How we assign awards →No awards in this tier.
The differences that matter
- Capacity, 280 Ah vs 100 Ah → the 280s holds almost three times the reserve.
- Current, 350 A discharge and 200 A charge vs 100 A and 100 A → the LiTime has to stay under 100 A in both directions, while the 280s handles far higher peak loads.
- Shape, 34.5 × 33 × 14.5 cm vs 50 × 6.2 × 28 cm → the 280s is a block, the LiTime a slab that fits where there is little depth.
- Protection, IP21 vs IP65 → the LiTime tolerates a less sheltered compartment.
Which one to choose
Choose ECTIVE LC 280s LT Underseat if…
the loads are heavy and you need both reserve and peak power, with seven years of warranty. You accept a heavy block and IP21, the lower rating of the two, so a sheltered compartment.
Choose LiTime 12V 100Ah Ultra Slim Heated if…
the space is flat and weight matters: the LiTime weighs little more than half as much and is IP65. You accept a much smaller reserve and current, and five years of warranty.
