4 Stars
This is perfect for a small portable solar setup.
I like the small size and light weight.My only concern is conductivity and durability of the aluminum contacts.The only thing I can think of for improvement is having an internal self heating element to operate or stand idle safely in negative tempuratures. I'm not sure if that is why they are able to make them so much smaller than the full size 100AH version.Overall very happy with the product and the price!

5.0 out of 5 stars Lasted only 9 months ~ update
Reviewed in the United States on January 16, 2024
I used this battery for my live scope and it lasted only nine months. Used it on the water maybe 10 times. Very disappointed. Won’t even take a charge. Turns out it was the cheap lithium charges I got for $24.00. Battery seems to be fine after it got hooked up to a new charger.
