Lithium Marine Battery

Deep-Cycle LiFePO4 Power Built for the Water

Marine power demands more than a battery that simply starts an engine. House loads, trolling motors, navigation electronics, bilge pumps, and refrigeration all draw energy for hours at a time — often in a wet, vibrating, and corrosive environment. Hysincere designs and manufactures deep-cycle lithium marine batteries around LiFePO4 chemistry, delivering stable voltage, long cycle life, and a service life that outlasts conventional lead-acid banks.

Shenzhen Hysincere Battery Co., Ltd. was founded in 2013 and operates as a China National High-Tech Enterprise, with headquarters in Shenzhen and production in Dongguan. Since then, we have focused on one thing: building battery packs and battery management systems that professionals can specify with confidence. Our portfolio covers LiFePO4, sodium-ion, and solid-state technology routes, and our engineers design the BMS in-house rather than sourcing it off the shelf.

Why LiFePO4 for Marine Deep-Cycle Applications

A boat's charging profile is unpredictable. Shore power, alternator charging, and solar input vary widely, and partial-state-of-charge operation is common. LiFePO4 cells handle this pattern well. Compared with flooded or AGM lead-acid batteries, lithium marine batteries typically deliver more usable capacity for the same footprint, hold voltage under load, and accept charge faster — which means less generator time and more time on the water.

Our marine-oriented packs are engineered with the realities of the marine environment in mind: sealed enclosures, protection against water and dust ingress, and BMS logic that manages overcharge, over-discharge, overcurrent, short circuit, and temperature conditions. For customers who need a specific form factor or communication protocol, we provide OEM and ODM customization, from cell selection and enclosure design to BMS firmware configuration.

12V and 24V Systems for Boats and Trolling Motors

Most recreational and light commercial vessels run on 12V or 24V DC systems. Our LiFePO4 packs are available in configurations suited to both, and can be connected in series or parallel where the BMS and system design allow, supporting trolling motor banks, house banks, and combined house-and-start arrangements.

A representative product is the LF12100-S-T50: a 12.8V 100Ah pack rated at 1280Wh, with an IP65 enclosure, integrated Bluetooth monitoring, and a cycle life of at least 4500 cycles. Bluetooth lets users check state of charge, voltage, and cell status from a phone — useful when batteries are installed in a compartment that is difficult to access. For builders and integrators, this kind of visibility simplifies commissioning and after-sales support.

Beyond marine, the same deep-cycle platform serves RV, golf cart, home energy storage, industrial equipment, and lead-acid replacement projects. Customers who need a different chemistry can evaluate our sodium-ion line, such as the LN12100N-BL (12V 100Ah, 1200Wh), which offers an alternative for cost-sensitive or cold-climate applications.

Compliance, Quality, and Export Support

Hysincere serves customers across Europe, the Americas, Australia, Japan, South Korea, and Southeast Asia. We operate under recognized management systems, and product compliance documentation is available for review during qualification. Certificates available upon request.

Every pack is produced in our Dongguan facility with traceable incoming materials and end-of-line testing. Because we control BMS design and pack assembly, we can respond to custom voltage, capacity, communication, and enclosure requirements without long development cycles.
