It appears to be the standard ProBoat 45 amp marine controller, the ID may be under the velcro. It is programmable, are you using LiPos or the old round cells? If the former then it
MUST be reprogrammed. The programmer (PRB3311) is mentioned in the manual below. It is discontinued but you can probably find one online if you search.
