Technical comparison · Lithium batteries for campers
They do not do the same job: the ECTIVE is a 120 Ah battery for a 12 V system, the Liontron a small 24 V, 20 Ah unit weighing 5.95 kg. The choice follows the system and the load, not a head-to-head.

The differences that matter
- 120 Ah and 120 A at 12 V against 20 Ah and 20 A at 24 V (manufacturer-declared values) → in theory about 1.5 kWh against 0.5 kWh (nominal voltage times capacity): these are batteries of different sizes.
- 10.2 kg against 5.95 kg → the second can be carried and fitted almost anywhere, the first needs more room.
- Cold-charge protection: yes against no → in a compartment that drops below freezing, only the ECTIVE declares it.
- 5 years and 2,000 declared cycles against 10 years and 3,000 → the Liontron has the longer warranty and more cycles, on a much smaller capacity.
