I bought a blade cx that was said to have a bad 4-in-1 but that everything else was ok, I figured i replace the 4-1n-1 done, well now I have a problem of charging the battery, When I plug the battery into the lipo/balancer that came with it all it does is blink red which indicates that its getting power to it but there is no battery there....

I talked to e flite and they said it sounds like the balancer/charger is bad, I talked to the hobby shop they said the battery is bad?.... I was told that even if the battery was bad I should still get a charge light when something was connected, and then I was told if the battery is bad the charger is not gong to register its there...

can someone please help me eleviate my confusion... is the charger bad/ or battery bad? or both????... I dont have any other way of testing or hooking up other batteries to test it
