Pros
- Exceptional safety with LiFePO4 chemistry
- Excellent long-term value for money
- Very long lifespan (>4000 cycles)

The Polaris Advantage: Why LiFePO4 is Superior
The Modern, Safer Choice for Your Home
Both Polaris batteries are built with Lithium Iron Phosphate (LiFePO4), a technology that represents a major leap forward from traditional lead-acid batteries. This is the safest, most stable lithium chemistry available, as it is not prone to thermal runaway (overheating). It provides complete peace of mind for your family and property.
Furthermore, LiFePO4 allows for a much deeper discharge, meaning you can use more of the battery's stored energy in each cycle. This makes it a significantly safer, more efficient, and longer-lasting choice for your home.
