Would it make a difference if the gender of the plug was reversed? A female lead into the charger and a female socket on the battery.
Something I have been saying for a long time. a circuit breaker or residual currant device.Yes that would probably work. There's still a risk of shorting the charger output even with the shrouded IEC connectors, however, you would hope that modern controllers have some sort of short circuit protection built in.....
