### ⭐⭐⭐ Not sure
*by M***S on April 28, 2023*

I plugged it into my 48v Titanit 40Ah battery bank voltage did not move it’s been plugged in for about an hour now it was getting warm to the touch when I first connected it so I rested it on top if 1 of my battery chargers that’s not plugged in because it’s got a metal case it’s now about an hour & a half it was about 12 noon and now it’s 1:28 pm I go down and see if it’s gotten smoking hot or not ! It’s slightly warmer to the touch ! Do Know if it’s doing anything or is it just paranoia buy !
