I understand an ESC must be able to handle full amperage of the motor, and that you can't use an ESC that is half size and just run it at half throttle. Is the nature of Lipo batteries such that one can size the battery for half throttle? Is average amperage OK or must Battery size also be able to handle full amperage? Got a plane I'd like to run at much less than full throttle and would like to use a smaller lighter Lipo but don't understand if the nature of Lipo's allows this?

The problem with useing a battery that is too small is that if the battery is not able to supply the motor with the power it needs is that the voltage will likely sagg and the LVC circuit in the ESC will kick in and the motor will stop. This will likely happen when you need the power to get out of trouble and you could loose your plane also, is it worth it? Also if you try to overload a Lipo it will soon heat up and puff and be ruined. Best get the right battery for the job!!!!!!!

One possible way to use your small battery might be to prop down the motor so it wont draw as many amps to harm the battery. You will need a wattmeter for this and also know how many amps the battery can supply and then start from there.......
