Product Description

HNF Battery 12.8V 45Ah LiFePO4 Custom Battery Pack

This 12.8V lithium iron phosphate (LiFePO4) battery pack is a custom-engineered solution built using 33140 cylindrical cells arranged in a 4S3P configuration, delivering a rated capacity of 45000mAh (45Ah) and a rated energy of approximately 576Wh. As a factory-direct manufacturer, HNF Battery designs this pack to order — configuring cell count, capacity, connector type, wire length, and BMS parameters to match your specific equipment and application requirements. This makes it a reliable, long-cycle-life alternative to lead-acid batteries for demanding 12V-class systems that need higher power output and extended runtime.

Key Features:

  • Custom OEM/ODM Configuration – Voltage, capacity, connectors, wire gauge/length, and enclosure can be tailored to your project specifications
  • Stable 12.8V Nominal Voltage – Direct drop-in replacement for many 12V lead-acid applications
  • 45Ah High Capacity – Extended runtime for high-drain and long-duration devices
  • LiFePO4 Chemistry – Superior thermal stability and safety compared to NMC/ternary lithium
  • 33140 Cylindrical Cells (4S3P) – Larger-format cells for improved power density and pack efficiency
  • Charging Limit Voltage: 14.4V – Compatible with standard LiFePO4 chargers
  • Multi-Certified for Safety & Compliance – CE, RoHS, IEC 62133-2, and UN38.3 tested, with lot-level traceability
  • Robust Configuration for Demanding Use – Suitable for RVs, portable power stations, and mobile equipment
  • Color-Coded Leads – Red (+) / Black (–) for easy, error-free installation, customizable to your connector standard
  • Compact, High-Density Form Factor – Efficient use of space for equipment integration

Applications:
RV/camper house batteries, portable power stations, electric golf carts and utility vehicles, floor cleaning equipment, small solar/off-grid energy storage, mobile medical equipment, and security/surveillance base stations requiring extended backup power.
