Revolution Design Racing Products have introduced new aluminium battery post set for the XRAY XB2 and XT2. The RDRP parts are machined from high-quality 7075-T6 aluminium and they sport a finned design for cool looks and a low weight. Thanks to their design and the high-quality material used, the posts allow for a more secure battery mounting. The parts come black or orange anodised, with machined silver edge details and their visual appearance matches perfectly with their XB2 ultra servo mount. With the M3 thread the XB2 aluminium battery posts are usable with standard or aftermarket battery thumb nuts.
