The differences that matter
- Ingress protection IP21 vs IP67 → the first must be mounted under cover, the second tolerates an exposed installation.
- Maximum discharge current 350 A vs 150 A → only the first handles loads with heavy draw.
- Height 14.5 cm vs 21.5 cm → the first fits a low space, under a seat or in a flat locker.
- Warranty 7 years vs 10 → the second stays covered three years longer.
Which one to choose
Choose ECTIVE LC 280s LT Underseat if…
you need to feed heavy loads from a 12 V system and have a dry interior compartment: 280 Ah (3.58 kWh), up to 350 A on discharge and 200 A on charge, in just 14.5 cm of height. The price is the IP21 rating, which asks for a sheltered spot, 28 kg and 7 years of warranty.
Choose Liontron LX Smart 12,8 V 100 Ah Arctic Marine if…
you mount the battery in an exposed spot, such as on a boat: IP67, 15.1 kg and a 10-year warranty. You get 100 Ah and 150 A on discharge, less than half the capacity and maximum current of the other.
