New problem with charger ...I Think

[38super]

Hi All
This just started . I' ve been getting a (Connection Break) in the charger display in the middle of a charge. one of the batteries is a Turnigy nano 35c/60c 14.8v 4s 5000 mah battery with maybe twenty cycles.
This is happening all the time now on this battery..... seems to happen at about 15,2 v every time.

Not sure if it is the charger or the battery? First time I saw this was with a brand new Max Amp 9000xl 14.8 4s 100c battery. If it is battery I want to replace it (Max Amp)
because this is a very $$$$ battery. On the max amp and all my batteries I always charge in balance mode. Something that bothered me on max amp was on first charge.... number 1 cell was off from the other 3 cells. I remember seeing something like cell 1 ...4.0v cell 2 at 3.80.cell 3 at 3,80. cell 4 at 3.80 in the course of charging . Charger is a B6 multi charger
power supply is 350 watts. Has anyone had this happen in the middle of a charge? When I call max amp I'm going to exchange it . For such a expensive battery I don't want to take the chance of a short lived battery

I would say it it more likely that it is your cables to the charger than a bad battery. Check your balance charge leads, possible one of these is loose either or your battery or from the charger to your battery,

If you have a small Lipo alarm, connect this to your battery to check the voltage in the cells, If one cell is low then its the battery
