The 5S pack is ok I can charge it in another charger.

Its really weird I thought that maybe someone else had seen this problem...

Hi Hakan,

I use a MRC 989 for just about everything I charge. I have alot of different rechargeable things around the house too.

I made a connector harness for my charger that has just about every type of connector on it that you can imagine.

Some of the connectors, such as "M" style won't carry alot of current and sometimes don't make a good connection every time.

I get the same type of behavior when I have a bad connection. It will read the voltage, then apply the charging current. If the connection is too "Loose" to carry the charging amperage, mine behaves exactly like what you just described.

I then have to reset by powering down the power supply and start over. By establishing a better connection, it will charge.

I bet you have a weak connection somewhere. It could be where the harness plugs into the side of the charger.
