Multiplus charging at higher V than in settings

Hi All

My Multiplus, when charging batteries, is charging them at a higher V than in the settings.

For example - if I set the Multiplus to charge in Absorptions 14.6v and float at 13.8v - the BMV712 is showing charging about 0.2v higher - always. When in absorption it is charging at 14.8v and in float it is charging at 14.0v.

Any thoughts on why this is happening ?

Thanks

Tim

Hi @Miya,

temperature compensation could be the reason. More on that here: Multiplus Charge Voltage Temperature Correction Coefficient
