ECTIVE LC 300L LT 12V vs ECTIVE LC 320s LT Underseat

The differences that matter
- IP65 vs IP21 → the 300L LT tolerates a spot exposed to dust and splashes; the 320s LT has to be kept dry.
- 52 × 26.8 × 22.8 cm and 37.5 kg vs 35.5 × 22.4 × 19 cm and 32 kg → the 320s LT fits where the 300L LT will not, and is easier to lift.
- Maximum charge current 150 A vs 200 A → the 320s LT accepts a more powerful charging source.
- Warranty 5 vs 7 years (manufacturer-declared values) → two more years of cover on the 320s LT.
Which one to choose
Choose ECTIVE LC 300L LT 12V if…
the installation spot is not fully sheltered and you need IP65 protection. The trade-off: 37.5 kg and a 52 × 26.8 × 22.8 cm body to fit into the compartment, a 150 A maximum charge current and a 5-year warranty instead of 7.
Choose ECTIVE LC 320s LT Underseat if…
the battery has to fit a tight space, such as under a seat, and your charging source can deliver up to 200 A. It is 32 kg in 35.5 × 22.4 × 19 cm, with 320 Ah and a 7-year warranty. The trade-off is IP21 protection: it needs a dry location.
