How to test batteries without a multimeter

22 Problems Solved in 2022

spawnflagger says...

I've personally seen the GoGoRo electric scooters mentioned #15 - it's a neat idea, and the battery-swap "kiosks" are conveniently located and fast/easy to use.
It's a good solution for any country that already has a large scooter infrastructure (like Taiwan), but don't think it would ever get adopted in USA.

Great to see Tesla getting hammered by its CEO's trolling. Thank you Tesla for bringing EV to the fore of automotive change. but it's time to break that near-monopoly (not Tesla fault though), and bring in exchangeable batteries at gas/e-power stations.

Walleye Tournament Cheaters Got Busted! Clear video

spawnflagger says...

I didn't think it was possible, but looked it up (found this) and modern metal detectors can detect lead.
So there's really little reason the tournament judges weren't running a metal detector over every fish.
(a x-ray would be more definitive, but way more expensive and can't be battery powered)

Why GM Says Its Ultium Batteries Will Lead To EV Dominance

spawnflagger says...

I think Tesla does some innovative stuff - like using the worlds largest metallic moulds (built by some Italian company if I recall, which make those exclusively for Tesla). But ultimately Elon is a "hype man", and most of his promises have fallen flat (check out Thunderf00t's youtube channel - he debunks many scammy startups as well as Elon's claims, using high school chemistry and physics).

I do applaud Tesla for opening additional factories in Germany and China so quickly, but exponential growth (for any EV maker) is impossible - there's simply not enough easy-to-mine lithium in the world. (Maybe Elon is planning to mine some asteroids instead of going to Mars? who knows)

The GM battery tech isn't exciting or sexy, but it is a means to building a more affordable EV. Ford is already shipping F-150 Lightning (assuming its not affected by the same contactor recall as the Mach-E). Rivian has been (slowly) shipping trucks.
Where's the CyberTruck? I bet even the electric Silverado will start shipping before the CyberTruck.

Um…My last math class (besides taking statistics as an elective) was advanced placement B-C calculus, where I excelled. How about you?
And when do you think I said I’m a math teacher? Another delusion.
I told you for approximately the 29th time my work resume just days ago, and already you know absolutely nothing about it. Just wow. Exactly what I said would happen. I won’t say you have the memory of a gnat….that would be insulting gnats and giving you too much credit.
I’ve never been a teacher, I did edit the teachers edition of a third grade math book when I was 13…is that what you’re misremembering?

Elon himself said publicly he plans a 10% reduction in salaried workers including line workers with only 3 exceptions for battery builders, Solar installers, and car builders….but including thousands of maintenance, construction, design, quality control, new line manufacturing, etc, not just white collar, and rehiring hundreds as hourly no benefits workers, not increasing his workforce. Also announced a hiring freeze worldwide.

You answered your own question. I looked up Monro, seems like an internet Tesla fan to me.

I’ve read and watched more than 6 articles or investigative videos in the last 24 hours, friendo. You watched a single video from a guy who’s been shilling Tesla for years.

I say you didn’t watch because they went over how this formulation is not next gen, which won’t use cobalt, but is superior to currently AVAILABLE batteries and has the advantage of being produceable today in large quantities, clearing the bottleneck. It’s also modular, so newer formulations can be integrated instead of full replacement.

Tesla is down 20 30% due to The economic forces not due to TESLA.
My current worry is a recession which will hurt all including Tesla stock price.. We can thank Democrat policies for steering us into this costly mess.



Tesla is expanding rapidly , Or as you indicate I am mistaken?

Q1 production over last few years.
2016 15K Vehicles
2017 25K
2018 35K
2019 77K
2020 102K

Tesla is far less likely to make it through the decade, they were the big fish in a puddle, now they’re a small fry in a little pond that just had the tide break through and now there are sharks in there with it.

Mary Barra GM CEO. Her job is to "say" they are the leader, even when they a are not and wont be. Don't believe her.


There are few YouTube channels to watch on EVs. Sandy Munro is 1 of them.

Ford and GM are the Blackberry of their day.
They may make it through the decade but will be insignificant in the market.


Do you think CNBC would positive spin GM because of all the advertising they do? Would they be 100% honest?

Tesla BLOWS AWAY Expectations. (Q2 2022 Recap )

newtboy says...

