ECTIVE LC 320s LT Underseat vs ECTIVE LC 80 LT 12V
Technical comparison · Lithium batteries for campers
Two 12 V LFP lithium batteries for campers of very different size: 320 Ah against 80 Ah. The choice comes down to how much energy the vehicle needs and the compartment it has to fit (manufacturer-declared values).

The differences that matter
- Charge current 200 A against 40 A → the larger battery takes everything a strong source can deliver; the 80 Ah unit stops at 40 A, so a more powerful source does not speed up charging.
- IP21 against IP65 → the first needs a spot sheltered from water, the second tolerates a more exposed installation.
- Warranty 7 years against 5, declared cycles 6800 against 4000 → on both the warranty runs out first, so the lifespan to count on is seven years against five, not the cycle count.
Which one to choose
Choose ECTIVE LC 320s LT Underseat if…
the on-board system needs a large reserve, 4.096 kWh, and loads that draw up to 200 A on discharge. The trade-off: it weighs 32 kg, the compartment has to take 35.5 × 22.4 × 19 cm, and its ingress protection is lower than the other's, so it belongs somewhere sheltered from water.
Choose ECTIVE LC 80 LT 12V if…
you want a small, light battery, 10.2 kg in 27.8 × 17.5 × 19 cm, that fits a tight compartment and tolerates a more exposed mounting spot thanks to its higher ingress protection. The trade-off: 80 Ah of capacity and a discharge limit of 100 A, which means a smaller reserve and less current on tap.
