ECTIVE LC 100 Marine LT 12V vs ECTIVE LC 300L LT 12V
Technical comparison · Lithium batteries for campers
Same voltage, 12 V, the same five-year warranty and cold-charge protection on both: what changes is size and where the battery can sit. The Marine is IP67 and 100 Ah, the 300L offers 300 Ah but is IP65 and weighs 37.5 kg against 13.5.

The differences that matter
Figures as declared by the manufacturer.
- 100 Ah vs 300 Ah, 13.5 kg vs 37.5 kg → the 300L has far more reserve, but it takes two people to move.
- Discharge 150 A vs 200 A, charge 100 A vs 150 A → the current gap is smaller than the capacity gap: the Marine is not as limited in loads as its size suggests.
- IP67 vs IP65 → the Marine is the choice for a spot exposed to water; the 300L goes in a sheltered compartment.
- Length 30.8 cm vs 52 cm → the Marine fits a tight space, the 300L needs a long compartment.
Which one to choose
Choose ECTIVE LC 100 Marine LT 12V if…
the spot is exposed or damp, on a boat for example: IP67, discharge up to 150 A and charging up to 100 A in 13.5 kg. You accept a reserve of only 100 Ah.
Choose ECTIVE LC 300L LT 12V if…
you need a large reserve and the battery sits in a sheltered compartment: 300 Ah, discharge up to 200 A, charging up to 150 A. You pay for it with 37.5 kg, 52 cm of length and an IP65 rating instead of IP67.
