Product Description
VMAX Heated LiFePO4 Battery with Bluetooth
The VMAX LFP12300BH is a 12V 300Ah lithium deep cycle battery that's engineered for marine, RV, off-grid solar, and energy-storage systems that require 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 a light 77 pound design makes it a perfect drop-in lithium upgrade over heavier AGM or flooded Group 8D batteries. Self-heating, Bluetooth monitoring, fast charging, and long cycle life make this a user friendly and versatile lithium upgrade.
