In the demanding world of marine applications, the transition from traditional Lead-Acid and AGM batteries to Lithium Iron Phosphate (LiFePO4) is not just a trend—it is a technological imperative. A Marine 12V 50Ah lithium battery offers the perfect equilibrium between portability, power density, and cycle life, making it the preferred choice for trolling motors, kayak fishing, and onboard electronics.
As a leading Custom Marine 12V 50Ah Lithium Battery Supplier, we recognize that "Custom" means more than just a label. It implies a tailored Battery Management System (BMS) optimized for salt-spray resistance, vibration damping, and extreme temperature stability. In today's market, global enterprises are seeking partners who provide not only a product but a robust China-integrated supply chain that ensures compliance and local support.
Years of R&D Excellence
5 GWhAnnual Production Capacity
We utilize Tier-1 automotive-grade cells from industry giants like EVE and CATL. For marine applications, cell consistency is paramount. Our 12V 50Ah packs undergo rigorous 100% capacity matching and internal resistance testing to ensure long-term stability in high-vibration environments.
Our proprietary BMS is engineered for marine safety. It features integrated protections against overcharge, deep discharge, short circuits, and thermal runaway. More importantly, our Bluetooth-enabled BMS allows real-time monitoring of SOC (State of Charge) via mobile app, a critical feature for offshore reliability.
Humidity and salt spray are the enemies of electronics. Our marine batteries are housed in UV-stabilized, high-impact ABS cases with ultrasonic welding or gasket-sealed enclosures to meet IP67 standards, ensuring the battery survives even in the harshest saltwater spray conditions.
As a Marine 12V 50Ah Lithium Battery Factory, Lithmate New Energy Co., Ltd. provides a vertically integrated supply chain. From the procurement of raw lithium to the final assembly of the battery pack, we control every variable to optimize cost and quality.
Understanding how the 12V 50Ah battery performs in real-world environments.
For anglers using 30lb to 55lb thrust trolling motors, the 12V 50Ah lithium battery provides hours of silent propulsion while weighing 70% less than a 100Ah Lead-Acid equivalent. This weight reduction increases hull speed and fuel efficiency for boat transport.
Kayak fishing has exploded globally. The compact footprint of the 50Ah model fits perfectly into kayak battery hatches, providing a stable voltage curve that keeps fish finders and GPS units running without interference.
In larger vessels, these batteries serve as dedicated power banks for critical navigation equipment, ensuring that communication remains online even if the primary engine battery fails.
As a professional lithium battery manufacturer, our factory operates in full compliance with ISO 9001 standards, and all products meet multiple international safety certifications, including CE, UL, UN38.3, RoHS, and IEC. At Lithmate, we are committed to continuously advancing and improving lithium-ion battery pack technology.
Our factory is equipped with fully automated and semi-automated production lines, along with advanced battery testing equipment and R&D laboratories. This allows us to support the entire manufacturing process—from research and design to module assembly and final testing—with high efficiency and reliability.
While LiFePO4 is king, Sodium-Ion batteries are emerging for marine use in extreme cold climates (down to -40°C). As a forward-thinking supplier, we offer Sodium-Ion options for cold-water fishing and arctic research vessels.
The "Connected Boat" is here. Future batteries will integrate directly with NMEA 2000 marine networks, allowing captains to see battery health on their primary MFD (Multi-Function Display) screens.
LiFePO4 is inherently more eco-friendly than lead-acid. We are focusing on "Second Life" programs for battery modules, ensuring that our products have a minimal environmental footprint over their 10+ year lifespan.
Yes. Because lithium allows for 100% Depth of Discharge (DoD) without damage, while Lead-Acid should only be discharged to 50%, a 50Ah lithium battery provides nearly the same usable energy as a 100Ah Lead-Acid, with much less weight.
While some AGM chargers work, it is highly recommended to use a LiFePO4-specific charger with a CC/CV profile to ensure the BMS balances the cells correctly and maximizes lifespan.
On a standard 30lb thrust motor at medium speed (drawing approx. 15A), you can expect over 3 hours of continuous runtime. At low speeds, it can last an entire day of fishing.
Our batteries are rated for 3,000 to 5,000 cycles at 80% DoD. For most recreational users, this translates to 10+ years of reliable service.
