This product is a set of 2S LiPo battery retention straps designed for Tekno RC chassis setups such as the SCT410 series, EB48, ET48, and other compatible Tekno 1/8 platforms. It uses durable hook-and-loop “cinch” style straps that wrap tightly around the battery tray, providing strong holding power without relying on rigid plastic holders or screw-down retainers. The set includes multiple strap lengths to properly secure standard 2S packs in different chassis configurations, helping prevent battery movement during high-impact racing or bashing. It is a direct replacement or upgrade part for worn or missing straps and is commonly used to improve battery security and reliability in off-road RC vehicles.
