As the XR FLEXVOLT battery is one of our highest capacity batteries to date, we have also developed an innovative transport cap to allow the batteries to be moved around easily. The battery transport cap separates the strings of cells so that one battery pack assembly can be classed as three battery packs during transportation; for road and rail transportation inside of the European Economic Community (EEC) the battery can be shipped under special provision 188 of the ADR Regulations. If the battery transport cap is not used these batteries will be subject to Class 9 dangerous goods regulations. These regulations apply to Li-Ion batteries above 100 watt hours (Wh). Watt hours are shown on the ratings label of on the underside of the battery pack. The XR FLEXVOLT battery pack must have a transportation cap fitted whilst it is in transit.
