Battery for CPP

[rsking45]

Hi all,
I want to get a few more batteries for my cpp,what other batteries can be used,besides stock? I would like to get longer flight times than stock.I would also like to use the balance charger that came with the cpp.I am just learning to hover so no 3d flying is going on except when its out of control :arggg:
Thanks all

electrifly packs work with the stock charger that comes with the cpp. i use a 1500ma 3s electrifly pack. its big and weighs a hair more then 2 stock 800ma 3s eflite packs. im learn the 4 ways of hovering with no 3d, unless on a sim. but the added weight helps stable it out alittle
