hey guys i have got a starter box that says is has to run 2 - 7.2v lipos.

I am completely new to lipos and dont know what all the numbers mean and which ones I can use in my starter box.

Can anyone help please????

you should run 2 7.2v nimh or nicd.
or 1 14.8v lipo

Well.. For Example 5000mAh 2s 25c Ofcourse you know what "mAh" is, 2s,
3s, 4s etc is 2s 2 cell pack(7.4v), 3s 3 cell pack (11.1v), 4s, 4 cell (14.4v) and so on The "C" rating is the discarge rate. c rating divided my mAh rating gives you cont. discharge rate. 5000mAh 20c pack is 100 amps continous discharge.
I hope this helps

Something like this is usually used for a starter box -

The 2 2S lipos usually wind up in series and the 4S provides the same voltage in one package. You'll prob want to get a low voltage alarm that plugs into the balance plug to protect against over discharging the lipo.
