    Best Batteries On the Market

    Posted by Susie on Feb 20th 2024

    I have three of these and the simplicity of the connection and the SOC indicators are perfect for our off grid home. They charge up very fast and even charge on cloudy days. I run apt size washer and dryers, coffee pot, tv, lights, pumps, etc and have only had them get low enough to run a generator one time, and that was after 5 or 6 days of heavy fog and rain.

    Life Changing!

    Posted by Susie on Aug 7th 2023

    We have struggled for a couple years with our Trojan deep cycles. Every winter we would lose a battery. We were at the point we had to be very careful just using a light. But THESE. THESE BAD BOYS ARE THE WAY TO GO!!! We started with one, now we have two and we plan to get more. I cannot explain how big of a change this made. Our cabin is No Grid, and now we can run the AC, have the fridge set above 2, use the ceiling fan... it's a miracle. And with the 30% tax rebate we it was a no brainer. The connection to the batteries couldn't be nice. A push on connector. No lugs, bolts etc.
