yeah it depends on which unit you have. If you have the one where flashing red and green means trickle charge, you're ok. If not, then likely the dc to dc power coverter has gone out, and is probably the charger is gone. Look up the post stock charger dead for more info.

Also esky makes a better charger than eflite even though it is basically the same thing. Look up esky lipo charger on ebay and there is one for $16 bucks with shipping.
