Featuring rounded and chamfered edges, they are smooth on the fingers and battery case during use. Changing batteries is literally a snap as the levers lock into place. No more need for tools to remove or install your lipo!

Designed for use with AE B74/T74 using the STOCK Battery Brace. Simply remove the current battery brace and hardware and replace with the Darter Design Upgraded Battery Levers.

The included spacers also allow quick Weight Bias Adjustments. Simply snap on the spacers around the battery posts. Each Spacer is labeled on the front for easy ID of the distance.
