The differences that matter
- 120 Ah vs 200 Ah → at the same 12 V the second holds far more energy in a single battery
- 10.2 kg vs 25.8 kg → one person can move the first; the second needs a 39 × 23.2 × 25.8 cm space
- 5 years vs 10 years of warranty → on both, the warranty ends before the declared cycles do, so it sets how long you plan to keep it
- 120 A vs 150 A discharge → the second leaves more headroom when several loads run together
Which one to choose
Choose ECTIVE LC 120 Dual 12V if…
the battery compartment is tight and you want to fit or replace the battery on your own. You do weekends and short trips with few loads running. The trade-off is a smaller reserve and a warranty that ends at half the time of the other.
Choose Liontron LX Smart 12,8 V 200 Ah Arctic Marine if…
you stay aboard several days in a row without a hook-up and prefer one large battery. You have room in the compartment and someone to help lift it. The trade-off is exactly that: size and weight, in return for a warranty twice as long.
