my unit burned out after i attached it to my 48v battery ( about 54v at the moment of connecting) and there was magic smoke coming from the L7987 buck IC.....

Hello JanosK,

if you send the board in, we may be able to repair it if it is not too badly damaged. 

Please contact our support team at service@joy-it.net and they will discuss the further details with you.

Best regards
