VRUZEND – Battery building made simple!

No more spot welding… and no more soldering either!
Just snap together the VRUZEND bricks and then bolt together your connections. It’s really that simple!
Lithium battery packs for everything from electric bicycles and skateboards to home energy storage and electric vehicles are crazy-expensive, right?!
Why is that? It’s because making lithium battery packs used to require special tools and highly skilled workers to use them. But not anymore!
VRUZEND lithium battery building kits were designed to solve that problem. The plastic end caps slip tightly over the end of the most common lithium battery cell format, the 18650 cell. They can be snapped together like Lego™ bricks to create any size battery.
Then simply bolt the cells together using the supplied connectors and you’ve got yourself a custom lithium battery pack for a fraction of the price of buying an off-the-shelf lithium battery pack.

Spot welders are expensive. The good ones cost more than the price of most lithium batteries! Cheap ones are dangerous and prone to breaking when you need them most. Plus, spot welded packs can’t be opened up to replace a single cell if it ever goes bad. VRUZEND kits can!
With VRUZEND’s innovative DIY battery kits, you simply work with your hands! Snap together the terminal caps, add the connective bars and then tighten the nuts (ok, so you need a socket driver for the nuts, you got us… But it’s mostly tool free!)

VRUZEND battery kits are designed so that they can be opened up whenever you need if you ever want to expand your battery or replace a cell. Just pull the kit apart and the batteries are easily accessible.

The plastic end caps work like spring washers or nylock nuts by compressing under the force of the nuts on either end. This provides a counter force to the nut and helps prevent the nuts from loosening even in transportation applications that are prone to vibrations.
If you’re still worried about vibration loosening of the nuts though, there are other options as well. Loctite or other thread-locking compounds can be added to the nuts, or just a good old fashioned drop of hot glue on the nut will keep it from moving until you’re ready to remove it.

The VRUZEND battery building kits come with safety post on the ends of every cap to keep your battery terminals and conducting bars lifted off of your work surface while you’re building your battery. This helps prevent accidental short circuits during battery assembly.
VRUZEND kits can be used to build batteries of nearly any size and shape. You are no longer limited to a small set of battery sizes. You can build the exact battery voltage and amp hour capacity that you need. And if you want extreme capacity, you can build a few battery packs and connect them in parallel, side by side, to create super high capacity batteries that are great for home energy storage.
The VRUZEND battery building kit really is the best way to build a custom lithium battery from 18650 cells. But don’t take our word for it, try it today!


Instructions:

Congratulations on purchasing your new Vruzend battery building kit! We are confident that you’re one your way to building an awesome DIY battery!

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!

8) 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, 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.

And that’s it! Enjoy building your battery and remember to be safe!
