Liontron LX Smart 12,8 V 300 Ah Arctic Untersitz vs LiTime 48V 100Ah ComFlex 3U
Technical comparison · Lithium batteries for campers
The two batteries run at different voltages, 12 V and 48 V, so they belong to different systems. At 48 V, 100 Ah is about 4.8 kWh and 100 A is about 4.8 kW; at 12 V, 300 Ah is about 3.6 kWh and 200 A about 2.4 kW (estimates from system voltage; manufacturer-declared values).

The differences that matter
- System voltage: 12 V versus 48 V → decides which system they connect to; they are not interchangeable.
- Energy and current: 300 Ah and 200 A at 12 V versus 100 Ah and 100 A at 48 V → about 3.6 kWh and 2.4 kW versus about 4.8 kWh and 4.8 kW.
- Warranty: 10 years versus 5 years → for the first the limit that comes first is the 3000 cycles, for the second the 5 years.
- Weight and shape: 33.35 kg, 34.9 × 34.9 × 19.1 cm versus 44.9 kg, 44.2 × 48 × 13.3 cm → the second is heavier but lower.
Which one to choose
Choose Liontron LX Smart 12,8 V 300 Ah Arctic Untersitz if…
the system is 12 V and you want 10 years of warranty, with 70 % of capacity guaranteed at the end; the limit that comes first is the declared 3000 cycles. You accept about 3.6 kWh and about 2.4 kW of maximum current, in a body of 34.9 × 34.9 × 19.1 cm weighing 33.35 kg.
Choose LiTime 48V 100Ah ComFlex 3U if…
the system is 48 V and you need more power: about 4.8 kWh and about 4.8 kW, with 4000 declared cycles. The trade-off is a 5-year warranty, 44.9 kg and a body of 44.2 × 48 × 13.3 cm; it cannot connect to a 12 V system.
