ECTIVE LC 100L BT 12V vs ECTIVE LC 280s LT Underseat
Technical comparison · Lithium batteries for campers
Two 12 V batteries, one of 100 Ah and one of 280 Ah: the choice is about how much reserve and current you need, more than about voltage. The larger one wants a protected interior compartment, the smaller one tolerates a less sheltered position.

How we assign awards →The differences that matter
Figures as declared by the manufacturer.
- 100 Ah vs 280 Ah, 12.5 kg vs 28 kg → the 280s gives far more reserve, but it is a battery you install once and leave where it is.
- Discharge 100 A vs 350 A, charge 100 A vs 200 A → the 100L limits which loads you can connect and how fast it recharges from a powerful source.
- IP65 vs IP21 → the 100L tolerates a less sheltered position; the 280s wants a protected compartment.
- Cold-charge protection no vs yes, warranty 5 vs 7 years → the 280s protects the cells when charging in winter and covers two more years.
Which one to choose
Choose ECTIVE LC 100L BT 12V if…
you have a light 12 V system, for which 100 Ah and 100 A discharge and charge are enough. It weighs 12.5 kg, is IP65 and can go in less protected spaces. You give up most of the reserve and the cold-charge protection the other one has.
Choose ECTIVE LC 280s LT Underseat if…
your 12 V system is large and the loads are high: 280 Ah, discharge up to 350 A, charging up to 200 A, seven years of warranty against five. You accept 28 kg and an IP21 rating: the battery goes in a protected interior compartment.
