What should a 48v battery read on a multimeter when fully charged?

Hi all recieved a upp. 48v 13ah battery from germany today, i need to charge it ,not sure what the procedure is with a new battery?

 

and what the mmeter should read when fully. Charged

 

its a bit bigger and heaver in the flesh ,hailong case, Not sure it will fit,

 

thank you

Before you charge it make sure it fits. It should be at around 47-48v out the box and fully charged 54.6v. No need to treat a new battery any differently to your used ones. Charge till light on charger goes green, ride and enjoy.
