problems charging an LRP tx lipo

[musicman]

I am having real problems charging my LRP Tx lipo battery.

It's an LRP VTEC 3000mah 11.1v lipo that I use in a KO propo Esprit III transmitter.

The charger that I have is a Core RC UDC 30.

It has always charged fine, and I never let it drop below 11.1v on the transmitter voltage readout displayed on the screen. I have just come to charge it and it either starts and stops almost instantly, displaying a voltage of 11.38v, or the charger doesn't start and displays the message 'connection break'.

Any help would be very much appreciated

thanks
