I was lucky to get 2 of these for about $50 AUD. These were sourced from telcom techs who had to replace them due to old age. Later, I developed a small program to alter the output V and A to suit my needs. I use one now to charge the 400 AH 48V SLA battery I have for the house. The other is a spare, used for mppt testing.
