Bryan95 reacted to PierreJ in Youda's off-grid LABI bought 5 US2000B batteries in March of last year. Two of them have since failed and were swapped out under warranty. The service from Pylontech was excellent, and the swapout process was painless in both instances. However, it is a bit concerning when you have a 40% failure rate within one year. I am hoping this was just a bad batch, and my experience is not indicative of the reliability one can expect from Pylontech batteries in general.
