Product Description
VMAX LFP12200MH Self-Heated LiFePO4 Battery
The VMAX LFP12200MH is a 12V 200Ah LiFePO4 deep-cycle battery 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. At only 47 lbs, this Group 4D lithium battery is a light weight, drop-in upgrade over heavier AGM or flooded batteries. IP67 waterproof rating, fast charging, and long cycle life make this a user friendly and durable power solution.
LFP12200MH Features:
- Self-Heating – Enables safe charging below 32°F (0°C) for year-round use
- High Capacity 200Ah – 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 4D VRLA/AGM applications
- IP67 Waterproof Construction – Suitable for wet environments and harsh marine conditions
- Fast, Efficient Charging – Optimized for LiFePO4 smart chargers and solar charge controllers
- High Discharge Capability (Up To 200A) – Supports demanding inverters and DC loads
- Scalable Design – Wire up to 4 in series (24/36/48V) or 4 in parallel (up to 800Ah) for larger banks
- 5 Year Warranty – Backed by VMAX's industry leading customer service
Why Choose the LFP12200MH?
Part of the trusted VMAX LFP series, the LFP12200MH 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 4D footprint and M8 terminals simplify drop-in lithium upgrades where 4D 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.
