I bought the LM2101 mower, the 480cfm blower and 15" trimmer. The mower comes with a 5AH battery and charger. I bought the other two without batteries then also purchased a spare 5AH battery. Using this combination, the trimmer and blower time are about 45-50 minutes. I leave one battery in the charger, mow then use the freshly charged battery for trimming and blowing. I still have above 15% charge after the last two steps. The trimmer and blower are a bit heavier, but I wanted to get the best runtime while having a second battery for the mower.
