ECTIVE LC 320s LT Underseat vs Liontron LX Smart 12,8 V 200 Ah Arctic Marine
Technical comparison · Lithium batteries for campers
Same voltage, 12 V, but two different ideas: the ECTIVE LC 320s LT Underseat puts 320 Ah and 200 A in a single block, the Liontron 200 Ah Arctic Marine bets on IP67 and a 10-year warranty. Where the battery is fitted matters as much as capacity.

The differences that matter
- Capacity: 320 Ah versus 200 Ah → beyond 200 Ah the Liontron needs a second battery, the ECTIVE does not.
- Maximum current: 200 A versus 150 A, discharge and charge → if loads or charging exceed 150 A, the Liontron is the limit.
- Protection: IP21 versus IP67 → the Liontron also tolerates water, the ECTIVE must be kept sheltered.
- Warranty: 7 years versus 10 → three more years of cover with the Liontron.
Which one to choose
Choose ECTIVE LC 320s LT Underseat if…
your 12 V system has heavy consumption and you want 320 Ah, about 4.1 kWh, in one battery rather than two in parallel. You accept IP21, so a dry compartment, 32 kg and a declared warranty of 7 years instead of 10.
Choose Liontron LX Smart 12,8 V 200 Ah Arctic Marine if…
the battery sits where damp or water can reach it and 200 Ah is enough: IP67, 25.8 kg, a declared 10-year warranty. You accept 120 Ah less and a maximum current of 150 A instead of 200 A.
