This is a typical Charging Harness with SAE connector on one end and ring terminals on the other. It attaches to any Antigravity Battery (or any battery) while the battery is in the vehicle, and has the SAE plug on the other end that mates to the Antigravity Battery Charger, or other chargers. This allows for the battery to stay in the bike and be charged by plugging it in. Also has a high visibility yellow tag to remind anyone that it is a lithium battery and not to charge with a lead acid charger.
