VMAX LFP24-1265 LiFePO4 Li-Iron 12V 65AH High Performance Lithium Battery
The VMAX LFP22-1255 is a 65Ah deep cycle battery with a 10-year design life. The 12V nominal voltage and the enhanced lead calcium phosphate batteries (LFP) designed for deep cycling make it perfect for solar power systems and many off-grid applications, including caravans, motorhomes, boats and RV's. This battery is made from premium cells, including a LFP dedicated single cell and high performance components make it well suited for many backup applications.
The VMAX LFP battery modules have a wide operating temperature range from -30°C to 50°C, and have been designed specifically for ultra-wide temperature high performance battery applications. The module can be discharged much lower than traditional SLI batteries with longer cycles time (80-100% DOD). They also offer fast recharge times due to their very low internal resistance. The innovative design of the BMS provides a lifetime warranty on the overall battery pack which includes system diagnosis and failure notification along with other
