i think i might be outgrowing my pair of 5 amp hour batteries from EGO the problem is the only capacity in their next gen "lithium max" series batteries is 8 AH and it's $600 a pop, and i would like a pair for symmetry ( my mower takes two and hand held tools take one each ) i hope i can survive long enough on my old pair of 5 AH batteries for EGO to release smaller batteries in the "lithium max" series. the "max" refers to new tech, not to capacity.
