I take my van for a week or more without recharging the battery and there is plenty of unused power. Best price around for such a high quality product. Highly recommend


I gave this battery a thorough test to confirm capacity and max current performance. I found that it exceeded the published specs. I got well over 100 amp hours out of the battery before dropping below 12 volts and found I could draw over 100 amps with no problem. This is an excellent battery for the price and weight.

This battery is light weight and easy to install in my motor home. I'm ordering a second one to double my power. I am satisfied with this battery!


These are great I have an RV with a residential refrigerator so I have 2 batteries originally and added a 3rd. 2 years later bone is bad and we are struggling with weight since we live in the RV full time. 2 lithium batteries and we have more space less weight. It's great and these 2 last much longer than the 3 lead-acid batteries I had. Love them and at a great price.
