Description
This auction is for 20 each high current, dual beam, battery spring contacts, which is enough to build one industrial strength DKblock clamp board or one-half of the entire wireless no-weld BMS block. 

This spring contact is made to replace the welding necessary to build packs with 18650 and 2170 cells. If you need higher currents than 8A continuous or 15A for 10 sec, then you might want to consider welding. For reusing those older, welded, shrink wrapped packs that still have usable capacity, those cells can be repurposed into capable battery packs using the DKblock system and these contacts.

You will not find this contact in any catalog for any other company in the world, unless it's a copy of this DKblock part. It was specifically designed using the latest science in materials and engineering, to be the highest performing battery contact for the price. It will allow you to build battery packs without welding a single cell, and it has the highest current rating of any spring contact it's size, on the market (that we know of - please let me know if I'm wrong). It is made of the finest spring contact material (beryllium copper) on the planet, and 100% immersion gold plated over nickel for ease of soldering, corrosion resistance, and improved conductance. It can be hand soldered or machine reflow soldered to your PCB, and the design of the wide base of the part allows it to not move around pre-soldering, making the boards easier to handle. While the parts are designed to be PCB mounted, they could just as well be used with wires soldered for conductors in a custom application. Please note the specifications on the drawing and make sure it fits your application, the large surface area and dual beam allows the contact to fit many different types of battery cells.

Note that the only thing being offered is spring contacts, not the plastic cell holder, or PCB's, battery packs, or battery cells shown in the picture, that picture is only used to show how the hardware all looks like together. Also please understand that the documents for this part are open source and you are welcome to build your own. But make sure you work with someone who has either built very similar parts, or has an extremely good knowledge of high current, low impedance materials contacts science, so that you end up getting high quality parts. 

Please contact me for volume purchases. I do have good deals on 1k or more pieces...

The complete design and build details are available on github at https://github.com/offgridsystems/Documents/blob/master/DKblock%20assembly%20sheet%20OSHW%20V28OCT18.pdf

Please see my other ebay auctions at for the cell holders and other PCB's to build your own DKblocks, search "dkblock". Lithium-ion cells can be obtained online from trusted sources, see my github for some hints on cell selection.
