I'm looking at the Flow-Rite Pro-Fill battery watering system for my Allegro. From what I have seen they seem to work well. Does anyone have thoughts on these?
I have one in a 4 battery system where the back two batteries are very hard to get to. The front batteries are okay to service. I put the Pro Fill on the back two batteries only, but I do use the pump to fill the front two batteries anyway. It all works fine for me. I would agree that it is pricey but where there is a need, it is worth the price.
