Common Sense RC Lectron Pro 6.6V 2000mAh 5C LiFe Receiver Flat Pack with Servo C

6.6V means you will not need a regulator!
This 6.6V (2-cell) 2000mAh 5C LiFe (lithium iron phosphate, LiFePO4) receiver battery supplies a fantastic mix of performance and convenience. Our LiFe batteries have some unique advantages over other battery choices that make them perfect for usage in radio systems:

Voltage stays above 5V throughout your whole run, so you get more consistent servo speed and torque than with NiMH batteries

Slightly lower voltage than Lipos means you can securely connect 6.6V (2-cell) LiFe batteries to your receiver without requiring a voltage regulator
Our 2000mAh capacity beats the 1300-1800mAh you'll find in conventional flat and hump packs from the majority of other providers
