A123 2500mAh Li-Fe 3.3V

Revolution: A123 LiFePO4!
The "123" cells combine the robustness of a NiCd cell with the advantages of lithium ion technology.
Ultra fast charging of the cells with 4C! (approx. 20min!)
Reliable, robust, intrinsically safe
low weight
at least the same power during the entire charging time
high cycle stability
"123" Technology:
no thermal uncontrollability
no oxygen production
no excess lithium in the cathode
Overcharging does not lead to electroplating of lithium
low cathode voltage, less electrolyte oxidation, longer lifetime
good compatibility in case of overloading
excellent service life with strong force discharge
several thousand cycles at 1C discharge and more than 75% of their capacity after 20A discharge
