Comply with FAA regulations when traveling by air with these XT60 caps, or use them to keep track of which batteries are charged or depleted. These XT60 caps fit on the battery connector preventing any chance of a short across the terminals. Printed in TPU, they fit snug so they don’t come off in traveling, but their flexibility means you can pull them off quickly and easily when it’s time to fly. The Green and Red are great for marking for indicating whether the battery is charged or depleted. Use a third color to indicate storage charge.
A set of 10 XT-60 caps printed in TPU. You get 10 caps for $5.
