The differences that matter
Manufacturer-declared values. - 350 A vs 200 A discharge → the 280s feeds higher loads. - Height 14.5 cm vs 22.8 cm → the 280s fits under a seat, the 300L needs a taller compartment. - IP21 vs IP65 → the 300L can go where water may reach it, the 280s cannot. - Warranty 7 years vs 5 → two more years of cover on the 280s.
Which one to choose
Choose ECTIVE LC 280s LT Underseat if…
You mount the battery under a seat: it is 14.5 cm high, 34.5 × 33 cm in plan, and weighs 28 kg. Your loads reach 350 A on discharge and 200 A on charge, and you want a 7-year warranty. You accept 280 Ah instead of 300 and an IP21 rating, so a compartment that stays clear of water.
Choose ECTIVE LC 300L LT 12V if…
The compartment is exposed to damp or spray and you need IP65. You get 300 Ah and 4000 declared cycles. In return it weighs 37.5 kg and measures 52 × 26.8 × 22.8 cm, discharge stops at 200 A, charge at 150 A, and the warranty is 5 years.
