The differences that matter
- 280 Ah vs 80 Ah → more than three times the energy reserve: it sets how many days you stay out without recharging.
- 200 A vs 40 A maximum charge → a strong charger fills the larger one far faster; the smaller one stops at 40 A whatever charger you fit.
- IP21 vs IP65 → the first belongs in a sheltered compartment, the second tolerates an exposed spot.
- 28 kg vs 10.2 kg → weight to fix down and add to the vehicle's payload.
Which one to choose
Choose ECTIVE LC 280s LT Underseat if…
you run a large onboard system for several days away from a hookup and have a charger able to push up to 200 A. The trade-off is 28 kg to place in a dry compartment, since the declared protection is only IP21.
Choose ECTIVE LC 80 LT 12V if…
you are fitting a small system in a van or a light camper and want a 10.2 kg battery that can sit where it may get splashed (IP65). The trade-off is 80 Ah and a 40 A maximum charge current, so it recharges slowly and leaves little margin if you add loads.
