SC-C48150-P lithium ion boat battery, 48V 150Ah

The highest-capacity variant and the vessels it serves

The SC-C48150-P is the highest-capacity model in the Marine Drive range. The product page states it is a 48V nominal, 150Ah LiFePO4 battery pack with 7200Wh of stored energy, and the company profile describes the marine packs as about 40% lighter than lead-acid. That matters on board: less weight in the bilge or battery bay.

The marine range's application list includes ferries and cargo ships alongside yachts and fishing boats. Which variant serves a given vessel is a sizing question: if you run a commercial passenger boat or a workboat with high hotel and propulsion loads, this is the row to cost first and confirm against your duty profile in the inquiry. The 150Ah capacity and 7200Wh are the top of the range.

Before you commit, confirm the physical fit and the duty profile against your own vessel. Ask for the test reports and certificate documents your market requires for the exact model before you order.

300A of standard discharge, explained

The standard discharge for this model is 300A. In propulsion terms, that is the continuous current the pack is rated to deliver under the supplier's standard conditions. It is the figure that tells you how much motor current the pack can support without relying on short bursts. For a bigger electric boat or a working vessel, that headroom is what lets you size the drive system around the pack rather than the other way round.

The smaller variants in the Marine Drive table carry lower standard discharge rows. That difference is the main reason to move up to the 150Ah model: not just more energy, but more continuous current for larger motors and heavier loads. The charge voltage is 54.75V, standard charge is 75A, and impedance is ≤80mΩ, so the pack is specified as a complete system element rather than a bare cell block.

Speed, range and runtime are not properties of the pack alone: they depend on your hull, motor, controller and duty profile.

Suitability, approvals and ordering

Suitability is your call, not ours. The company describes the marine packs for the applications on its list, but you must confirm the suitability and any classification or approval your application requires before ordering. That applies to ferries, work vessels and any commercial craft where a surveyor, insurer or flag state will ask questions. Ask for the test reports and certificate documents your market requires for the exact model before you order.

To get a useful quote, send the inquiry form with your application and model details. For a commercial vessel, include the motor make and model, the controller, and the duty profile: how the boat is used, how often, and for how long. Add the quantity of packs you need and the destination, because shipping and documentation depend on where the packs are going.

The more concrete your inputs, the faster the supplier can confirm whether the SC-C48150-P fits. If you are still comparing variants, say so and include the smaller rows you are considering. That way the reply can address the whole range rather than a single model.
