Hi Guys
I bought this battery http://www.hobbyking.com/hobbyking/s...o4%5FPack.html. Can this be used for Rx pack? I realized when i got this that it has XT60 connectors. My screw up. But if i change the connector can i still use it for the Rx or does it have too high of a discharge rate? Any help would be appreciated.
Thanks

Loads of people, myself included, are using 2S LiFePO4 packs unregulated with great success. I currently fly with nothing else. That is in everything from gliders (6 servo thermal duration planes) to helis (including 90 sie), and airplanes (pattern). Change out the connector and charge using the A123 setting on your charger (if you have one.DO NOT charge on the lipo or NiXX settings). No worries. Just about any major brand servo rated for 6 volts can handle an unregulated 2S LiFePO4 pack.

My concern with using these as Rx batteries is the high "C" rating. These are 30 C and also that the wire from the battery is very thick (12 AGW). The leads that i have with the Futaba type connectors are very thin. Would this work connecting the thick leads to the thin ones. Would the "C" rating effect the servos or anything?

The C rating refers to how much discharge current the battery can handle. Since you have a 2100mah battery, rated at 30C, the battery can handle 60a current draw. Depending upon the number and type of servos, you will be lucky to draw 5a, so you will be well below the max that the battery can handle. The size of wire and the connector used on the power leads of the battery depends upon the amount of current being drawn. You can make up an adapter to convert the XT60 connectors to 22ga servo leads.

You have not said what type of aircraft and power system you are using this battery for. If you are using the battery just for the Rx, you can plug it into a switch harness with normal servo leads.

In the future, you might pick a battery that is specifically designated as an Rx battery. They come with servo leads already soldered to the battery. You also do not need to pay extra for such a high C rating.

Remember that the C rating is what the battery can deliver. You have an 8" water main coming down the street to your house, but when you turn on the shower you only get what you need. If all you had was a 1" pipe then if you open another source like turning on the washer, you wouldn't have enough water because that little pipe couldn't handle the demand but with that 8" main you don't have to worry, you can run the washer, water the grass, etc when the demand increases because of the capacity of the water main but it will still work just fine if all you use is the shower

An excellent and a very relevant and practical example.

Hobbyking sells the ZippyFlightmax 2500mA.hr 6.6V liFePO4 pack. I am using 3 of them.

HK also has little 700mah LIFE rx batteries. Just right for the smaller, lightweight applications....
