Marine batteries: deep-cycle power for life on the water
Marine use is hard on batteries: vibration, moisture, long discharge runs and charging between trips. This page covers the LiFePO4 deep-cycle range for commercial boats, yachts and trolling motors, and how to choose within it.

Deep-cycle service is the defining marine requirement. A starting battery delivers a short burst and is recharged immediately; a deep-cycle marine battery delivers sustained power over hours — running a trolling motor, powering onboard systems, or carrying a vessel through a long trip — and is then recharged for the next run. LiFePO4 suits that duty because it holds voltage through discharge, tolerates many cycles and needs virtually no maintenance, as the company category page describes in general terms. Those are general chemistry characteristics, stated here as guidance, not as a promise for any single marine listing.
Voltage configurations in the marine range are 12V, 24V and 36V, and the choice follows the vessel's system: a small boat with 12V equipment, a larger boat with a 24V trolling motor, or a commercial vessel with a 36V system. The company category page lists individual marine models including 12V, 24V and higher-capacity packs, and this site does not merge their specifications: a buyer should choose the voltage first, then the capacity the trip demands, then confirm the exact model's dimensions and protection in writing.
The marine environment adds questions that a land application does not. The battery's housing and sealing, the charger's environment rating, and the wiring and connectors all face moisture and vibration, and the charger detail page on this site makes the point directly: an indoor charger is not a marine charger, and fully exposed charging needs a waterproof series. A marine inquiry should therefore state the vessel type, the system voltage, the load and its duration, and whether charging happens on board or ashore. Those four facts determine the pack and the charger together.
This page makes no claim about any vessel, fleet or marine operator. It describes a battery range and a selection method, and it points to the marine selection guide for the detailed comparison between lithium and lead-acid service in marine use, stated there in general terms.
How to choose in this family
Fix the chemistry first, then the voltage and series count, then the capacity. Check the exact model listing for its own dimensions, protection, certificate set, minimum order and lead time — those values belong to that listing and do not transfer to other models. If no listed size fits your enclosure, the custom route covers custom dimensions and configurations; describe the enclosure and the electrical requirements rather than asking for a general price.

How to place an inquiry, step by step
- Send the device facts. Tell us the device type, the available space (length, width and maximum thickness), the nominal voltage you need, the capacity or runtime you target, and the peak current if your device has motors, radios or heaters.
- Name the model or the chemistry. If a page on this site matches, quote its model description and listing details. If nothing matches, say so and describe the chemistry and voltage you need, so the conversation starts on the custom route.
- Confirm documents and terms in writing. Ask for the certificate set for that exact model, confirm the minimum order, the price basis and the lead time for that listing, and confirm payment and warranty terms before you pay. Terms stated for one model listing do not transfer to another model.
- Agree the sample step. Confirm whether the next step is a listed sample, an engineering sample for a custom design, or a small trial order, and what test you will run on arrival — fit in the enclosure, runtime, or peak-current behaviour.
Send all of this in one message through the contact page: device type, space, voltage, capacity, peak current, model description if you have one, and the documents you need. That is the whole inquiry — no separate form, no account, no extra step.
What to send us now
Send one message with your device type, the space the pack must fit, the voltage and capacity you need, the peak current if it matters, and the model description if a page on this site already matches. Add the documents you need — certificates are available upon request — and whether you need a listed model or a custom design. Use the contact page or write to [email protected], or call +86-755-25629920. A specific message like that is what turns a range of hundreds of models into a short, answerable question.
