How we assign awards →The differences that matter
- Capacity 100 Ah vs 280 Ah; discharge 100 A vs 350 A; charge 100 A vs 200 A → at 12 V that is about 1.2 kW against about 4.2 kW of output; beyond the first figure only the 280s will do, and it accepts up to twice the charging current.
- Warranty 5 years vs 7 → the 280s is covered two years longer.
- IP65 vs IP21 → the 100L tolerates splashes and dust; the 280s has to be mounted where it stays dry.

Which one to choose
Choose ECTIVE LC 100L LT 12V if…
100 Ah is enough for you and you have a narrow, tall space: the 100L takes up 31.8 × 16.5 cm of floor and weighs 12.5 kg, less than half the 280s. In return the reserve is small, with no headroom once use grows.
Choose ECTIVE LC 280s LT Underseat if…
you have a wide, low space such as under a seat and want a large reserve: 280 Ah, 3.584 kWh. You accept 28 kg and IP21 protection, which suits a dry interior compartment rather than one exposed to water.
