Comments about Guest Guest Bluewater Cruising Series Battery Chargers:
The charger installed easily and is quiet. I was little disaoppointed as thought the charger had built in circuit breakers. It does not and a 15A fuse is needed on each positive leg. The description also indicates there are DC cables for auxillary use. There are not. According to the manual that came with the charger there are 4 variations of 2621A. The one here is apparently 2621A-OEM which does not have these features. All in all a good charger for the money and charges both lead and AGM batteries wihtout having to set anything.
