Bill, the OP said there is a significant spark when reconnecting the
pack to the charger, that is the reason he wants to leave the charger
connected to the pack at all times.
The proposed diode is to avoid the charger draining the pack when it
is not powered.
Best I can come up with is to keep the charger powered.
All else I can think of will require modding the charger, especially
knowing the tendency of smart chargers to want to see pack voltage
before starting a charge.
