Engineered for the Marine Environment
Conquer tight spaces on your boat with confidence. This marine-grade slimline battery is built to resist corrosion and handle the unique demands of life on the water. Its compact design maximizes space in your battery compartment while providing dependable power for your electronics and trolling motor.
Product advantages:
Marine-Grade Construction:
Corrosion-resistant materials and coating protect against salty, humid air.
Enhanced Safety Design:
Extra-sealed terminals and robust casing for maximum safety in marine applications.
Vibration Resistant:
Engineered to withstand the constant movement and shocks experienced on boats.
Space-Saving Form Factor:
Fits in narrow compartments under seats or in console boxes.
Maintenance-Free Reliability:
No ventilation required, eliminating fumes and acid leaks.
The LiFePO4 batteries VS Lead-acid batteries:
| Haicen LiFePO4 batteries | VS | Old technology-Lead-acid batteries |
| Stable discharge condition | Low temperature condition | Unstable discharge condition |
| 3,500 times | Cycle life | ＜500 times |
| Around 10 years | Design life | 3 years |
| As little as 3.5 hours | Charging time | Up to 8 hours |
| No memory, opportunity charge | Charge frequency | Must charge after use |
| Multiple built-in protections, high thermal and chemical stability | Safety | Gas inside may cause explosion |
| 85% or more nominal capacity achieved at high working load | Available capacity | Only 30%~50% nominal capacity achieved under high working load |
| Maintenance-free | Maintenance | Regular water-adding and inspection required |
| Pollution-free | Eco-friendly | Lead is a toxic substance, may cause human lead poisoning |
| Extremely low | Energy loss | 15% |
Key Points for Quality Control:
Cell match: More strict cell matching standard, the difference of lnternal resistance is 1mΩ and voltage is 5mV.
Automatic cells welding: Cells are assembled by Automatic welding equipments to ensure the quality reliability and consistency.
100% Cycle test: All battery packs are 100% cycle tested (Fully Discharged→Fully Charged→Fully Discharged→60% Charged) before package and all test reports are stored.
Unique tracking number: All battery packs are lasered an unique number on the case side for quality tracking.
