These high-quality XT30 caps are 3D printed from TPU for flexibility and durability. Caps are colour-coded to show Charged, Used, and Storage, and the perfect fit helps the caps stay on the XT30 connectors to prevent potential shorting.
This is a good product. It makes it easy to help keep track of your batteries charge status for knowing what has been used, freshly charged or in storage mode. The caps slip nicely on the battery plug. I’m very pleased with all of the ArmSoar products and customer service!
