2) LiFes are safer than Lipos (do not combust easily like lipos)
3) LiFe Batteries supply a constant voltage (They stay right near 6volts from start to finish ensuring consistent flights)
4) Run Life batteries to your servos and ignition without regulators (For extra caution some people run a regulator to their ignition still)
5)Life's have a high Charging Capacity. Charge up to 5amps, allowing you to charge them up in MINUTES!
