The entry-capacity variant and where it serves
The SC-C4850-P is the lowest-capacity model in the Cellforge marine drive series: 48V nominal, 50Ah, 2400Wh, LiFePO4. It is the entry point of the series, for boats whose energy need sits at the smaller end. If your vessel's loads are modest, starting with the lowest capacity is often the practical choice rather than paying for stored energy you will not use. Ask for this model's dimensions in your inquiry before you plan the installation space.
The product page states a charge voltage of 54.75V and a standard charge current of 25A, with impedance of ≤80mΩ. Those are the figures to check against your charger and your installation before you commit to a model. The company states the marine packs are about 40% lighter than lead-acid, which matters when you are lifting a pack into a small boat or trimming weight near the stern.
Small boats rarely need the largest pack in the range. They need a pack that fits, charges from the equipment you already have, and matches the motor you plan to run. Ask for the test reports and certificate documents your market requires for the exact model before you order, and confirm the suitability and any classification or approval your application requires.
What 100A at 2C means on the water
The product page states a standard discharge of 100A, described as 2C for this 50Ah pack. In plain terms, the pack is rated to deliver twice its capacity in amps as a standard discharge figure. For any installation, that is the number to hold against your motor and controller: check the current your drive pulls at the loads you actually plan to run, and treat 100A as the reference point the supplier gives for this model.
Manoeuvring is where current demand tends to spike. Coming alongside, turning in a tight channel or pushing off a dock can draw short bursts well above steady cruising current. That is why the discharge figure deserves a careful look rather than a glance: compare it with the controller's current limit and the motor's rated draw, and leave yourself a sensible margin for the bursts you expect on your water.
The 100A figure is a current rating, not a speed or range figure. Range depends on your hull, displacement, propeller, speed and conditions. The honest approach is to size the pack against your measured or documented current draw, then confirm the suitability and any classification or approval your application requires before ordering. Ask for the test reports and certificate documents your market requires for the exact model.
Suitability, approvals and ordering
Before you order, confirm the suitability and any classification or approval your application requires. That applies to every marine installation: the model choice is only half the question. The other half is whether this model suits your boat, your motor and the rules your water and your insurer work to. The supplier describes the SC-C4850-P as part of its marine drive series, but the decision on suitability rests with you and your technical advisers.
When you send the inquiry form, give us four things: the motor, the controller, the quantity and the destination. With the motor and controller, we can talk about the 100A standard discharge (2C) and the 25A standard charge against your actual drive. Quantity tells us whether you are fitting one boat or outfitting a small fleet. Destination tells us which documents you will likely be asked for, so you can ask for the test reports and certificate documents your market requires for the exact model before you order.
Keep the ordering conversation concrete. State the model you are considering, the application it goes into, and any classification or approval your application requires. That way the answers you get back are about your installation, not a generic pack.

Before you order
What are the key electrical figures for the SC-C4850-P?
The product page states 48V nominal, 50Ah, 2400Wh, a charge voltage of 54.75V, a standard charge of 25A, a standard discharge of 100A (2C) and impedance of ≤80mΩ. The chemistry is LiFePO4. Check each figure against your charger, motor and controller before you order.
Is this pack lighter than a lead-acid battery of similar role?
The company states the marine packs are about 40% lighter than lead-acid. That is the supplier's claim for the marine range; ask for the details behind it for the exact model if weight is critical to your installation.
What discharge current can I plan around?
The product page states a standard discharge of 100A, described as 2C for this 50Ah pack. Compare that with the current your motor and controller draw, including manoeuvring bursts, and confirm suitability for your application before ordering.
What should I send with my inquiry?
Send the motor, the controller, the quantity and the destination. Also state any classification or approval your application requires, and ask for the test reports and certificate documents your market requires for the exact model before you order.
