Last weekend the club sponcered a heli flyin and I brought my electric helis along with my Hyperion 610 I charger.
After I had exhausted my charged batts I started chargeing and discovered my batts becoming quite warm during the charge cycle which is very unusual.
I stopped chargeing and called it quits for the day, brought all the stuff home and began chargeing in my shop.
I use a 20amp switch mode pwr supply.
Now my charge cycles are back to normal with no elevated batt temps during charge cycle.
I normally charge at 2C but at the field I could only charge at 1C.
Any takers on this one..??
