I see. So are you charging a battery bank for an RV or an off-grid solar system? How many volts?

Why would you make that assumption ????tsellers said:
That would depend on the battery/ebike in question but the voltages are nominal 36, 48 and 52.
The latter being why I required at least a 60 Volt Power Supply.
oops ... I forgot 12 volts for for the computer UPS.

I guess I just made an incorrect assumption based on my own use. I am thinking to use a LiFePO4 for a house battery in my van, and for my 36, 48 and 52V bike batteries I currently just have Li-Ion configurations made from 21700 or 18650 cells.
As I have 2 48V chargers at hand, I have one set to a cutoff of 4.1V, and the other at 4.2, the latter is used perhaps one of 10 cycles.
