How we assign awards →The differences that matter
- Capacity 200 Ah vs 280 Ah, both at 12 V → in theory about 2.4 kWh vs about 3.4 kWh (voltage × Ah, manufacturer-declared values): at the same load the second lasts about 1.4 times as long.
- Maximum charge current 100 A vs 200 A → in theory about 1,200 W vs about 2,400 W accepted: with a powerful charging source the first is the limit.
- Shape: 13.6 cm thick (46.6 × 32 cm face) vs 14.5 cm high (34.5 × 33 cm footprint) → the first stands in a narrow space, the second lies flat.
- Protection IP55 vs IP21, warranty 5 vs 7 years → the first tolerates a less sheltered spot, the second covers two more years.
Which one to choose
Choose ECTIVE LC 200 Slim LT 12V if…
You have a 12 V system with moderate consumption and a space that is narrow in thickness: the battery is 13.6 cm thick, and its IP55 rating also suits a less sheltered spot. You give up energy, half the charge current and two years of warranty.
Choose ECTIVE LC 280s LT Underseat if…
You want more energy and quicker charging and have room for a low, wide block, for example under a seat. The trade-off is protection: IP21 wants a dry, covered place. In return it has a 7-year warranty.
