New Greenworks 80 volt Li-Ion battery garden tools

Re: New Kobalt 80 volt Li-Ion battery garden tools

Looks like Lowe's is now selling basically the same 80 volt line of garden tools under their Kobalt house brand name.

Shop Kobalt 80-Volt Max Lithium Ion (Li-ion) 21-in Deck Width Cordless Electric Push Lawn Mower with Mulching Capability at Lowes.com

The lawn mower is already in stock at my local Lowe's store.

Here's a promo video.

Yes, it is all about capacity.
It is much easier to store "volts" than it is to store "amps"
Higher voltage means less current so it becomes more efficient.
Now the interesting thing is the resistance of dry human skin is about 14V .
This is why cars stopped at 12 V.
So 80V is well above the resistance of sskin so you would hope the insulation is working well and don't use them in the wet.

Hold still wasn't that one of the reasons why we started to use cordless in the first place.

anyone know if this or some other 'system' has or will add a shop vac and home vacuum cleaner to their tool range?

It would be cool to have a cordless home vacuum cleaner and even a shop vac should be doable. maybe they could team-up with Eureka or similar and offer those items. I think Hoover has a lithium cordless vacuum that is quite popular.

Yes, capacity is the key. According to the website, the battery is only 2Ah. So even at 80 volts, it's not going to last all that long.

They don't specify the number of cells, but it is probably 20 cells so fully charged it will be 84 volts (4.2 volts/cell). The nominal voltage will be 3.6 x 20 = 72 volts. Multiply by the 2.0Ah and it is only 144 watt-hours.

For comparison, the Black and Decker CMM1200 came with a 24 volt lead acid battery at 18Ah with 432 watt-hours. Of course with deep cycle lead acid you should only discharge to 80%, but that still leaves you with 346 watt-hours. That was probably 8-10 years ago!

If they supply you with 2 or more batteries then it starts to make more sense. The higher voltage will lead to efficiencies with lower currents, savings with higher gauge wire, and less line loss.
