Product Description

VMAX LFP12300BH Self-Heated Lithium Bluetooth Battery

The VMAX LFP12300BH is a 12V 300Ah LiFePO4 deep-cycle Bluetooth battery in a Group 8D footprint, engineered for marine, RV, off-grid solar and energy-storage systems that demand high capacity and dependable power. Designed with an internal self-heating system for safe cold-weather charging, plus a built-in Battery Management System (BMS) for protection and long service life. Integrated Bluetooth battery monitoring and light 77 lb design makes it a perfect drop-in lithium upgrade over heavier AGM or flooded batteries. An IP67 rating, fast charging, and long cycle life round out this versatile, maintenance-free solution.

LFP12300BH Features:

  • Self-Heating – Enables safe charging below 32°F (0°C) for year-round use
  • High Capacity 300Ah – Extended run time for trolling motors, RV house loads and off-grid systems
  • Built-In BMS Protection – Over/under-voltage, over-current, short-circuit and temperature protections
  • Light Weight – Easier handling and drop-in replacement for many 8D VRLA/AGM applications
  • Fast, Efficient Charging – Optimized for LiFePO4 smart chargers and solar charge controllers
  • High Discharge Capability – Supports demanding inverters and DC loads up to 200 continuous amps
  • Scalable System Design – Wire up to 4 in series (24/36/48V) or 4 in parallel (up to 1,200Ah) for larger banks
  • 5 Year Warranty – Backed by VMAX's industry leading customer service

Why Choose the LFP12300BH?

Part of the trusted VMAX LFP series, the LFP12300BH pairs high-grade LiFePO4 cells with an advanced BMS to deliver stable, maintenance-free deep-cycle power. Its integrated self-heating system maintains charge acceptance in freezing conditions, making winter operation practical for RVs, boaters, and off-grid users. The Group 8D footprint and M8 terminals simplify drop-in lithium upgrades where AGM or flooded batteries were previously used. With fast charging, high discharge capability and support for series/parallel banks, it scales easily from a single house battery to multi-battery energy storage. Backed by a 5-year warranty and a 10-year design life for reliable power and long-term value.
