A few points:
• your liquid lead acid batteries WILL out-gas when charged, even when properly charged, so you should vent to the outside and place them in a sealed battery container NOW!
• multi-cell filling systems are fairly easy to use, but some are not that reliable. IMHO, you would be better off hand filling each cell, which also lets you keep track of the water usage of each cell and will allow you to spot a problem (excess water usage in one or more cells) before it becomes a major problem
• If you don't have an automatic 3-stage converter/charger, your Univolt WILL kill your batteries in short order. Better to keep it off and watch the re-charge until it is full rather than rely on it. A 3-stage charging section is a must!
