ECTIVE LC 100L LT 12V vs ECTIVE LC 320s LT Underseat
Technical comparison · Lithium batteries for campers
Two 12 V LFP batteries for motorhomes that answer different questions: a small, protected battery, or a large one that needs a sheltered spot. The 320s has more than three times the capacity (320 Ah against 100 Ah), while the 100L is the one with IP65 protection. Manufacturer-declared figures.

The differences that matter
- 320 Ah vs 100 Ah → more than three times the reserve: it sets how many days you go without recharging.
- 200 A vs 100 A charge and discharge → the 320s takes a charger twice as strong and carries larger loads.
- IP21 vs IP65 → the 320s needs shelter, the 100L tolerates an exposed spot.
- 32 kg vs 12.5 kg → the larger unit must be fixed down carefully and counts against payload.
Which one to choose
Choose ECTIVE LC 100L LT 12V if…
you have a light system in a van and want a 12.5 kg battery that can sit where spray reaches (IP65). The trade-off: 100 Ah and a maximum current of 100 A, charging and discharging, with a 5-year warranty.
Choose ECTIVE LC 320s LT Underseat if…
you need to run a large onboard system for several days, with a declared 4.096 kWh, and want a 7-year warranty. Charging goes up to 200 A. The trade-off: 32 kg to fix down in a dry compartment (under a seat, say), because the declared protection is IP21.
