I don't have technical details on the charger but I do know it can shell out about 48KW if that helps. It's definitely a DC Fast charger. I used it and didn't have problems and I did notice in the cold it was seemingly only injecting about 25KW max even at a low state of charge so perhaps...
Does anyone see any issues with using a L3 charger in extreme cold or very cold weather? By that I mean -5F - 20F approx temps? Worried the temp variations could possibly damage the battery.
