Dear Customer: Hello. The electric bike you purchased is H7UL. H7UL is the bike model. AMAK00017 is our frame number and product SKU code, and the string of digital codes on the head tube is our production batch number, also called the serial number. The controller of the H7UL electric bike is integrated in the battery base, and the integrated controller is integrated with the DP-5C battery base. If you need to replace the battery with a larger capacity, just choose the battery with the "48V DP-5C 4-pin" battery base, which is also sold on our website and you can also buy it on Amazon.
