This looks interesting and its good to see more competition. Are they Lipo? What have you heard on the price? I wonder if SOK is getting ready with an offering that might be good??The more the better for price..
I feel like home battery backup is like EVs now, every company is making one. It would be interesting to see how many survive in the next 5-10 years. If you go to the clre, there's not much separating one battery to another. So choosing one is totally on price and availability and what you think on what company will survive for warranty cases.
