The differences that matter
- 320 Ah vs 150 Ah → at 12 V the first keeps all its capacity in one unit; with the second you need more than one to come close.
- 200 A vs 150 A, discharge and charge → 50 A more through a single battery.
- IP21 vs IP67 → the first only in a sheltered, dry compartment; the second tolerates dust and temporary immersion.
- 7 years vs 10 years of warranty → ECTIVE declares 6,800 cycles but coverage ends at 7 years; Liontron declares 3,000 cycles and stays covered for 10.
Which one to choose
Choose ECTIVE LC 320s LT Underseat if…
you want 320 Ah in one 12 V battery and the compartment is indoors and dry. You accept 32 kg of weight against 19.6 kg, and a rating that is not built for water.
Choose Liontron LX Smart 12,8 V 150 Ah Arctic Marine if…
the battery will sit where it can pick up damp or splashes, or you have to carry it into place by hand: 19.6 kg against 32. You give up some capacity and maximum current, and reaching 320 Ah would take several units.
