1- What is the exact charge voltage temperature correction coefficient programed into a Multiplus (as default)?

I can't seem to find this documented anywhere, apart from the graph in the appendix pages at the back of the manual. Based on this graph I have roughly calculated it but would like to confirm 100% - as the graph may only be pictorial.

2- Is there any way to update the Multiplus charge voltage temperature correction coefficient?

I have had another look in VE Configure today but couldn't find a setting to configure it.

Thanks in advance, Mark.
