So, my two year old factory-installed house batteries kinda crapped out on me. I can’t put all the blame on the cheapie Thor batteries. My maintenance of them was piss poor too. Well, I bought two new 6V flooded deep cycle batteries and I promised my self that I would do a better of maintenance on these.
So, today I installed a battery watering system. It uses a bulb pump system to draw water from a jug and fill all batteries at the same time without removing any of the caps. Worked very well on my initial topping of the batteries. I think I’ll like it.
