These are the LG pouches. They are 48v style arrangements. Then they buck the voltage up to 400v. This method isn't used anymore in the industry for residential. Most are switching to just the 48v straight to the inverter. As well as switching to lipo4. If you have no cell failures the lifepo4s will last longer for time of use load shedding. If you just doing backup shouldn't really make a difference

Eco worthy's prices are sure tempting, but it only offers a 1 year warranty which concerns me. At least LG offers a 10 year warranty like most other battery manufacturers.

From reading the LG website, I believe this is a lithium ion battery.

Quote from PeteyTheStriker :
Hmm the eco worthy has a little less capacity (14.3kWH) but is also $350 less before taxes.. I dont really see any reason to pick the LG over the Eco since compatibility wise the Eco seems to be universally compatible with most inverters. I dont recall if the Eco is UL listed for permitted projects, guessing the LG is since its listed for commercial projects? Overall cheaper than a Rixu so maybe the LG is the sweet spot if you want a self contained power wall like this instead of making your own battery bank for even cheaper.

Having a US-based company that supports the products they sell is a pretty big deal.
So is having a UL (or TUV) listed product - which eco-worthy (and other cheap 'bottom of the barrel') products don't typically have. Warranty support is also minimal/questionable from eco-worthy.
