We searched for a long time to find a battery strap that had good strength yet didnt turn to fluff when used hundreds of times. The result is this TURNIGY battery strap, made from high-end polyester and nylon hooks. It wont break down when used often yet still holds batteries firmly.
With 330mm of length this strap will even hold large 8S packs.
