Have you ever wanted to become energy independent?
Have you ever wanted to install Solar Panels on your house or barn?
How about a Windmill in your yard?
What about creating Hydrogen Generation Fuel Cells?
Or maybe you have even considered installing a waterwheel on a small Creek or Stream?
Well that is very ambitious, and highly commendable of you.
But my question to you is how are you going to store all that great power you have created.
Are you going to use heavy Lead Acid Batteries? Do you realize that these can explode! Or you could be Chemically Burned from the Acid! (Considered the most Dangerous).
NiCd batteries, are the next favorite battery to use. Not dangerous unless the seal of the battery is broken.
Lithium Ion Battery is the battery of choice. Even the Car Manufacture Tesla uses Lithium Ion Batteries, for his automobile. By using 16,444, 18650 Lithium Ion Batteries.
So with that information in hand; Many enthusiasts have used this battery as their battery of choice.
Now we will see how you can do this, on a large scale; But with the ability of disassembling the power cells, with out any great difficulty!
Step 1: Power Packs - 18650 Lithium-Ion Battery Module.
18650 (18mm by 65mm) battery is a size classification of lithium-ion batteries. They are slightly larger than a normal AA Battery.
As you can see by the pictures provided, each module can be stacked to increase the power output. By using ohms law we can calculate each modules power.
Step 2: Battery Calculations
Each battery is equivalent to: 18650 VTC6 3000MAH = 3AH; 3.7V IMR Battery / Here is a website that explains the math in calculating batteries in parallel and in series.
Each Module is capable of producing a verity of current ratings. Depending on the output current of the batteries used. But in this case we are using a 3amp battery which will produce 3Ah per board.
Once you start stacking the modules on top of each other you are now putting them in parallel and the calculation is now. Amps + Amps = 2A or 3a + 3a = 6 amps
Each Module is capable of providing 25.9vdc at 3000mah (if that's the battery used) and if we start stacking the modules one on top of the other, the math looks like this.
25.9v / 3000mah + 3000mah + 3000mah+ ect...
A single 10 tier battery bank would be capable of 25.9v @ 30ah /// 3000mah * 10 = 30,000mah / or 30ah
By stacking battery pack after battery pack; all in parallel. your voltage stays at 25.9 vdc @ 30ah per battery bank.
Step 3: PCB 18650 Lithium Battery Power Module
Are you interested in creating a 18650 Lithium Battery Power-Pack.
I want to make this perfectly clear ""I did not come up with this idea"" "" I Acquired this design from the internet "" I am only sharing this information with you.
Now we are only going to deal with a single 7 cell Module. (You can stack these up to 7 to 10 Modules high.)
But we are only going to make a 7 cell battery power module in this Instructable.
This cell will consist of 9 different items.
You can search eBay / Amazon / and the Internet to find all the parts for the very lowest price, but your going to have to buy in very large quantity's, to get the very best prices.
Step 4: PCB Custom Made Board
This board was custom designed and created at a considerable cost. If you buy in small quantities this board will cost you up to $8.00 or more a piece. As you buy in larger and larger quantities the price drops accordingly. But your order cost rises.
I will provide you links to Amazon to find the parts used. (I do not guarantee that the links will work.) they are some times deleted due to vendor stock depletion's.
Step 5: Parts List

(This item is not be included)
Fuse Holders / and / Fuses
Step 6: Soldering Electronic Connections
I have provided 2 Video's and 2 Photos
Soldering is a skill that anyone that wants to work with electronics should acquire.
It takes time and effort, and a steady hand to solder correctly.
So watch the videos. and practice on a spare perforated board.
Step 7: Assembly
Lay out your parts so you can make sure all parts are present.
Orient the battery boxes so that the + side of the boxes are in alignment to the board. You can look inside of the battery boxes and see there are + sings on the bottom of the box and place it so the plus sign is on the top.
You can see on the PCB board a + sign at the top left corner, this orients the parts correctly. Each battery box will only fit on the board in the correct order, (But unfortunately I photographed it in the wrong position; The three battery box should be first then the four place battery box should be second.)
Step 8: Soldering the Battery Boxes.
Step 8 Once the boxes are oriented correctly flip the board over and prepare to solder them in, Always make sure your soldering iron is HOT and melting solder before you start soldering on the board. Always use rosin-core solder on electronics. And use a wet sponge to clean the tip of your iron off before you solder, a clean tip is a must. Heat up the pad and component together, once it is hot the solder will flow freely.
Step 9: Soldering the Fuse Holder
Step 9 Use some type of clamp to hold the fuse box in the correct orientation on the split solder pad. solder one side, then remove the clamp and make sure it has not moved and solder the second side.
Step 10: Soldering the Header Pin
Step 10 It does not matter on what side of the board you solder the header pin in. Just make sure that once you have decided, you do all the boards the same.
Step 11: Soldering the XT60 Connector
Step 11 Make sure you heat it up properly and apply plenty of solder. this is a big connector.
Step 12: Your Done
Your project should at lest resemble the pictures above.
Step 13: Power Wall
As you can see this is the way a power distribution center should look like.
