One platform, three capacities
Cellforge builds this marine range on one 48V platform, so you choose the capacity that fits your energy need rather than reworking the installation around a different electrical table. The series page sets out the 48V table behind the range, and the three variants are the three capacities on that table. That means a lower-capacity pack for a smaller energy need and a higher-capacity one for more stored energy, on the same electrical table.
On weight, the company states its marine packs are about 40% lighter than lead-acid, which matters when you are planning where packs sit and how the vessel is loaded. Size your pack from the energy the vessel actually uses, then confirm the model and its details against the series page before you order.
Vessels this range is listed for
The company lists this range for yachts, fishing boats, sailboats, ferries, cargo ships and offshore vessels. Those are different working profiles, and the pack role differs with them. A propulsion pack feeds the drive and has to deliver for the duty cycle of the boat; a house-power pack runs onboard loads and is sized around how much energy you draw between charges. Tell the supplier which role you are buying for so the pack is matched to the application, not just the capacity.
Before ordering, confirm that the pack suits your vessel and application and that you hold any classification or approval your market, insurer or operator requires for the installation.
Waterproofing and installation options
For wet or exposed installations, the company lists an IP65 waterproofing option for custom builds. Treat it as a customisation to agree for your build rather than a promise that applies to every model: confirm the exact option and what it covers for the model you are quoting before you order.
Communications interfaces are also listed among the installation-relevant options, so plan monitoring connections with your installer at the quotation stage. Ask the supplier to confirm which options apply to the model you are considering and to put them in writing on the quotation, along with the details of the pack itself. That keeps the build you receive aligned with the installation you have designed.
