Smaller than it appears in the photo.

It's hard to actually rate the product right now. I really won't know about it's capabilities until I have used it for awhile. Check back with me in a year.

Enjoying this battery - Brand quality and it lives up to description

I am building multiple portable Power stations and this battery is great for weight and design. It is performing very well and look forward to continued service. Keep up the good work!

Great battery for solar power project!

I have a pair of these 50ah batteries on a small 400w solar array in an rv and love them. Everything about lithium is better and while these are nowhere near the cheapest lithium batteries on the market they are reliable, powerful, and not overrated. My shunt shows I am getting over 100ah from my pair of 50s.
