We receive about 200 emails per day from people who are trying to build a lithium-based battery pack, and have run into some sort of problem. As a global seller of BMS units, we often hear complaints that the BMS isn’t working properly.
Well let me tell you something. We test every unit before it leaves our shop so that we can shoot down the idea that the BMS isn’t working properly. We do that for you the builder, and also for us. If you can focus on your build knowing that the BMS isn’t the source of your problem, you are going to find the actual problem much faster than blaming failure on the complicated, mysterious BMS unit.
So here you go: Our notes on how to troubleshoot the bug in your build:
We’ve had too many requests to ignore. We’re bringing back the store here to our home website. Everything will still be available at eBay, but prices here will be a bit lower as we’re not having to pay all the extra listing fees.
Also, we will soon be adding an investment page to track and discuss investment opportunities that we actively invest in. Many of these are publicly traded companies. Just always do your own homework.
We’ve been under an almost overwhelming volume of activity the last month, and it has caused us to retrench a bit from our daily upkeep of the website.
First, we’ve killed our storefront here at Gridvision.net. All sales are going through our eBay and Amazon channel at this point. Dueling inventory code was just not something we have time to write at present. We’ve entered the Global Shipping program of eBay, and we’ve already begun making sales around the globe. Our most active non-continental US areas are Australia, Italy and Puerto Rico. Hawaii has been strong as well. We’ve also entered into a deal with a large US supplier of lithium-based cells, and we’re about to begin offering these at excellent prices through our eBay channel. This will complement our existing manufacturer relationships, and allow us to offer an entire array of chemistries and sizes.
We’ve teamed up to start a new entity that has just now been awarded a Patent Pending on a production process for Graphene Nanoribbons. We are actively looking for a suitable lab environment and partner to prove and refine the manufacturing process. Our new entity is General Graphene Technology, Inc.
Antibiotic-resistant microbes are increasing in strength and in number. The rates of change themselves are also increasing. Society should be worried.
We began researching ultraviolet sterilization methods, and after settling on a wavelength of about 280nm, we had a lab design and produce a prototype array for us. (We have a few extra arrays if you are feeling experimental.)
Our array is driven by 20-28 volts DC, and requires a constant current of 125mA. At the moment, we are driving the array with our favorite DC power supply, but we intend to design a dedicated constant-current LED driver to integrate into the next iteration.
UV-C encompasses wavelengths that tend to be almost completely absorbed by our atmosphere, and that’s a good thing as UV-C can cause cancer, blindness, and other major health issues. It also happens to be perfect for killing microbes.
As we became interested in the technology, we began seeing plenty of small devices for sterilizing small tools such as nail salon equipment. Don’t buy any type of UV-C equipment that you can see into the sterilization chamber. Such devices can hurt you, and are ripe for eventual lawsuits. Our next iteration will include a kill-switch that shuts down the device if it isn’t properly closed (similar to how a microwave oven shuts off if you arbitrarily open the door while it is running).
We are seeing a lot of patent applications in the field, and I expect the area to grow tremendously. We’re going to mount one to a Roomba and let it continuously zap our floors once we finish building a protective/restrictive cover for it….
