ECTIVE LC 120 Dual 12V vs LiTime 48V 100Ah ComFlex 3U
Technical comparison · Lithium batteries for campers
These two LFP batteries are not interchangeable: one works at 12 V, the other at 48 V, so the choice follows the system you already have. Amp-hour figures (120 against 100) cannot be compared across different voltages, and all values are manufacturer-declared.

The differences that matter
- System voltage 12 V vs 48 V → they do not swap: the system you have decides, not the spec sheet.
- Weight 10.2 kg vs 44.9 kg → the second needs a mounting surface that carries around 45 kg.
- Height 19 cm vs 13.3 cm → the first fits a narrow, tall compartment, the second a wide, low one.
- Declared cycles 2,000 vs 4,000 → with a 5-year warranty on both, the reference lifespan is the same, so the 4,000 should not be counted on.
Which one to choose
Choose ECTIVE LC 120 Dual 12V if…
you run a 12 V system in a camper or boat with little room: 10.2 kg in a 31.5 × 17.5 × 19 cm case, rated for 120 A on both discharge and charge. The trade-off is 2,000 declared cycles, half of the other battery's, although with a 5-year warranty on both the reference lifespan is the same 1,825 cycles.
Choose LiTime 48V 100Ah ComFlex 3U if…
your system runs at 48 V and you have a wide, low space: 13.3 cm high, but 48 cm deep and 44.9 kg to support. You give up 12 V compatibility and the low weight, and the declared maximum current stays at 100 A.
