Voltage measurement in such devices typically has a precision of +/- 5 %.
For 4.2 V that means +/- 0.21 V. So seeing 4.4 V on a cell is perfectly possible.

If you read the instructions on some of the battery packs, you'll find out, that most manufacturers of quality cells have warnings regarding this issue, since Kathodes of Lipo cells tend to corrode faster when applying to high voltage.

It is true that, even an entry lvl modern electronic loader will cut off a cell that's going to high in voltage, but the described problem may lead to an increased difference in internal resistance of the cells, only making the problem of an unbalanced pack even worse.

All that theory means that you have to get your packs balanced, or the problem will get worse and the method described in my first post above is a nice and easy way get things balanced again.

"Im gonna take your advice on charging it at .1C but will it be ok unattended? i dont know if i could sit there for 10 hours lol. 30 mins is one thing. by rinse do you mean run the pack in the truck? before i charge the pack at .1c should i maybe put the pack to storage mode? Once again i appreciate the input you guys do know your stuff. and if the lipo is done for ill just order some more. maybe 3 this time and hope for all good ones and side line the problem pack."

Indeed run your pack in your truck after loading it, after all you want to see if it can handle the power output you need. The desribed method for loadbalancing your packs with 0.1C is safe, even when overcharging, at least when using new generation cells, which will not explode and/or take fire with this low charging current. But in the unlikly event of overcharging 1 or more cells for a long time, they will corrode and increase their inner resistance to the point that they will be unusuable. This will only occur if at least 1 cell was in that state before you tried to load the pack, so no loss there.
