We are proud that ReFlex™  is the first Flow Battery to also receive the CE marking! In addition to the UL certification, ReFlex™ has undergone a ‘conformity assessment’ by an independent auditor (TUV) who formally declare that our battery product meets EU standards for health, safety, and environmental protection. With a CE marking, ReFlex™ may be sold freely in any part of the European Economic Area. Not only does this mean that ReFlex™ is safe to operate and maintain, it also means that the battery can be insured.
