anyone with hard to get to batteries really should look into this product. my 2 6V batteries are located in a very small compartment in the side of my trailer. this compartment was designed for 12V batteries but the 6Vs are taller and even just checking the water was alot of work. did it once and after cussing and smashing several fingers, i decided hell with that. purchased the Flow-Rite pro fill RV edition battery watering system along with the filler bulb from camping world earlier this year. finally installed it yesterday......this set-up is badazz!! no mess, no muss, easy to install and all the cells are perfectly filled. the stuff might seem a lil pricey, but IMHO its well worth it. i highly recommend it! there is sytems available for both 12V and 6V systems

Flow-Rite watering system

I've bought one just havn't gotten to hook it up just yet... If works real well, I'll have to buy a bunch more the rest of the battery banks!

That's a great idea!!!!!!!!!!!!!!

My batteries are easy to get to and I still think this system was worth every penny.

been there done that have had them since i owned my trailer....i run 4 six volts
