Deep Cycle Battery Solutions
Haicen Power Group 31 LiFePO4 battery is engineered for RV owners and marine enthusiasts who demand reliable starting power and deep-cycle performance in a compact form factor. This drop-in replacement battery deliver more usable energy, a longer lifespan, and zero maintenance compared to traditional lead-acid batteries.
Ideal For,
● Class B and C RVs - Powering lighting, water pumps, and appliances.
● Small to Medium-Sized Boats - Reliable starting and trolling motor power
● Off-Grid Power Carts - For solar setups and mobile power needs
● Mobility Scooters - Long-running and dependable energy.
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.
Certifications:

Key Benefits of Haicen lithium battery:
Higher qualified cylindrical cell:
UL1642, IEC62619, IEC62133 listed with Cycle life more than 3000times and excellent consistency.
Bluetooth:
enable to monitor the battery status(charge, discharge, current, temperature, cycle life and so on) and change the data for different applications.
Heating function system:
Uniform internal heating is an important feature of our cold-weather performance batteries, as many external heating blanket options currently available cannot sense the internal temperature of the cells and may not be completely effective at heating the battery throughout. The system features proprietary technology that draws power from the charger itself, requiring no additional components. The entire process of heating and charging is completely seamless. Simply plug the battery into the regular lithium charger and the internal heating and monitoring system takes care of the rest.
More stable and firm internal structure:
Cell holders can well protect and separate the cells to avoid any circuit short risk caused by vibration or impact or over current, and improve the heat dissipation.
Smaller size and less weight:
The size of our battery is just 3/4 size of the standard 12V 150Ah battery from other suppliers.
