lithium polymer question
I have a skylark micro helicopter with a stock 8.4 volt 750 mah NiMH battery pack. I am looking to buy a lithium polymer battery pack but I don't know which to get. Should I get the 1200 mah or the 1020 mah? Two cells or three (7.2v or 10.8v)? I have read many posts on this and I am still not sure. Thanks
