What I'd prefer, is not really a basic charger but a low power one.
Ok, here is my list:
- 1500-2000W 110-220V dual voltage or selectable
- 2 charge profile lead and LiFe
- output voltage adjustable in 20% range, like between 120-156V
- optional PFC
- PCB with pre-programmed controller chip(from You) + BOM (Mouser?) purchase option
less important, but useful option would be a built in RTC for timed charging.
I think this is my sort list.
Thanks for reading.
