Technical comparison · Lithium batteries for campers

In brief

Same voltage, two uses: the Marine holds about 1.28 kWh and is rated IP67, the 280s about 3.58 kWh but only IP21. Before capacity, what decides is where the battery lives: somewhere exposed to water, or in a dry compartment. All figures are manufacturer-declared values.

The differences that matter

  • 1.28 vs 3.58 kWh → the 280s holds almost three times the energy; the Marine suits small loads.
  • Discharge 150 A vs 350 A, charge 100 A vs 200 A → at 12 V about 1,800 W vs 4,200 W in theory on discharge: only the 280s feeds large loads.
  • IP67 vs IP21 → the Marine tolerates water; the 280s must be kept dry.
  • Warranty 5 vs 7 years, 13.5 vs 28 kg → the 280s is covered longer but weighs more than twice as much.

Which one to choose

Choose ECTIVE LC 100 Marine LT 12V if…

the battery has to sit in a damp environment and your loads are modest. The compromise is runtime: you carry a little over a third of the other one's energy.

Choose ECTIVE LC 280s LT Underseat if…

you have a dry compartment, even a low one (the battery is only 14.5 cm tall), and you want a lot of energy and current in one block. The compromise is weight and minimal protection: it has to be kept dry.
