I thought Collin's lab ended years ago...my life is complete again. I'm super happy to see and know this series is still alive

Anyone can teach about batteries; The presentation and production in this adds so much value. Kudos to Collin's acting and comedic timing, and Ladyada's obvious knowledge on the subject matter.

are you freaking kidding me!? this is collins official youtube channel!?!?!?!?!? OMG!!!!! years ago after he was in the make channel, i spent days looking for his official channel and was bummed out I never found it, and now while doing some random search about some electronic components I stumbled uppon his old videos and then searched for collins lab again and this popped up!!!,dude! you are freaking awesome! I loved the videos you made with make, and I sure as heck am subscribing! you should be an electronics teacher, I learned more about electronics than in the technical school im still paying for an Electronic Systems Technician certificate lol, keep up the good work!

WOW! Great part 2 on batteries. Obviously we could ask to know more about the many kinds of lead acid batteries, LiFePOs, and NiCds. But maybe it would be better to do a wrap-up on the failure modes of batteries. E.g. how did Samsung get into this mess with the Galaxy Note 7? Why won't my car start when it's -20 C? Why are there still NiCds? Why can we only fly drones with LiPos? Does it even make sense that Tesla PowerWall is a lithium battery when it doesn't matter how much it weighs? And many other engineering design questions I feel you could answer very well! :) Thanks for all the great knowledge so far!

Fun and informative...not too mention "free of charge"!!! I wonder if you might go into the topic of how to figure out "battery life expectancy". I understand that amp hour ratings are done differently now by company's than they were in the early part of the last century. Apparently there was a Peukert number/formula used to help get a more accurate prediction of battery life. A more recent formula by Chris Gibson of SmartGauge Electronics takes into account the modern method of amp hour rating. I read details about this on page 12 of Charles Platt's book Encyclopedia of Electronic Components Vol 1, however, I found information on batteries from manufacturers often lacked the details I was searching for and there were very few examples in Mr. Platt's book to be clear that I was comprehending the process. I believe he wrote that a simple rule of thumb was to divide the aH rating in half... What say ye? Again, thank you for the ongoing videos. Let me know where to contribute, please!

This video is very well made. Very interesting and I love the hosts and their performance! It brings a good light on batteries, especially for hacker and maker who just get into the field, or people wanting to know more about them. The only thing I want to point out, is that a dropout voltage of 1.2V in alkaline batteries is a bad way of engineering. Alkaline batteries typically drop out at 0.8V, so considering them dead at 1.2V wastes a lot of usable energy. Unless of course, the open circuit voltage is used to determine that. But that is another can of worms.

No mention of Ni-Cad or the reasons to select a general chemistry type. Ni-Cad has about half the total energy storage of NiMh and needs some care in disposal, but they are unique in their very low internal resistance and potential charge and discharge rates(some as low as 15 minutes); which when designed for fast cycling, are several times faster than Li-ion (best 1.5 hour) or NiMh(best 2-3hour, a magnitude slower), if your project has a battery size limit and needs a huge burst of power Ni-Cad is still a top option. The other unique bit is that Ni-Cad can and even should be stored fully discharged while most other types should be stored charged, kind of a niche requirement but still to be considered. The whole memory issue was basically an urban legend based on a misapplication of some satellite battery research. What people think is cell "memory" is actually damage from cheap poorly designed chargers that keep "charging" after 100% or battery packs that allow a cell or two to suffer a reverse charge at some point. The real memory issue was a rather minor effect and caused by thousands of absolutely identical charge/discharge cycles such as seen in the orbital period of a satellite. Alkaline has very high internal resistance so is no good for fast draw down but for veryt low current apps it has very low self discharge even over years. Silver oxide are a top choice in cold winter weather. Lithium(metal single use or ion rechargeable) due to their high energy storage density and moderate internal resistance and charge cycle can often take the place of both NiCad and NiMH, however they cost more and the lithium-metal type are not allowed on passenger aircraft.

Would the solar charger work for smaller cells? I have a couple smaller cells from stuff I've taken apart that I'd like to reuse, but there's no way they're 12v, and don't have the solar connectors.

Can't really find recommendations which battery to use for DIY/IOT products. E.g. Is it better to use 9V to directly drive motors and buck converter for microcontroller or to have Li-ion or Ni-MH and boost-up converter for motors and some converter for a microcontroller. What is the difference in maximum/minimun current consumption for the different battery types?

so what changed with the 3.6 3.7v thing? like its chemistry how could it have changed? also why cant we mix types if the full and empty voltages are the same? im assuming you were refering to parallel right? obviously you cant in series.

If a battery can do 1A of discharge.. does putting it in Parallel ADD the total current? E.g. 2x 1A Battery in Parallel gives total of 2A discharge? or is it in series?

great vídeo,It came in Hand,i need Help on It because in planing to make a powerbank like to my raspi, so im Search much because i can use many li íon baterry of 3.7 together and down the Voltage,but How can i recharge It later? so You guys showed that i can recharge via USB,them comes 2 questiona: 1- its 3.7v baterry to Feed raspberry pi on vídeo,is that ok,i mean 3.7 to 5v is low and can overheat the baterry 2- for recharge via USB its 5v in 3.7v baterry,wont make problems because its higher voltagem than baterry support. or can i use an Voltage balance ?
