ECTIVE LC 320s LT Underseat vs LiTime 12V 100Ah OBM Bluetooth
Technical comparison · Lithium batteries for campers
Two 12 V batteries that fit a similar space but hold very different amounts of energy: the ECTIVE has more than three times as much and weighs three times as much. The choice is between energy and lightness, and the protection rating says where each can go.

The differences that matter
- Capacity 320 Ah vs 100 Ah, both at 12 V → 4.1 kWh declared by the manufacturer vs about 1.3 kWh in theory: more than three times the energy at the same load.
- Weight 32 kg vs 10.2 kg in a similar footprint → the first is more than three times heavier to lift and to support.
- Protection rating IP21 vs IP65 → a dry, covered spot against an exposed one.
- Warranty 7 vs 5 years, declared cycles 6,800 vs 4,000 → the warranty expires first on both, at about 2,555 and 1,825 cycles at one cycle a day: the extra cycles only count beyond it.
Which one to choose
Choose ECTIVE LC 320s LT Underseat if…
You want a long stretch on 12 V and the battery goes under cover, for example under a seat: it takes little more room than the other but holds far more energy, and it has a 7-year warranty. The trade-off is weight, 32 kg, and an IP21 rating, which wants a dry, sheltered spot.
Choose LiTime 12V 100Ah OBM Bluetooth if…
You have a 12 V system with modest consumption and want a battery you can carry by hand (10.2 kg) and that can sit in an exposed spot, at IP65. You give up most of the energy, half the maximum current and two years of warranty.
