Yes , you can charge the pack while it's in the radio.
No, you can't discharge the pack while it's in the radio. You have to remove it.
Thats not correct.
Peak detection chargers like the accucyle need feedback from the battery to peak charge, so if the battery will charge in the transmitter it will usually discharge. Wall warts only charge and don't take voltage information from the battery so they work regardless of short protection.
