The differences that matter
- Capacity 150 vs 320 Ah → the second keeps the same system running for more than twice as long.
- Maximum charge 100 vs 200 A → the second accepts far more current from chargers and recharges in less time.
- Weight 15.5 vs 32 kg → the first can be fitted and moved by one person.
- Ingress protection IP65 vs IP21 → the first can sit in a compartment exposed to damp, the second cannot.
Which one to choose
Choose ECTIVE LC 150 LT 12V if…
you use the camper at weekends and the battery sits in an exposed compartment: 15.5 kg, IP65, a 5-year warranty and 4,000 declared cycles. You accept 150 Ah of capacity, a 100 A maximum charge current and a 150 A maximum discharge current.
Choose ECTIVE LC 320s LT Underseat if…
you take long trips and want 320 Ah, with charge and discharge up to 200 A, a 7-year warranty and 6,800 declared cycles. The price is 32 kg and an IP21 rating, which needs a dry housing such as the one under the seat.
