Li-Po is great for high-power discharge!

Making use of the ukposts.infoUgkxcJ22tnHH9l1vjdIdEIG27iOG55P7LXI8 reconditioning plan, I just saved 2 auto batteries from being completely junked. The guides were very simple to follow. I wish I would have found this years ago! You may use the guide to recondition any battery type

4:38 use neodymium magnets to get these clamps on a single cell? excellent idea, why i never thought this way? thanks for the tip.

fantastic video bro! it got pretty information-heavy in the middle, but your summary at the end was perfect for understanding. keep up the good work!

Battery life (charge cycles), Rate of self discharge, Charge efficiency (energy in vs out)can be factors in the choice too.

As usual, another great video. Thank you for spending your time to provide us all these information

As usual - excellent information!! Well organized - concise and complete - and totally relevant !! Thanks a ton !!!

Wow! A perfect quality informational video...the best I've seen out of thousands.

Bro, this video was a great review. Thank you for sharing!

This was the exact video I needed for assurance on my NiMH battery, thanks a lot

If the test would have been conducted with a 1C discharge rate, the LiPo would have been the incontestable winner because of it's low internal resistance. What more, after years, the internal resistance of lithium batterie do not increase as much as other technologies. For those two reasons, after a while, the winner in each categories (even the price) is the LiPo for a high power device as an eBike :) Nice video, usefull informations !

Very informative! a good clear comparison of battery types and the reasons for each. Not every day you get a comparison of tech without "fanboy" hype! thanks!

this video is great! really puts in perspective many aspects of why you should use different kinds of batteries in different applications.

Very slick video which answers a lot of questions. Many thanks.

Really enjoyed this video. Great comparison!

Thanks bro ! Your videos are always helpful ;)!

Thanks! This is exactly what I was wanting and super helpful.

you are the best... no one explained it that easy an fast... thank you, and it is true you are great scott! 👍😉

Good video. You could make video about those batteries abilities in cold/hot weather. Power outputs and etc.

Awesome video, Scott! Congratulations!

A very well prepared and presented video. Good work.

Thanks for this nice summary video!

Fantastic Video Dude. Very Cool. Keep up the great work. Nick.

For the algorithms in charge, this is evergreen content. The whole channel is an international treasure ❤

Great video. You always describes in clear way and easy to understand. Try your best. Thanks

I LOVE YOUR CHANNEL SO MUCH!

that was really the information i need to know ... thank you

Very interesting, couldn't follow your math, however, you explained all very well. Good job!

Thanks for making this video it helps alot.

That was great, but I was hoping to so find out more differences in how these technologies behave. For example discharging while not in use, capactity decrease over time and after X amount of recharge cycles, etc.

Very nice video!!I waited for your opinion of battery types becouse your one of my favourite youtubers.In my opinion i choose the Li-Ion types ,one of my friends brought me a lot of them.Keep up the good work!

Very informative! Thanks for your video.

400K subscribers! congratulaions! keep going )

Good video. I have recently found a smashed ps3 controller outside with a lithium ion battery in it. It was not discharged below 3 volts, after charging and testing i have a good battery for my next project :)

I love your vids keep up the good work :)

While I was watching, my wife noticed that you are left-handed just like me. But with a pretty hand-writing tho.

thank you ! thank you ! thank you !, that's very helpful for me. good job :D

very thorough and well presented

You are making awesome contents.

Well done as usual!

I love that magnet idea

You might also want to consider operational temperature for charging and discharging. For instance, in an outdoor installation in cold weather a NiMH will probably win at all times.

thx m8. really helpful video

Nice and helpful video, can you advice which one is for mini quattro project or elec-bike??

when you were measuring the lithium-ion cells and that 65mm dimensions with a calliper that gave me goosebumps as I thought you were about to short it out.

nice explanation , love it!

Great job and study, keep the good work... One more point better to be taken into consideration while discussing the cost is the lifetime of each kind (in other words its number of cycles before loosing 20% of its nominal capacity)

Very good video! Congratulations

excellent comparison!!!

Wonderful video! Next time include supercapacitors too, although they are expensive and have low energy density :)

Thanks for your effort

Thank you very much for the explanation and knowledge,。

Thanks for educational video, I just dismantle Li Po/battery... It is smell, itchy and hot when touching the layers!!

Very good and helpful , thank you.

Great scott yours videos is great

Nicely Explained Well Done!

