Battery Type Comparison || Lead Acid VS NiMH VS Li-Ion VS LiPo

In this VS episode I will compare the gravimetric and volumetric energy density and the price of lead acid, NiMH, Li-Ion and LiPo batteries with one another. I will also talk about how dangerous each battery type can be and what kind of battery you should get for your next project.

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 !

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.

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.

[georgegibson]

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

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

[LazerLord]

Li-Po is great for high-power discharge!

[akhurash]

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.

[Slava-omsz]

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.

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

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!

[cucumber]

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

[jamesslick]

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!

[donaldfilbert]

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

Nice video.

It would be great to see a chart of the information in this video as well as peak power, capacity variations vs. pwr output, power and capacity vs. temperature, lifetime cycles, capacity change as a function of time and charge cycles?

[chronophagocytosis]

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

[caesium]

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.

[dachew]

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.

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

[silverst]

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

I really can't understand why anyone thumbs down videos likes this? You should have to say why you dislike it and it be in a separate section for it to be easily seen.
