Fenix X1 O-ring battery mount
Fenix have introduced an O-ring secured battery mount for the Xray X1 series of formula cars. The set includes a carbon fibre rear chassis brace that allows to use the supplied O-ring to fasten the battery pack, doing away with the need to strap the battery using tape. The results are easier battery swaps and less chassis tweak. The mount is usable for all X1 series cars.
