Smaller size,normally 1/3 as large as conventional SLA battery;
Lighter weight,normally 1/3 as conventional SLA battery;
Longer cycle-life,SLA battery is about 300cycles while LiFePO4 battery can be 1000 cycles or more;
Good performance in deep discharge,LiFePO4 battery can be 100%DOD while SLA battery is 60%80%DOD,which means LiFePO4 battery will need less capacity in the same condition;