You are my role model 📺🔋🔌🔦

I'm using a lot of NiMH batteries from Ikea ($7 for 4) and Aldi ($6 for 4) plus a few power boosters to power my Arduinos and they work just fine.

Bro you are amazing 😇

ready for the video

thank this really help!!

Great overview!

I would have liked you to cover the effect of temperature on each variety. Still, very good video and analysis 👍🏻

muchas gracias ,hoy aprendi algo Nuevo

Excelent video! Thanks !

Can you do a tutorial how to use multiple Li-Ion cells in series within a portable project? (like speakers or something) Including charging circuit with an external powersupply, balance circuit(-board) etc. That would be very helpful!

Very well said sir.

thanks for all advices and informations, I appreciate all your projects. However, what do you know about hall sensors. Can you explain it in a video?

your video's are fantastic

Amazingly made video.

hi I love your chanel, the idea think that your chanel is very entertaining & informative.i would like if you took a look at the udoo x86 & made a review & comparison to other board thank & keep doing what you do

I have old Sanyo 18650s from IBM laptop battery in my portable speaker, I discharged them to 0.05v... But without problems I charged the speaker to 4,2v and t works again like a charm :D

I think one more advantage to using lead acid is that they perform better in colder conditions than the other types. By perform I mean they are not as susceptible to temperature changes as the other types.

Great Video!

great useful video!

Very good video, more like this please, I like

Great vid!

Great videos!!

This is really a good way to look at battery power. I use 18650 type cells due to there energy. Lead acid batteries can be dangerous as well. When charging they give off hydrogen gas, that can explode if there is a spark, plus they contain lots of lead and sulfuric acid, so not really the safest option. The 18650 can be dangerous, but as long as you are careful with them, they can really be useful. They are getting safer everyday and they are getting more out of them as well. I look forward to seeing just how much better they can get.

Great Video Thankss

I have almost 15 years old 12V NiMH (1500Mah) Battery pack , it still working well .

very informative!

Great video 💪💪💪💪💜

Worth mentioning also the big difference between a car battery and the deep cycle battery shown! To complicate even more, you can now get "lithium-ion" aaa, aa, 9v ect. batteries with micro USB ports in them for charging!

Nice video, thanks.

Number of expected cycles, high vs low discharge current requirements, charge time,... may also be things to consider.

What type of battery should one uses for having external battery for camera speedlight/Thor's Hammer flash? Again, making it & feeding it voltage into the flash.

Great video! What about safety and lifespan around salt water? (Like on a boat for an electric motor?)

Your use of SI units was pretty good, but I would still have used J instead of Wh. Anyway, keep up the good work!

nice video ...does any batteries emit toxic gases or vapors ?

There's also supercapacitors, which can be useful in some low capacity applications. The digitizer pen for my laptop uses a supercapacitor instead of a chemical battery, and it recharges in 15 seconds.

Great vedio!! BTW I have a doubt - in Li-PO batteries u showed us the 3 batteries together with a current reading of 4.1 amph. then what would be the reading of a single cell in it. Help me with the calculations.

Nice comparisons. Would it be helpful to add a 5th point about storage life? For example, lipo's shouldn't be stored for long fully charged, but should instead be brought to 80% capacity. And lead acid has very good shelf life.

Will you ever do a video on sdr?

I like the video! However, you should make a note in the description saying that these are all rechargeable batteries. as the NiMH "should" be 1.5 volts

It interesting that you chose the 2450mA NImH batteries branded as Sanyo. I believe Panasonic now owns that brand and the average capacity for them are 2100mA. The price point is also different, cheaper then what you noted. But in the end I don't think it would affect your over all graphing.

Also how many amps you can draw at once is a factor, that would benefit the lead acid ones, hence being so good for starting a car.

Great scott i wonder how would remember these large quantity of sooo much complex formula 😁😅

I saw that some people also mentioned, LifePo4. They are lower in power density, but: They are safer, easy to use, and they are 3.2V almost constant. This save the DC-DC in circuits and also makes it simple to charge. Check them out!

One thing you should always take into account when looking at the different batteries and the prices it the amount of cycles you will get out of them. Yes lead acid is cheaper when you only look at the initial cost but you get a lot of cycles out of them and will result in replacing them on a regular basis. Li-Ion can give you a lot of cycles depending on the quality and they have a higher DoD than most batteries thus giving you more usable energy. Lead acid typical DoD is only 50% and when discharged past this point (that you can do safely) will drastically reduce its life time and could cause permanent damage to the unit.
