thanks i found a new li-poly at
http://www.b-p-p.com/kokam145.htm its a little smaller and i think this one will fit. i found out that the other one wont b/c its too big and the size of the batterie bay is the size of2 AAA side by side so i found that one thats the size of a quarter and the quarter is only a little bigger than 2 side by side AAA. so if you take those flexible sides on the batterie away it will fit. not take them away but fold them over.
