ECTIVE LC 50L BT 24V vs LiTime 48V 100Ah ComFlex 3U
Technical comparison · Lithium batteries for campers
These are two LFP batteries for different systems: one runs at 24 V, the other at 48 V, and neither can stand in for the other. The voltage of the system you have, or are designing, settles the choice; capacity comes second.

The differences that matter
- 24 V against 48 V (manufacturer-declared values) → two different systems; picking one means you cannot use the other without changing what surrounds it.
- 50 Ah at 24 V against 100 Ah at 48 V → in theory 1.2 kWh against 4.8 kWh (nominal voltage times capacity): the gap is how long the same load keeps running.
- Cold-charge protection, absent against present → in a compartment that drops below freezing in winter, only the second declares it.
- 12.3 kg, compact, against 44.9 kg, flat → the first fits wherever there is a free corner, the second needs a wide, low compartment.
Which one to choose
Choose ECTIVE LC 50L BT 24V if…
you have a compact 24 V system and want a 12.3 kg battery with Bluetooth control and IP65 protection. The trade-off is 50 Ah, a 50 A current limit and no declared protection against charging in the cold, which matters if the compartment drops below freezing.
Choose LiTime 48V 100Ah ComFlex 3U if…
you have a 48 V system and need a 100 Ah battery that delivers and accepts up to 100 A, with cold-charge protection. In practice you pay in space and weight: 44.9 kg in a flat 44.2 × 48 cm case, 13.3 cm high, which has to be planned into the compartment.
