When you guys asks questions in the comments of my videos, I'll try to answer them. If there are questions that I think would make a good video response, I'll choose them to do a longer segment. If I choose your question, you'll win a copy of my book The Ultimate DIY Ebike Guide (the paperback or the ebook) or some other prize in the future when I run out of the stack of books I have on hand.

"sneak preak" LOL! bro I love this guy's authenticity, you can tell this man is knowledgeable on batteries and is an unbias media outlet for quality work, Keep goin my guy stay original!

[thomasjaszewski]

As usual incredibly well done. I can't imagine anyone NOT watching the entire thing. I saw and copied Damians chart but you made it real! Stellar stuff Micah! AND I never thought of using a holder like a 100' tape measure for dispensing a roll of strip. I'm copying yours. Another well done piece. Looking forward to more. Where can I buy the book? On the website? Looking to see and order. AND a companion video! Rock on!!!

Micah, thank you, thank you, thank you! I've been searching for this information for days. This just goes to show that good engineering is timeless.

I'm buying ur book. Least I can do for all ur time and passion helping me understand.

What about the parallel connections? How much nickel do they need?

[drewrinker]

What I do for solar is keep the entire pack 100p1s and to get my 29 volts for my inverter, each battery is connected with heavy duty copper bars than serve as collectors and then connected to a brass battery post and connect all 7 packs with 0 gauge copper wire about 8" in length, had this setup for about 5 years now

Can you please put a video for 48volt 24Ah lithium ion battery – when it failed to give the ratted capacity due to failure of one or more cells in the battery pack or BMS failure and how to know the failure because of battery cells or BMS .
Thanks. Michael

Hi Micha, I.m that Aussie that was wanting your Battery Kit, The New one that is coming. Any news on that?
Also, I am having problems getting my head around these 18650 Batteries and how to build them, without burning down my house.

I do have your new book but wanted to see if you could help me out with some answers to my questions. This 2 will no doubt also help a lot of others who are struggling.

A little info on y current set setup.
My Setup is this, Currently a dying 100 AH AGM Battery, 2x 200w Solar Panels Connected in Parallel to a Renogy Rover 30A MPPT Solar Regulator Controller Bluetooth Lithium AGM Gel. All of my Load Leads go through a Blue Sea Systems ST Blade Fuse Block / 12 Circuits w/ Cover and I also have a 30amp Inline Fuse between the Solar and the Renogy Controller. From the Renogy Controller to the Positive terminal on the battery, I have installed a 100amp BusBar with Fuse.
My New System will include everything above, except for the AGM. This will be replaced by my 186590's.
I am using NEW Samsung 35E INR 18650 20A 3500mAh 3.7V. I also have a couple of 4S 10A~100A BMS Charger Protection Board 18650-Li-ion lithium Battery Cell.
1 Ideally, to start with I want to have a 353.5 AH - 7S 100P.
Plus a Pure Sine 2, 000 W This is to run, LED Lights, LED Lamp, Two Laptops and Phone Chargers x 2, to start with.
Q-1 Would this work ok and would I get to use all of it AH apart from the last 20ah?
I am looking to expand that up to approx 1, 000 AH. with an appropriate Invertor to power everything we use. But first off, I need to completely understand the process first.
Renogy Rover 30amp
Q-2 Will this Controller be able to Properly Charge My 353.5 AH 18650 Battery Bank? It does have Adjustable Voltages.
I want to be able to FUSE my 18650 Battery bank. Anyway, I came across this stuff and it looks to be a much better option that the Resistort Wire Option. this stuff is NICKEL FUSE 5P WIDE CONTINUOUS ROLL BY THE FOOT! 18650 CELL LEVEL FUSING. can you elaborate on this at all? is it as good as I think it is?
Q-3 Will this work as advertised and do I still need to use Nickle Strips as well as this Nickle Fuse.

Q-4 Would it be possible for you to build this system in a Vidoe Step by Step with Instructions showing exactly what parts are needed and how to configure each part along with explanations as to why it is done in this manner. And any other information that you can provide along the way, to help complete noobs like myself.

Although I do have your book, which is fantastic, by the way.
But I am more of a video tutorial type of learner and you are one of the best teachers that I have come across,
So I would really appreciate it if you could take the time to put something together in order to answer these questions and also raise any other concerns that might limit the setup.
Thanks for reading this and I look forward to hearing from you.

Graeme

Hi Micah
Excellent information video about building 18650 cell sets.
All explained in layman's terms; I learned a lot from the video.
Looking forward to your forthcoming book.

[faquir]

Hi, in different courant, why you do not have other thiks of nickel ?

[tomamerman]

Why would anyone dislike this video. Such great information

[neerajjangid]

How to decide the wire gauge while assembly of a new battery. And how to convert sqare Mm values to AWG OR SWG. Please make a video on these because i am facing so many problems related to this.

[jensonmarugan]

Your information is valuable, may i know which ni cd, , nimh, AA, AAA, C etc battery brand is good if you buy from amazon.... if you have any idea please share.

[Nabraska]

Hey bro just thought you might like to know that you present yourself really well on the tube .. just pick any subject and I bet you would explain it well . Keep it bro . Plenty of not so good tubers out there . Good to see some can get it just right .

[terrys.]

Hi,
Did you use any fuses for the battery positive terminal?
I am debating whether to have a fuse or not? Should not bms take car of short in the circuit?

[HaowenLiu]

I have a question.
I don't understand that many people seems to use one small nickel tab extended from the parallel group as the output/input terminal for the battery pack. In this case, the entire current for the pack is flowing through a single tab of nickel. Isn't this dangerous?

Hi love your videos

Is there any Nickel strip universal have bought from Amazon brand: APROTII
18650 Battery Spot Welder, APROTII Portable Spot Welding Machine, 6 Gears and don’t know which is best nickel strip to buy any advice

Thanks Paul

[ZackDasilva-zmpr]

Hi I would like to hear your opinion about ternary battery what do you think of it Is it safe.

[DripdropBrewing]

I'm going to create a 60v 24ah 17s battery pack what size nickel would I need to be safe to use? Thanks

[gd.ritter]

So if I put two layers of 0.15 nickel strip, is that the same in the current chart as a 0.3 strip? I'm getting thrown off because the physical spot welds themselves are fairly small so isn't the current still getting bottlenecked there?
