Anyone have these symptoms for these KP or any other batts

[Nazar78]

Anyone have these symptoms for these KP or any other batts? I'm on less than 10-20 cycles, no bloat, no damage, no over discharge, only warm after flight. After full charge, all 3 cells are in almost perfect balance 4.19-4.20v. Set my HW30esc to high cutoff, which is around 3.2v. Only recently I notice after frequently measuring each cell, after like more than 5mins of non-stop flight till the esc cutoff took effect, all the cells become unbalanced quite badly ie. 3.28/3.35/3.40v. Balance charge`em gets back to normal 4.19-4.20v. Is it normal for these batts to unbalance every discharge? Thanks...

bro u mean kong Power batts? if it does that.. it could be faulty cells liao..

some cells have gotten "weaker" than the others.. try to bring in for some "warranty" if u bought recently..

With 3.28/3.35/3.40 your total voltage at this stage is 10.03V.
I would not venture into that discharge state. Lipo has a steep drop towards the end of the cycle.

I usually end my flights at 11.2-11.4V. Battery lasts longer when treated gently. Plus my charging time is also reduced. I usually have 3-4 packs of the same kind to satisfy my needs.

Other than the problematic bloating of earlier DN packs (manufacturing issue) I have no problems with my batts.

Cheers,

quite agree... set a timer and minus off 1 min off ur flying time..

mine is usually ard >11.3 after 4 mins flight in idle up

ooo, i tot setting the esc cut off to high is good enuff cos i saw many said not to go below 3v per/cell. so i stay at 3.2v each. Will set the timer on my tx to 4mins, tankz broes...

hmm i think u can fly for abt 7mins if rpm not too high...

btw nowadays, i set mine to cut off at 8.5V(note below 3/cell) to prevent softcut from being triggered in mid flight during heavy punches..

timer is now my only defense against over discharging
