Hi @sjackson78, BMS is our Battery Management System, which is a type of software and cannot be replaced. Would you like to upgrade to the latest BMS firmware?

Or have you disassembled the EB3A and want to replace its components? We’re sorry, but we do not support such services. We would like to know what issues your EB3A is experiencing. Could you please take photos and send them to us for further analysis?
