ECTIVE LC 320s LT Underseat vs LiTime 48V 100Ah ComFlex 3U
Technical comparison · Lithium batteries for campers
Both are batteries in the range of several kWh, but one runs at 12 V and the other at 48 V: they belong to different systems and cannot be swapped. The voltage you have decides; space comes next.

The differences that matter
- 12 V against 48 V (manufacturer-declared values) → different systems: the choice follows the voltage you have.
- 200 A at 12 V against 100 A at 48 V → in theory about 2.6 kW against 4.8 kW (nominal voltage times maximum current): a higher voltage needs less current for the same power.
- 32 kg, 35.5 × 22.4 × 19 cm against 44.9 kg, 44.2 × 48 × 13.3 cm → a taller, narrower shape against a low, wide one: it depends on the compartment.
- 7 years and 6,800 declared cycles against 5 years and 4,000 → the ECTIVE has the longer warranty and more declared cycles.
Which one to choose
Choose ECTIVE LC 320s LT Underseat if…
you have a 12 V system and want 320 Ah, about 4.1 kWh, in a 32 kg block 19 cm high, built to sit under a seat. It handles up to 200 A, carries a 7-year warranty and 6,800 declared cycles, and is controlled over Bluetooth. The trade-off: its protection rating is only IP21.
Choose LiTime 48V 100Ah ComFlex 3U if…
you have a 48 V system and want a 100 Ah battery in a flat format, 44.2 × 48 cm and 13.3 cm high. The trade-off: it weighs 44.9 kg, the warranty is 5 years, declared cycles are 4,000 and maximum current is 100 A.
