*   These rules apply to MPBA FES meetings only and batteries must be in original packaging.  Naviga currently apply weight limits of 110grams for mini classes, 280 grams for 2-3 cell classes, and 560 grams for 5-6 cell classes.  If Naviga bring in the use of energy limiters for LiPo cells then the MPBA FES will follow suit.
