This is my first post here. We have designed a new product that completely does away with the need to spot weld or solder batteries. Its a one of a kind product that’s patented and extensively tested. We are from VRUZEND, part of Ruzen Inc.
The kit offers a level of quality, flexibility and reliability not found elsewhere. All one needs to do is place the cells in the caps provided and make the connections.

The video is in detail and shows how the kit can be utilized to make the whole process of making a battery pack simple and hassle free.
The part list is as follows
1. 104 Battery terminal caps with the internal contact pre assembled. (At least 104. We make sure that every pack has a few extra)
2. 135 bus bars
4. 6 U clamp terminal strips (To make the positive and negative connections)
5. 104 nuts (to secure the connections.At least 104. We make sure that every pack has a few extra))
6. 6 zip ties/cable ties (to further secure the pack once you are done making it)

http://www.vruzend.com is a one stop battery shop. Apart from the kit a lot of other accessories too can be sourced directly from there. USA and North American customers in general can purchase directly from http://www.vruzend.com. Other international clients can fill out the order form at http://vruzend.com/international-orders/
The FAQ section at http://vruzend.com/faq/ will be of great help just in case you have some doubts in mind. If its not answered in the FAQ section you can always contact us.
We ship across the globe and offer multiple shipping options.
We have shipping warehouses in USA, India, Netherlands (https://eu.nkon.nl/vruzend-diy-battery-kit.html ) and UK(https://www.ebay.co.uk/itm/Vruzend-DIY- ... 2856380838).
The quality of the material used is top notch and unparalleled. We are constantly improving and evolving. We give great importance to customer feedback's and make sure to incorporate the recommended changes.
The bus bars are 8mm broad 0.5mm thick made of high grade SS. They have handled currents up to 3.5AH with ease. Have tested them with LG HE2, Samsung 25R and the likes.The cap legs are longer than the bolt ends sticking out from the cap. So there is sufficient insulation.
There is a reason behind using SS over other metals. SS apart from being low on cost offers a kind of strength Copper,Brass,Nickle and carbon steel (CS) do not. This thing has been under R&D since December 2015.

Some of the tips I would like to give you before hand are
To help make your battery building process go as smoothly as possible, a complete set of instructions for working with the Vruzend battery building kit is available in the Tech Center on our website (http://vruzend.com/tech-center/). For now though, here is an abbreviated set of instructions to get you started and familiarize yourself with the Vruzend system.
1) Start by planning out your battery. Drawing out both sides of your battery on paper first can help make the building process easier.
2) Begin by making columns of caps by sliding caps together with the dovetails and sockets oriented in the same direction. For example, for a 10s5p (10 cells in series and 5 cells in parallel) battery, you’ll make 20 sets of 5 cell columns, enough for the tops and bottoms of 10 columns.
3) Start pressing your cells into the caps in one column. You can start by simply using your hands. Then place the second column on the other side of the cells and align it so all the cells are straight. Ensure that the dovetails in the top set of caps are facing the opposite direction in relation to the bottom caps (as demonstrated here: https://youtu.be/9Pxq4Au5iuc?t=4m57s) It is important to ensure that the cells don’t enter the caps crooked.
4) At this point, the easiest method to compress the caps onto the cells is the clamp method, where the cells are clamped between two pieces of wood to distribute the force of the clamps. Once the distance from one end of the caps to the opposite cap is approximately 90 mm, you’re done compressing! One winter assembly tip: cold weather can make it more difficult to slide your cells into the caps. The caps have a slightly conical cavity to accommodate the variation in diameter of different brands of 18650s. Cold weather can make the caps’ cavity contract slightly smaller, making it very tight to press a cell in. We recommend keeping your caps at room temperature during assembly, of at least 70-75°F or 20-25°C. If you live in a cold area, consider leaving them near the heater before assembly to make the cell insertion process go smoother.
5) Once you have created all of your columns, you should check to confirm that you have proper connection with the terminals by measuring the voltage of the threaded cap terminals. If you can read your cell’s voltage, then the terminal is in place.
6) Next, connect your columns together, as demonstrated here: https://youtu.be/9Pxq4Au5iuc?t=6m37s
7) Now you can make your busbar connections. Double check your planned battery layout that you designed in Step 1, then place your busbars on the threaded terminals according to your battery layout. Be very careful to not misplace your busbars, as you could cause a short circuit by touching the wrong battery terminals together. If you see a spark when you lay down a busbar, this is the wrong location for that busbar!
Add your nuts and tighten them down on top of the busbars using a 5.5 mm socket driver. At this point, you can also add any BMS or balance wires https://www.youtube.com/watch?v=m4DGDkwFr54, as well as your charge and discharge wires. The smaller wires can either be wrapped around the threaded post or just clamped under the busbars. The discharge and charge wires should use the included brass wire clamps, either by soldering them or clamping them in place.We have a lot of exciting stuff coming up and will keep you posted.
Thanks!
Looking forward to it !
