i have a mutimeter  i was trying to charge a 48v sla battery pack

i think to chager was faulty because i split the pack into two 24v pack and am able to charge with a razoz scooter charger just fine it just takes twice as long

So for the 48V DC output they are using a standard 3 pin IEC mains connector like you'd plug into a PC power supply?

 

Fairly sure that would be verging on illegal in the UK.

 

The L & N stand for live and neutral but these are AC terms. It could be wired any way really but common sense would make L positive and N negative but you need a multimeter to confirm.

 

Who's the maker and what's the model number?
