Ive had a set of Epic3800's go, had a bit of warning so chucked them into long grass.
What I tend to do now, is leave my cells with whatever is left from a race in then either in the morning of the night I am racing or the evening before the day I am racing I will discharge, allow to cool, equalise, cool and partial charge my IB4200's to 3000mah at home - then when I go to the track I peak the cells for racing with.
Is this a bad way of doing it?
My IB4200's seem to have deteriorated in performance faster than any other cells I have ever had.
