75/15 connecting to dual batt in 4x4 with optional VSR capability

Hi all, just about to set up a 75/15 mppt to charge the second deep cycle battery when the 4x4 is stationary. The battery is already connected to the alternator via a VSR is there any problems leaving the mppt connected directly to the battery whilst driving and having the battery charging off the alternator? Mppt is permanently connected to a 110w panel. Battery is lead acid. Cheers everyone.

That will be fine leaving it connected to the battery while driving and the alternator is charging as well
