Muy buena batería para mi sistema de respaldo de cámaras e interneth, compraré una de más capacidad para otro UPS excelente diseño y buena marca

I bought two batteries about three years ago and they worked great. And then I bought a third battery 6 months ago and all three batteries have worked excellent. I’ve had no problems. It’s nice to have the energy. I would buy from these people again. They answered the phone.

Junk. Stopped working shortly after the one year expired. Seller don’t care. They said they were sorry! I say they are sorry!

I was quite surprised at how light in weight these batteries are compared to the deep cycle batteries I was using in my boat. I'll be buying two more for my smaller 12' V-bottom boat. The smaller boat I have to really watch my weight as I load the boat and when I'm on lakes where I can only use an electric motor, I've had to lug a heavy deep cycle battery, These batteries were so light I carried 2 of them down at a time to my pontoon boat. I use one for the trolling motor and one for the anchor winch. I've been using them all summer so far and it's not died down as a regular deep cell battery would. I even had a problem one night with the gas engine not starting and I had to use the trolling motor to get the 24' pontoon boat back to dock. I would estimate that I've used the trolling battery for about 18 hours so far and it still powers my trolling motor as it did when I had it fully charged. I did read that I could hook the two together in either series or parallel, I suggest reading up online on the advantages and disadvantages of both hookups. Next summer I think I'll buy 2 more and hook 2 in parallel to each of my devices and see if I can make it through the summer. I also thought about getting a solar panel to charge the batteries, that way I wouldn't have to worry about taking them off the boat till it's time to store them for the winter. I'll update you on how they handle solar charging once I do that. The only drawback that I found was that you have to use electrical terminals to make the connection as the terminal posts are too small for conventional battery cables to hook to.

Muy bueno
