Regarding Battery Chargers - Avoiding having the negative terminal pulled below ground?
EDIT: I can no longer reproduce the potential I measured previously. I was likely mistaken.
Hey everybody,
I got a cheap battery charger off Amazon, that I found out pulls the negative terminals of the batteries below ground, instead of pushing the positive terminals above ground.
Is this standard for battery chargers?
Does anyone know of a (24V/8s, preferably >10A) LiFePO4 charger that for certain pulls positive above ground?
As a (hopefully) catch-all question: is there some other reason that my hopes and dreams of having the negative terminals of my battery at the same potential as ground/neutral while charging doomed?
The reason this is something I am trying to change is that I am running a PC off of the batteries in question, and the power supply I'm using uses the negative side of the batteries as ground. Meaning, if I plug it into, say, a monitor that's plugged into an outlet... 20V+ potential across the ground pins. Not ideal. Sub-optimal, even.
