The differences that matter

  • Capacity, 120 vs 200 Ah → at 12 V about 1.4 vs 2.4 kWh nominal (the Marine declares 2.56): the second runs the same loads about two-thirds longer.
  • Charge current, 100 vs 200 A → with a powerful charger the Slim is the limit, capped at 100 A.
  • Discharge current, 250 vs 200 A → at 12 V about 3 vs 2.4 kW (current × nominal voltage): the Slim accepts a larger load.
  • Protection, IP55 vs IP67 → the Marine is the one to pick if the compartment can get wet.
