ECTIVE LC 120 Slim LT 12V vs ECTIVE LC 80 LT 12V
Technical comparison · Lithium batteries for campers
Two 12 V lithium batteries for campers with the same 5-year warranty: one is built around capacity and high currents, the other around low weight and a higher ingress rating. What decides it is the battery compartment: how much space and how much weight it can take.

The differences that matter
- 120 Ah vs 80 Ah → a reserve one and a half times larger: time away from charging lasts longer.
- Charge up to 100 A vs 40 A → with a suitable charger the 120 Slim refills faster; the 80 LT stays capped at 40 A.
- Discharge up to 250 A vs 100 A → the 120 Slim can run more powerful loads at once before it hits its limit.
- 19.9 kg and IP55 vs 10.2 kg and IP65 → the 80 LT is easier to carry and fit, and has the higher ingress rating.

Which one to choose
Choose ECTIVE LC 120 Slim LT 12V if…
you need a single house battery that carries you through several days away from hook-up and can take high charge currents. The trade-off is a narrow but long body (12.6 × 46.6 × 29 cm) that needs a flat spot, and a weight that makes installation harder work.
Choose ECTIVE LC 80 LT 12V if…
the compartment is small or the battery gets removed now and then, and your usage looks like a weekend rather than a full week. You give up part of the capacity and the higher currents, both on discharge and on charge.
