Default what battery for hacker 20-22L?

Whats the best battery for a Hacker 20-22L on a 14-16oz 3d foamy? I've been told the motor can pull over 20 amps, so i need a battery that can handle it. Would TP 1320 prolites be sufficient? What is an acceptable weight for a battery on this size plane. Any suggestions on what i should look for would be very helpful. Thanks.

The 1320 3 cell will work but watch your amp draw. The new 1320 can handle 17 amps cont. If your up over 20 amps I'd look at the 2100 3 cell.

true..the motor can handle the higher amps...

forgot to mention that I prop it so I do not exceed the draw of the battery.....

I have flown it with a bigger battery (my 2100) and an 11 x 7 and it was fine

Would a 10x4.7 prop prevent over amping the motor and battery? And would the 2100mah be too heavy for a 14-16oz plane?

that would be a good prop... and Yes... the 2100 would probably be too heavy..the key to foamies is to do ANYTHING possible to save weight
