How we assign awards →The differences that matter
- Capacity, 105 Ah vs 280 Ah (manufacturer-declared values) → same voltage, so the only change is how much energy you have before recharging.
- Maximum discharge current, 105 A vs 350 A → the second sustains far more loads running together.
- Maximum charge current, 105 A vs 200 A → the second can take up to 200 A, if the charging source delivers it.
- Weight, 8.9 kg vs 28 kg → the first is moved by hand; the second is placed once and left there.
Which one to choose
Choose ECTIVE LC 105 Dual 12V if…
you want a battery that is easy to handle and fits a small space: 8.9 kg and 27.8 × 17.5 × 19 cm. The compromise is scale: 105 Ah, 105 A on discharge and a 5-year warranty against 7.
Choose ECTIVE LC 280s LT Underseat if…
you want a large reserve and high current on the same 12 V system: 3.584 kWh, 350 A on discharge and 200 A on charge. The cost is weight, 28 kg, and a 34.5 × 33 × 14.5 cm case that takes up a lot of floor area.