Clearly better than you, as I don’t just make up numbers or ignore losses of 1/8 the value and pretend they never happened. Also I seem to know what Elon has stated as his plans for the business better than you, I knew he plans to fire 10% across the board while you are convinced he’s going to expand.

Cherry picking?! You said down from its high this year, I went from Jan 3, it’s high this year, to yesterday’s close. Now you call that cherry-picking?
It’s not about a date , dummy, it’s about it’s high for the year, the point YOU picked. WTF is wrong with you?

If chicken was overpriced by 7 times but other meats aren’t, and then chicken dropped by 20%, it’s still a TERRIBLE buy. Same with Tesla, but chicken isn’t also priced based on how nutty Foghorn Leghorn acts, Tesla is, and Elon is acting CRAZY. I’m somewhat surprised you stick with him, Trump has totally abandoned him and now says Tesla is a terrible investment. Even if you stick it out, lots who listen to Trump are getting out. That’s going to hurt for a while. Another self inflicted wound.

Yeah, sure buddy. Just keep telling yourself that. Tesla is dropping off a cliff, unlike other car companies, and it’s all Biden’s fault (only the losses, not the gains). Tesla’s losses are self inflicted, and there’s more to come.

Growth is good, but you must ignore that it was so insanely overpriced that it really doesn’t matter, the price is not tied to any growth or income, it’s pure speculation…PE still 110. A decent PE is below 20.
Record capacity….but it’s never been close to full capacity so that’s meaningless. It’s still stymied by chip availability, battery availability, and parts availability for their battery factories so they can’t even make their new batteries their new car models require, and Tesla isn’t first in line for chips, Ford and Chevy are. If you could only produce 100 cars a month and now you made 103…that’s record production, but still failing miserably.

Edit: Not a good sign that cybertruck and the electric semi truck are now delayed indefinitely. Ford is going to beat Tesla to the pickup truck market with a truck that doesn’t look like a bad 80’s sci-fi movie prop. If major semi manufacturers do the same, and manage to solve the weight limit issue two expensive product lines will totally fail. Elon is clear, neither will be released this year, next year is a maybe at best….but as designed they aren’t competitive with diesel trucks for range or load capacity.


Yeah, sure, everybody else is hurting Tesla to hurt YOU. It’s not slumping because it’s in financial straights, can’t produce cars anywhere near full capacity (or at a profit yet?), is burning through BILLIONS every month, and has an owner that clearly doesn’t care one whit about tanking the stock with impulse moves like offering $45 billion for a company not worth $20 billion.
I don’t let politics control my investments….and mine have not lost 32% this year, you have (and you pretend it’s only 20% because you lie even to yourself).

Again, if it grows 50% (and I don’t think Tesla has btw) but is overpriced by over 10 times (it was in Jan) it needs to keep it up for 20 years with no stock increase to break even and actually be worth the price. Any stock with a PE over 100 is horrific.

You claimed down 20% this year, then blew up when I showed it’s actually down 32% and massively overpriced. Why on earth would anyone take advice from someone so dishonest with even the values? Especially someone so divorced from reality as you?

Tesla is losing subsidies, can’t produce at profitable levels,and SAID they’re downsizing by 10%.
Yes, the EV vehicle category is due to explode, but Tesla is at full capacity (as much as they’re capable, not full factory capacity) and is about to get MASSIVE competition from the big 3, with insanely more production capacity, better supply chains, and subsidies they haven’t burned through yet. Tesla can’t keep up with demand, but they’re nearly the only game in town….but not for long. Expect demand for Teslas to plummet when electric Mustangs, Corvettes, SUVs, pickup trucks, etc start rolling off the lines in big numbers later this year, EV’s that are on par with Teslas (or better) and that customers don’t have to wait a full year for delivery…there have been multiple times recently when Elon said he would stop taking orders because he can’t produce them.

We had an apple in the home by ‘80, and stock soon after. They weren’t at a PE over 100. They also were doing terribly before they gambled on the cell phone industry. Derp.

There’s a reason you think I know everything….I can read. When there’s a topic I’m ignorant about, I read about it, and don’t just look at one source. I try to get multiple different opinions, the facts, and history of any topic, then reply. You listen to admitted liars and nut jobs Alex Jones or Beck and think you know it all. Lol. Such a silly, constantly projecting little boy you are.

