I have a max charge voltage setting on my charge controller . I have temp compensation set up at -4mv per cell as per the data sheet . Is there a max charge voltage the batteries will take when very cold ? I note the Absorption range is up to 14.6volt or 14.9 volt fast charge , should 14.9v be the highest even at low temperatures of 5 degrees and under ? or does it not matter and I should set at 15.5 v or something ?
