Case Study For TYCORUN Boat Batteries
Freshwater Tour Boat – Lake Constance, Germany
Installation: IP65 5,000Wh LiFePO4 battery installed in an enclosed cabin.
Performance after 24 months of daily operation:
- Capacity retention: 91.2% (BMS-monitored data)
- No major hardware failures reported
- Low-temperature protection triggered during early winter mornings (resolved via standard procedure)
Operational benefits:
- Annual energy cost reduction: 28% compared to previous lead-acid setup
- Eliminated seasonal lead-acid replacements
Installation recommendation: For enclosed freshwater cabins, IP65 with ABS casing offers lightweight, splash-resistant, cost-effective performance.
Coastal Fishing Fleet – Surat Thani, Thailand
Installation: 51.2V 400Ah IP67 batteries powering primary propulsion systems.
Performance highlights:
- 400A continuous discharge under high load (fishing operations)
- Maintenance cost reduction: 24% year-over-year
- Vessel uptime increase: 15% (less time spent on charging or battery swaps)
Engineering recommendation: For high-humidity, coastal environments with potential seawater exposure, upgrade to IP67 aluminum alloy casing – salt-spray tested and proven for marine durability.

Frequently Asked Questions
What is the difference between IP65 and IP67 for marine batteries?
IP65 is protected against water jets from any direction – ideal for freshwater lakes, rivers, and enclosed compartments. IP67 withstands temporary immersion up to 1 meter for 30 minutes – required for offshore, saltwater, and open-deck installations where wave spla
sh or occasional submersion occurs. TYCORUN offers both, plus IP68 for extreme conditions.
Do I need IP67 for freshwater use?
Not necessarily. For freshwater lakes, rivers, and enclosed cabins, our IP65 ABS series provides reliable splash protection and lighter weight at a lower cost. Upgrade to IP67 only if you operate in saltwater, rough water, or open decks with direct wave exposure.
What is the real-world cycle life of TYCORUN marine batteries?
Our LiFePO4 batteries deliver 4,000+ cycles at 100% depth of discharge under standard lab conditions (0.2C charge/discharge, 25°C). Actual lifespan depends on operating temperature, discharge rate, and maintenance practices. Many users operating at shallower depths of discharge can expect extended cycle life.
Can you customize batteries for my specific boat model?
Absolutely. As an OEM manufacturer with 17+ years of experience, we offer full customization of voltage, capacity, IP rating, casing material, BMS parameters, and connectors. Send us your specifications for a tailored quote – sample orders are welcome.
How do TYCORUN batteries perform in saltwater environments?
For saltwater, we recommend our IP67 aluminum-cased series (e.g., 51.2V 400Ah model). The aluminum housing resists corrosion, and the IP67 rating protects against seawater immersion and salt spray. Our batteries are designed for marine-grade durability.
What certifications do your marine batteries have?
TYCORUN marine batteries are UN38.3 (safe transport), ISO9001:2015, CE, and TUV certified. UL compliance available on request. For specific regional approvals (e.g., CCS for China), we can work with clients to meet requirements.
Do you offer OEM/white-label services for boat builders?
Yes. We provide both OEM (manufacturing to your specs) and ODM (complete custom design including BMS programming, casing, and connectors). We serve boat builders, distributors, and fleet operators worldwide. Flexible MOQ and fast lead times.
