ECTIVE LC 280s LT Underseat vs ECTIVE LC 50L BT 24V
Technical comparison · Lithium batteries for campers
One is a 12 V battery, the other a 24 V one, so the voltage of the onboard system settles the question before anything else. Only after that does the real difference come in: 280 Ah against 50 Ah.

The differences that matter
Figures as declared by the manufacturer.
- 12 V vs 24 V → the two are not interchangeable; the choice follows the system already in the vehicle.
- 280 Ah vs 50 Ah, 28 kg vs 12.3 kg → a far larger reserve, but a heavy battery that needs a fixed, planned spot.
- Discharge up to 350 A vs 50 A → only the first suits high-current loads; the second is for light circuits.
- IP21 vs IP65, cold-charge protection yes vs no → the 280s wants a dry compartment but protects the cells when charging in the cold; the 50L stands up better to the weather but lacks that protection.
Which one to choose
Choose ECTIVE LC 280s LT Underseat if…
you run a 12 V system sized for heavy, sustained loads: 280 Ah, with discharge up to 350 A and charging up to 200 A, plus seven years of warranty. You accept 28 kg and an IP21 rating, which means a protected interior compartment.
Choose ECTIVE LC 50L BT 24V if…
your system is 24 V and the loads are modest: 50 Ah, up to 50 A in both directions. At 12.3 kg and IP65 it is easy to move and can go in less sheltered spots. The trade-off is a much smaller reserve and no cold-charge protection, which the 280s has.
