Thanks for the video! :)

Whaaaaaat?

Very good video. I was beginning to think high c rated batteries were just a marketing thing although I still do to some extent when talking about the same battery chemistry.

The ploymer battery will only last about a year. Whereas the Lithium-ion batter will last over two years. If manufacturers had to state the expected lifespan of their batteries, they would use only lithium-ion. Also, when ploymers are used in RC airplanes, manufacturers recommend changing in a metal box for safety.

My battery is on 26 cycles. Is it dying?

👌

Pls repeat this with prismatic cells.

thank you thats a very much detail and simple explanation

Price of smart ring battery

❤❤❤❤❤❤ love it love it

You guys joking. Problems at low temperatures on earth? Now I know why most chemical and biological secret laboratories are only in Alaska, Antarctica, nobody at North pole. In Antarctica minus 60 Celsius, at north pole minus 80,nobody can survive there on earth. Really confused, big question now how we went to space, to moon where temperature is at least double minus 160 to minus 270 degrees Celsius. When try to come back fuel isn't frozen? Any rocket or engine don't burn fuel? To burn don't need air? Remember those engines in 70s kick started using crank loads of misfire, or pushed by people? Now I know why 70 years later nobody including AI goes back to explore hostile universe and planets.

I have 3S160P for solar ystem. 12V. I will spend max 10A and charge will be araund 8A. I have balanser, what I need, BMS or PCB? What is better?

Why no comments about LiFePo4 batteries?

this video IS HORRIBLE!!! shaking camera, no data numbers, you dont keep camera still !! cant read numbers!!

Dear Zack. Thank you for the clear and detailed explanation! Just a question...when you said "After the reaction, a thin film forms on the surface of the electrode material where lithium ions can be embedded and removed freely while electrons cannot" are you talking about the SEI itself? or are you talking about the Lithium Plating? I heard that while the SEI is good for the cell, the lithium plating is a negative consequence of the misuse of it, mainle related to fast charge. Maybe I am missunderstanding the issue. If you can please clarify and/or indicate me some material to read about it will be great. I am electrician... not a chemistry... so plese forgive me if I am wrong...

Thanks a lot for this detail explaination.

very helpful. Thank you

Great explanation between the differences. thank you.

Helpful, probably the closest I feel to understanding this topic so far.

运营小哥哥，别生气哦，有问题发现问题，改了，还是好员工。加油，我会持续关注你哦！我也快下班了，晚安

您好！作为格瑞普工厂的员工，很高兴能在油管看到您，作为油管这个超流量平台，且能获取更大的宣传和收益的前提下，看了您制作的视频，我觉得有些许不完善，首先，油管有规定，满足1000个粉丝，4000个观看小时，且在原创的前提下，就能开通平台收益和获得更多的流量展示，更多的宣传机制，但作为运营的您，却在视频中，用了有版权音乐等，这样做视频，是没有质量的。然后，作为油管平台对于发布视频的规则，公司的运营者，并没有 定时 定量 做出有效，突出的原创视频去宣传或者有定位的去推广公司和产品的视频等等。希望公司能得以改进，把油管这个平台利用好，把公司的产品和理念推广出去

The battery on my cousin's scooter is messed up coz she left it outside when the temperature went really low.. now I have to replace the battery for her.. tried to tell her about leaving it outside at night... But nobody listens to me😅 👍🇮🇪

2-3 years, what is this 2007? Even my mobile phone from 2019 still holds a charge for 4-4.5 hours of media playback that I still use most days for that purpose.

Thank you Zac this was helpful 👍

great video. Thanks!

Can you make another video where you add the other explanation of C too might have been something like 10C = 40Ah * 10 A

Wait, so the lithium molecules are the "cars" of e- particles between the anode and the cathode? What makes the lithium to become stuck, and in what layer it became useless, "again, stuck"?

I hate how much you have to baby LiPo batteries... I just found a really nice laptop to buy & then I read that it has a LiPo battery, I just can't deal with having to be extra cautious about it going over 80%, especially since I use my laptop plugged in at home. *ps.* Are LiPo batteries more dangerous than Li-ion? I've read a bunch about their packaging being more fragile than Li-ion & if that packaging gets damaged it'll catch fire or spread chemicals.

Getting an audio editor or learning to do it by yourself can greatly increase the quality of your videos

exactly the info I was looking for thanks

great

Why to work to the communist party? They're genocid3s.

I have a story to tell you! I storaged an iPad Mini 1 with 9% wear level at 2018 with 100% SoC and 254 Cycles. Now it's 2023 and the same battery, "only" 15.90% of wear at 80% SoC. I asssume the battery it's original. I have it since 2016. Edit: If I knew that before, storing it at 50/60% SoC, it would be even less! Here where I live is cold for more than 5 months per year, for about 2 to 9°C at night / 18°C inside home.

I usually charge my phone 16-30% up to 80% is that good?

What should be the ideal ir of 450mah 4s 80c

Great video. Question - can you recommend a lithium battery C-rate tester to purchase. I build ebike batteries and need a solid c-rate tester. thanks. /Bklyn👑

use a battery discharge computer please this is a waste of time.

I just bought a 30,000 mAh Lithium-Polymer power bank. How can I calculate Wh? and Can it be brought on the plane?

Terrible

Does it apply for 2022 Macs?

Hello, how long time need for formation SEI?

So 13.7. Is the charge rate. 13.4 shows you can take/ give a charge easily. 12.6 equals a battery at rest for its specific gravity/load of power equaling full. 1 ma= 1 minute = one amp. 12x12. Equals 144=14.4 full battery. At 77°. Core temperature./ Heat Signature knowen has radiation. Example battery Bank holding 80 amps, one amp per hour equals 80 hours. Then the battery is dead. 8 and 7 equal 15, 15.1 float charge. Which shows Celsius 3.1 degrees/ Celsius. Fahrenheit. Same difference. Just depends on how you want to look at it. Another example would be, cordless charger for your phone is a float charger. Whereas the cord is direct and must be unplugged. One piece warms the battery, the other Cooks It Out,... overcharge. I know same phone lithium battery 22 years old still working. I own a 5-year-old Android phone, same battery no problems with charge or holding charge. It is 12x12 on diagnostics. Meaning no degrading, same as new. If your phone gets hot while working with it put it in the freezer for 3 to 5 minutes cooling the core down it'll be fine.

Please provide me the applications of high discharge rate batteries in more details

I have a question about my phone and it's a Lithium-Polymer battery at what percent should I charge my phone and at what percent should I unplug it? I hope you can answer this thank you.

This video deserves more traction then it has. You did a great job of quickly showing how safe this chemistry is.

Can you retry this with cylindrical cells? In pouch cells the distance between the electrodes increases and 'disable' the battery. But cylindrical cells keep the electrodes tight. Will they start forming pure lithium? Or explode?

thanks :)

👍

Nice info

How does the total energy going into the cell change with capacity fade? In other words, how much energy is lost to charge a cell at 80% SOH vs a cell at 100% SOH?
