Performance advantages of LiFePO4 batteries
High power density, 110-135 Wh/kg
Long life, retains 80% capacity after 2000 charge cycles
Safety: Some lithium batteries tend to explode or catch fire if damaged but LiFePO4 batteries do not even under harsh conditions
Low temperature sensitivity: 105% of capacity is available at 130°F (55°C), 80% of capacity is available at -5°F (-15°C)
Low self discharge current: less than 5% per month
Very high charge/discharge efficiency, near 100% even if discharged at 5C
