Great for RV’s, camping, and remote energy with solar systems.
I have two of these that can be linked or run separately. They are the European version so they have inverters with them, but the work flawlessly. I bought them new and they have never been truly used. The link below talks about them. They are 1200wh of use each. Full life and are ready to not be just sitting in my basement. Bought for $900/ea new two years ago.
