I BOUGHT A ELITE ULTIMATE AND A 4100 MOTOR. BOUGHT THE WHOLE WORKS FOR MYSELF. A KID THAT RACES PYLON WITH US BOUGHT THE SAME THING EXCEPT THAT HE BOUGHT A 5100 MOTOR I THINK. ANYWAYS, HE ASKED TO BORROW MY NEW BATTERY, LITHIUM POLYMER AND CHARGED IT WITH MY ASTROFLIGHT LITHIUM CHARGER. HE FLEW IT AROUND AND THEN AFTERWARDS, CHARGED IT AGAIN. I WAS NOT PAYING ATTENTION AS TO WHAT WAS GOING ON. ABOUT 3/4 THROUGH THE DAY, HE COMES UP TO ME AND SAYS THAT MY CELLS ON MY BATTERIES HAVE EXPANDED TO TWICE THE SIZE. WHAT SHOULD HE DO. WELL I TOLD HIM TO LET IT SIT FOR A LITTLE BIT AND WELL FIGURE IT OUT ( OUT IN THE DIRT OF COURSE AWAY FROM EVERYTHING ) . wE COVERED THE BATTERY SO THE SUN DID NOT BEAT ON IT. ABOUT A HOUR LATER ALL THE CELLS HAD EXPANDED.

MY QUESTIONS IS, IS THIS NORMAL FOR THIS TO HAPPEN, HAS ANYONE HAD THIS HAPPEN AND WHY DOES IT HAPPEN. I AM NOT SURE THE CIRCUMSTANCES OTHER THAN I BOUGHT A NEW BATTERY 1320MAH AND NOW IT IS NO GOOD. SO I AM OUT $70.00 NOW.

I KNOW HE WAS CHARGING AFTERWARDS AT 1.3AMPS . COULD THIS BE THE WHOLE ISSUE. I KNOW HE HAD ABOUT 3-4 FLIGHTS THAT DAY.

ANY HELP WOULD BE APPRECIATED.
