Welcome and General Discussion / Re: No Quality EVs Under $60k
« Last post by GuitarStv on Today at 06:21:43 AM »In a quick check I can't find the specs on the manufacturer's websites, but I thought most of these used NMC batteries, or at least not LFP? Current LFP batteries also have lower density.
The Kobalt batteries that I've used which died in under 200 cycles are Li-ion, not NMC. A quick check shows that this seems to be the norm for most all electric mowers.
From everything that I can find online, these Li-ion batteries are expected to last between 300-500 charges or 2-3 years.
I meant Lithium nickel manganese cobalt (NMC), a subtype of Li-ion batteries. There are also bunch of others, I can't keep them straight myself
https://www.xerotech.com/news/6-types-of-lithium-ion-batteries/
NMC is fairly common. Lithium Iron Phosphate I think is less so, but works different (e.g. lower energy density, but less susceptible to thermal runaway. But that is also changing with newer batteries). I only asked because someone above quoted testing of charge cycles for LFP specifically, while we don't know what these mower batteries are. I suspect not LFP.
The article I posted claim 2,000 charge cycles for NMC, and 10,000 for LFP. But of course that depends on use, and quality
Sorry I was specifically referencing the lithium iron phosphate batteries in the mower that I referenced, with a link to the manufacturer website, which states the mower uses lithium iron phosphate batteries.
I did not mean to imply the cheap electric push mowers use lithium iron phosphate batteries - only the mower that I referenced.
Here is a link to the mower again if anyone is interested. https://www.yardforceusa.com/yf56vrx-rer38-li50-riding-mower
It sounds like it is not very common for mowers to use this battery chemistry though.
Ok sure.
But that's also a $3,100 ride mower! :D I don't think (hope..) many in this community are looking at something like that! Why would anyone give up all that free exercise..
Well - true.
I spent some time looking for an electric push lawn mower with lithium iron phosphate batteries and could not find any.
Which is a shame really. Maybe in a couple years there will be an electric push lawn mower with batteries that actually last a long time....
I'd like to think so too, but doubt it. It seems like the mowers act kinda like a loss leader into the lucrative side business of selling defective but expensive batteries with no cheap/easy replacements available.

Investor Alley / Re: buy bank stocks on the dip
« Last post by chasesfish on Today at 04:30:52 AM »If you want a good example for the profile bank I think can get in trouble this cycle, take a look at Eagle Bank's Q1 Earnings
Most of these top 10 / top 20 cities have $10bil to $30bil banks that still act like community banks. High levels of construction lending, high levels of CRE exposure, and ability to do much larger project sizes. I knew a few that fit this profile in Dallas, Eagle is the main culprit in Washington DC. Some cities like Atlanta don't have a candidate because the two that met this criteria sold a few years ago due to retiring management.
These banks weren't formed until the consolidation of the 1990s, so they don't have the same funding cost benefit that the 100yr old banks have. Similar to First Republic and Silicon Valley with a credit catalyst vs. a bond catalyst for the hit.
The feds have always forced these banks to keep a bunch of capital, so the push/pull is going to be just how big are the losses, they can absorb a lot of CRE pain with 10% Tangible Common Equity.

Share Your Badassity / Re: Upgrade Schmupgrade
« Last post by Wolfpack Mustachian on Today at 04:24:47 AM »It's honestly hard to think of things we HAVE upgraded. I'm also very much an opposite-sort where the "upgrade" would actually be a downgrade for me, as I greatly prefer my old reliable stuff. I suppose my Kobo upgrade in 2021 so I could read library ebooks would be my one example of a real upgrade. My boyfriend upgrades Playstations when a new one comes out.
Probably the most noticeable things I never "upgraded" from have been my flip phone and my studio apartment. Both are just perfect for me, but very glaringly strange decisions to other people. I've also never upgraded to a television larger than 30 inches (I think big tvs are really ugly and encourage braindead lifestyles). Most of my clothing is also pretty old - I have a lot of pieces that predate our relationship, and we're celebrating our 15 year anniversary this summer. I also obviously never made the jump/upgrade to a car lifestyle, never got my license or anything.
Reading through this thread I had the same thought. It's hard to think of things I've upgraded deliberately that were fine as they were. In fact, in a way, I've "downgraded" at times, occasionally buying cars older than the ones I replaced that were broke and too expensive to repair.
