Have heard of one battleborn failure, buyer called Battleborn in Nevada, they asked a few questions, then sent him a new one and he returned the defective one with no charge. Yes $900 for a 100 a/h lithium is a lot, but piece of mind is priceless. On that note have bought 12 of their batteries in the last 5 years and have had no problems.
