Lithium Iron Phosphate batteries have very low self-discharge rates and stable output voltage at 12 V. LiFePO4 batteries can deliver much higher energy density in comparison to other chemistries. They are safe batteries and suitable to work in harsh ambient temperature. With the built-in BMS they are self-protected against overcharge, deep discharge and over/under temperature situation. Allows up to 2,000 discharge cycles at 80% depth of discharge. In terms of weight they are lighter than other chemistries which make them more suitable for portable applications.
