Is the battery a 48V or 52V. If 48V I wonder why it's getting overcharged?
This is a custom profile to get 80% charge on the 52v 19.2aH battery. The Satiator closest preset is 85% I think 56.6v.
There are always small errors as we add more components to measure something.
That makes sense though I wonder if they could've compensated for that somehow with some programming.
