This 6.6V (2-cell) 32000mAh 5C LiFe (lithium iron phosphate, LiFePO4) receiver battery provides a great combination of performance and convenience. Our LiFe batteries have some unique advantages over other battery options that make them ideal for use in radio systems:
Voltage stays above 5V throughout your entire run, so you get more consistent servo speed and torque than with NiMh batteries
Slightly lower voltage than LiPos means you can safely connect 6.6V (2-cell) LiFe batteries to your receiver without needing a voltage regulator
3200mAh capacity is ideal for larger aircraft and vehicles with multiple power-hungry servos
Separate EC3 connector and 14 awg leads for heavy duty applications
