Considering Purchase of Amita tech battery - some questions

Hi, i would like to know if the ESD charger can be updated to work with the 7.2Kwh Amita tech pack? i presume i will need to send the charger and the MC back to you for update service so they are compatible with the can bus BMS included in the pack?

could you advise if the BMS has a contactor to disconnect the pack to protect it from discharge?

Thanks,
