some racer said we should not run a complete pack, should stop at 5 mins.
is it true? I think the esc manufacturor should do something on it. I think it is ridiculous.......cheating the customer......
it's really strange to see what happenned to you.but in related with "lost punch" is it possible if the pack is become weaker after over 5 times cycle so you feel just lost the punch
?
