Totally agree. Forget autonomous cars, try an autonomous drone mower service that can go house to house and trim lawns without spewing hydrocarbons!
Cool idea. Autonomous delivery vehicle pulls up and pro robotic mower self deploys and cuts the lawn. It can be any time of day cuz it's all electric and silent. Back on board the mower swaps batteries and gets carried to the next customer. One pro Mower handles a couple dozen lawns, and the entire process has no direct human involvement.
Lucky for Husky they didn't compare prices in that review.I ordered a Husqvarna 430x Automower with a starter kit of wire. Plenty of reviews on youtube like here:
Previous attempts at going electric in the yard were met with disappointment. Low power, short run time, etc. Time to try again.
I'm kind of looking at this from a system standpoint to share batteries and chargers. I think I'm down to Echo and EGO with EGO currently having the edge based largely on a wider selection of battery options and more powerful batteries. Consumer reports review of the EGO mower indicate that it may not cut evenly which could be an issue unless I let go of a bit of lawn perfectionism. Uneven cut seems to be an issue for all cordless mowers though.
I was once a fan of Bosch but have heard some worrying things about their more recent offerings and the Pro series cordless stuff is only 36v which I assume (and perhaps a bad assumption) will provide much less power, particularly for things like mowers and chainsaws. Their pro cordless stuff is also hard to find in the U.S.
I'd love to find a comprehensive review that looks at all of the tools of each system but no luck finding such yet.
Depends. Power is voltage x amps, so 36V x 100amps = 3,600 watts, 80V x 45amps = 3,600 watts. Higher voltage means more cells in series, which usually translates into lower amp hour capacity, so less current output potential. (Assuming a similar physical sized pack and same cell chemistry.)A 36v battery cannot generally produce as much power at the shaft as a 56v or 80v though correct?
A 36v battery cannot generally produce as much power at the shaft as a 56v or 80v though correct? EG, when it comes to pushing through thick grass higher voltage is important? Or is it purely watts so lower voltage with higher amps can produce just as much power at the shaft?
Higher voltage can also help alleviate overheating problems as on a watt for watt basis higher voltage allows lower amps?
Unfortunately Stihl fails for me due to only having a 16" mower so I didn't look much more.
I wonder if the battery folks at Echo and EGO drive BEV's? Ummm.
Those last two sentences are non sequiturs. On the one hand you say wattage of the battery is what is truly important but then your next sentence suggests that energy capacity is more important. It sounds like you're confusing watts and energy.The voltage is only one piece of the power puzzle. Wattage of the battery is what is truly important when comparing batteries. A 36 volt battery can contain significantly more energy than a 80 volt battery.
