ESPSS Charger Security Relay Update

Last night I wired another relay for the charger line, that will be activated by switching to Charger Mode (C), and deactivated if the charger does not stop like it should in case it fails (rare but I heard it could happen)  and the pack voltage goes higher than 29,2V (8 cells x 3,65V). Also the Ampmeter will now be used to monitor the Amps going from the charger to the battery pack.
