Battery Power for Lawn equipment -- is it time?

I would actually prefer a Lifepo4 solution because then I could use it as a spit can for some solar panels and have some limited emergency aux power in a post-storm environment.

 

Remembering NiCd Nickel–cadmium battery - Wikipedia and NiMh rechargeables, for flashlight, camera, power tools etc. it was often quite frustrating when they would no longer charge up, and even they weren't cheap to replace back in the day. The cheap lithiums are similar. But decent lithiums are like the energizer bunny and given the right mix of battery to appliance have amazing power and run time.
The thing about conversions, is there are lots of pitfalls involved and rarely get talked about. I've have talked with others who have done conversions and others who would like to do conversions, I'm one of the latter group, and I've found that the two groups approach many projects from a way different perspective.

Anyone that's done a conversion and shares their own experiences, typically forgets some of the obvious to them details while sharing. One is the product warranty. The other is being able to observe when something is not working normally in a customized conversion. Obviously, to me anyways, there is always a risk factor in custom conversions, and that risk factor is a big part of owning one of those kinds of toys. And when the project doesn't go as planned, if t here ever even was a plan in the first place, it can be and expensive hobby.
Much more so than buying new.

 

I saw identical size spec lithium iron batteries for my lawn mower but they said not for high constant loads or something. So I got the lead acid agm batteries like it came with. There are more things involved besides size and voltage.

 

The one advantage with the OEM batteries is that there will be no compatibility issues.

 

Here's an instructional (?) tube that I think's an update of one I posted here a couple years ago of a dad running after a kids toy he'd upgraded and the toy was faster than he could run. haha ...
Tons of other kid toy conversions on the tubes now too. Some of um are even funny.

 

OK it isn't quite lawn equipment, but it is lithium-battery-powered and it touches on something we discussed a while ago in this thread.

It's an ultra-high power induction cooktop. The idea is that it runs on a regular 120v circuit, and charges up a big internal battery. Then when you need to cook, it uses both the battery and the line connection to power the induction system for extremely fast high-heat cooking.

Several pages back in this thread, I'd anticipated this sort of arrangement in the context of a snowblower. You aren't going to get enough power out of a 120v extension cord to power a real two-stage snowblower. But you might maybe get enough with a hybridized utility + battery system, and for less money than an all-battery system.

I'm not sure I love the idea of a cooking range that costs >50% more than other already-expensive induction cookers and requires periodic battery replacement, but it's still progress.

 

Do the two stage battery snow blowers available now not work?

As for the cook top, I can see the value for homes that will be off grid, but not ones where supplying more current to the stove would be an issue.

 

The extra price of the cooktop might not be a lot more than what I'd need to have an electrician upgrade my service and panel and run a 240V branch to the kitchen. It looks like they're counting on me not being the only person in that situation.

I see that it also contains a grid-tied inverter so that it can "help stabilize the grid" and/or cooperate with other battery appliances they have in development to store energy for the house. But that only works if it is connected to a 240V branch. I can imagine code officials waiting for a lot of new guidance on this idea of backfeeding from a branch circuit.
