Product Description
VMAX LFP2450M 24V LiFePO4 Battery (Group 27)
The VMAX LFP2450M is a 24V 50Ah LiFePO4 deep-cycle battery built for marine, RV, and off-grid power systems that need reliable, lightweight energy storage. This Group 27 battery delivers 1,280Wh of usable energy with an advanced BMS for voltage, current, temperature, and short-circuit protection. At just 25 lbs, it’s an excellent drop-in lithium upgrade over heavier AGM or flooded batteries for 24V trolling motors and house power. An IP67 rating, fast charging, and long cycle life make it a strong fit for RV, marine, mobility, and backup power bank applications.
LFP2450M Features:
- 50Ah / 1,280Wh Capacity – Delivers extended run time for trolling motors, RV house loads and off-grid systems
- Advanced LiFePO4 Chemistry – Safe, stable cells with high cycle life for deep-cycle use
- Built-In BMS Protection – Over/under-voltage, over-current, short-circuit and temperature protections
- Light Weight Design – Easier handling and replacement for many Group 27 VRLA/AGM applications
- Fast, Efficient Charging – Optimized for LiFePO4 smart chargers and solar charge controllers
- IP67 Waterproof Construction – Suitable for wet environments and harsh marine conditions

Why Choose the LFP2450M?
Part of the trusted VMAX LFP Marine series, the LFP2450M 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 27 footprint and M8 terminals simplify drop-in lithium upgrades where AGM or flooded batteries were previously used, while IP67 construction helps it thrive in wet, corrosive marine environments. 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.
