No do not go over 100 amps and a review of this battery on you tube took this battery apart and found soldered connections .
He stated he would not even pull a 100 amps because you risk melting the solder on the connectors inside the battery cells pulling over 100 amps.
He stated he would not personally pull more then 50 amps based on how the battery was out together.
I do own this battery and have pulled 80 amps off it without issue but I’m careful after watching that video.
