Bezerk have introduced their new slim pack battery hooks system for the Xray T4 range of electric touring cars. The battery retention system was designed for the new generation of slim battery packs, like the Sunpadow slim pack, that help to bring all the weight closer to the centre of the car, especially compliments the newer generation of lighter ESCs and motors and still retain weight balance. The battery posts are located as close to the side of the battery as possible to reduce the stress on the upper retaining tab. The 5mm thick carbon fibre battery hooks are beefy enough to take a beating and high enough to keep the battery in its place. The mounting holes are slotted to allow a small amount of left/right adjustment. The 3mm carbon fibre upper tabs look minimal in size but due to their placement are more than up to the task. The kit is usable with the 2020 down to 2017 variants of the T4 and it includes two battery hooks, two battery tabs and two black alloy hex standoffs. Other options include shorter standoffs for very low batteries and are also available in silver.
