How we assign awards →No awards in this tier.
The differences that matter
- Protection → IP21 against IP65: the ECTIVE goes in a compartment that stays dry.
- Discharge current → 350 A against 200 A, about 4.2 kW against about 2.4 kW at 12 V: matters if you feed a powerful inverter.
- Warranty → 7 years against 10, with 70% of capacity guaranteed on the Liontron at the end.
- Height → 14.5 cm against 19.1 cm: decides whether it fits the compartment. Manufacturer-declared values.
Which one to choose
Choose ECTIVE LC 280s LT Underseat if…
The compartment is low and dry, and the inverter pulls heavy loads: the ECTIVE is 14.5 cm tall and discharges up to 350 A, about 4.2 kW at 12 V. The trade-off is IP21 protection, which restricts it to a compartment shielded from water, and a 7-year warranty instead of 10.
Choose Liontron LX Smart 12,8 V 300 Ah Arctic Untersitz if…
The installation is somewhere water can reach and you want a long warranty: the Liontron is IP65, with 10 years and 70% of capacity guaranteed at the end of the warranty. It discharges up to 200 A (about 2.4 kW at 12 V), stands 19.1 cm tall and weighs 33.35 kg.
