The amp hour rating for yellow tops at the discharge rate you will be doing is less than 55aH which is the 20 hour discharge rate.......maybe 42aH is more realistic......Odyssey PC1500T are rated at 47.3 A for 1 Hour to 10.02 V but rated at 62aH for a 10 hour discharge. 6 of either is close to 300# so the bike will be 400+ without the rider. I measured my WH/mi to be 87 but I never go above 50MPH and there are not too many stops on my round trip.
