I tried a non-Elfite lipo in mine and got burned - the connector pulled off in spite of my carefully trying to get it connected to the charger - waste of money. I've had good results from the Hyperion lipos and they are all I'll use.

These have been tested on RC Groups and they perform as rated. They are 5C charge capable. Be careful with the biggers ones - even the slightest bit more weight and it'll unbalance the heli. Try a quality 120mah - theres a big diff in flight time and performance vs the elite batts.
The TP should be good as well.
