Flow-Rite Controls On-Board Battery Watering Systems, 48-Volt Kit for Six 8-Volt Batteries

What a great idea! Filling the batteries was such a chore (no room for the auto-fill jug, have to use a flashlight and a mirror to try and manually monitor the fluid level with the silly bulb filler, getting filthy with the caps and gunk around the batteries, etc.)Tip: As I believe I mentioned in my review of the other Flow-Rite I got, you'll get the hang of knowing when to stop pumping after you've done it a few times.

The media could not be loaded. System was super easy to install. Only tool needed was hose cutter. Everything delivered complete and undamaged. Unit works like a charm. Love it. I'll take better care of my batteries when I don't dread it. Couldn't be more satisfied.

Easy to install and fit only problem is when u fill it on a couple of cells a little water comes out vents like the float valves are sticking or not sealing correctly will watch to see if they start working better with use I could have possibly squeezed bulb to hard

Does not fit trojan batteries T-875. As you can see by the picture they are too long to fit into the battery holes.

The Flo-Rite battery filling system is very convenient and works well. It was relatively easy to set up and connect. I deducted one star because is is pretty pricey for what it is. I can only imagine what the profit margin is on this item.
