The reciprocating saw is a real powerhouse. I take them even with the Biomimetic 300 special leaves for green wood in order to cook smaller trees in ER and then disassemble. That goes quite fast, much quieter than the chain saw and also report no. Moreover, the neighbor looks so flabbergasted nice, so because the tree is broken down so quickly and quietly ;-). Large batteries should have for that great piece already. Although negative action on that weight, but in the good piece you have so much machine in hand, that a few grams more noticeable not really negative for the large battery!
