Good deal. The best deal I could find 2 months ago after like 3 hours on Ali was 100ah 12v Eco Worthy for $125. This is triple the capacity for double the price.

I'm still seeing the deal price. This brand is a good Chinese value brand. Well known and highly reviewed in batteries.

That is a good deal too. Too bad I already bought my off grid system. But my Eco Worthy batteries are great for the price still.