Really….it’s certainly something to Tesla. Yes, I want him to be held to the contract he signed. Yes, it will hurt Tesla more than the $1 billion drop in assets for NOTHING, because it’s an undeniable example of Elon’s recklessness and poor business sense. I don’t care one whit if he buys or not, I want him to follow the contract he signed. If he does buy, though, it might end Tesla. $45 billion from its coffers (for assets worth well under $20 billion) would be a death nail.

MSNBC agrees with me? News to me. I come to my own decisions, little boy. I don’t need them spoon fed to me, and I understand why I invest as I do. I made money this year, did you?
(I know, if you’re honest about being all in on Tesla, you lost massively, 1/3 of your portfolio in 6 months, and you still think you’ve got it all right, you know everything there is to know about investing, so much you spend lots of time being an unpaid salesman for Tesla, a stock that’s losing money hand over fist and is overpriced by at least 6 times according to professionals).

I’m one gullible dude?!? I AM!?! Er mer gerd, that’s some serious hard core projection (and a little tissy fit).
ROTFLMFAHS!!!

How well do you follow Tesla? Most likely you answer is near zero. But you sure have all the answers.


Once again You foolishness is on full display. Cherry picking numbers? Thats ok

I said it was down a great amount. 20% or your 32% pick your date pick you %. Does not matter.

IF chicken was on sale 20% or 32% below normal pricing you would buy? Same with Tesla.


This is due to the overall economy. not from anything Tesla is doing. Tesla is is growing. 84% last year and 70% the year before.

This Q2 growth was only 50% . Mostly due the china shutdown. China is back up and running and at record capacity.



Biden economy and Communist fuckery is holding Tesla down , not Tesla. Hence it is a great buy.

Maybe your just a Union only guy? Thats OK.


Regardless of current stock price., who wouldn't want to buy the stock of a company growing 50% YOY?

I follow daily. I have about 1500 shares in the Tesla. And your are right I am down from that $1200 high. But I'm looking long term. 5 year min. I see explosive growth over nest 8 years.

Tesla goal is to make 20Million vehicles/year. Last year nearly 80 million vehicles were made globally. ICE vehicle sales are declining about 7% YoY since 2017. Al the while EV sales are growing.

What side of the fence do you wan t to be on? When Apple entered phone market they were a computer company. Today they have 20% of the phone market .



Apparently not the great intellectual foolish and ignorant @newtboy , who know everything about everything.


Finally, Now you want Elon to buy Twitter?
$1 billion penalty. That nothing to Elon.

Guess if MSNBC says something it must be true.

Big dreams, but remember hyperloop, the amazing high speed public transportation Musk foresaw?
It was going to be autonomous pods driving hundreds of mph through multi tube vacuum tunnels, now it’s Tesla cars manually driven maybe 40mph through small one lane tunnels, with traffic jams already on the tiny test track ride in Vegas during the pandemic with riders limited to well under 1000 per hour (<1/4projected capacity) costing $52.5 million for 1.7 miles of inescapable death tube…. so underground death trap roads at only 8800 times the cost of above ground roads.
Remember the Tesla semi truck? Sounded great. Turned out it had less than 1/6 the cargo capacity of similarly size trucks because of battery weight and a 300 mile maximum range new (quickly dropping as batteries age) for the regular version, and unless you charge at Tesla with guaranteed discount electricity it’s not even cost effective against regular trucks per mile, much less per ton of freight….and still not any on the road, now estimated to start next year…maybe.

Notice the teslabot doesn’t list expected battery life, which is the big limitation on self powered robots. All the ability in the world is useless if they need to recharge every 10 minutes.

Elon’s ideas sound amazing until you look at them practically, and find that his projections are insanely unrealistic.

Edit: in his genius, Musk lobbied hard against the infrastructure bill that includes money to build the American chip manufacturing capacity…and now his plants are losing billions per year because they can’t get chips.

Waiting for the spec that says it akes 10 minutes to inflate, battery life last 10 mins and 10 more mins to deflate and pack up. All for going 5 miles per hour - maybe.

Might be better to just run for 30 mins and arrive faster to the destination, and not be saddled with a useless backpack.

I'll wait for ver 3.0 before I'm on board.
