Query: Perfect charger

I have a Yamaha 212x with two group 24 batteries with a 1,2,both switch. I was looking for a charger that would monitor and charge each battery independently because naturally one battery on my boating trips will get drained more than another due to sitting in a cove and listening to music for periods of time. This charger fit my need perfectly. Install was a breeze. Monitoring system is great.. Very easy to see each independent battery charging state (charging, trickle).. Product is great.. Now I never have the need to worry about going on a day of boating with one or two dead batteries...
