According to Sunsynk's BYD web page, the max charge/discharge is 100A. So don't only go on what you see on 3rd party web sites. Maybe the specs shown on other web sites are still the old specs? But no, other than the official web page I have no detailed knowledge about these batteries. I would like to know more about them myself though.
Edit: I've now noticed that the BYD version has extra lights top left which the old model doesn't have?
