choose
Choose ECTIVE LC 320s LT Underseat if…
you live aboard and want one large bank under the seat, to keep many loads running together. The trade-off is the weight to fix in place, a compartment that has to stay dry, and a shorter warranty.
Choose Liontron LX Smart 12,8 V 100 Ah Arctic Marine if…
you use the vehicle at weekends, a modest reserve is enough and you want a battery one person can move without effort, even in an exposed compartment. The trade-off is capacity, under a third of the other: once it is used up, you need to recharge.
