THE SALE PRICE IS ONLY GOOD UNTIL THE END OF AUGUST OR WHILE SUPPLIES LAST! 
 
This product was initially intended for customers outside the US, but I now offer it to everyone!
The law doesn't allow such large lithium packs to be shipped outside the US using the mail service, and shipping the complete DJI battery kit including the lithium pack using other companies is prohibitively expensive.
 
This listing is for the modified DJI  "head" containing the electronics, all brackets, and straps. All you need to complete it,  it's is a lithium pack. You can buy it in your country, or from China.
The lithium pack should have dimensions of approximately 166mm x 50mm x 65mm, and weigh no more than 1100 - 1200g. It must be a 6S pack, preferably high voltage (22.8V) with a discharge rate of at least 10C. 
To custom make the 3D printed parts, and program its computer, you will need to let me know the battery specifications you will use. You can use a battery with any discharge lead as I will match it accordingly.
 
You will not be able to use this product with many batteries. You cannot just swap the discharged battery for a charged one after every flight. You'll need one per battery, but you could swap a  battery that has become inefficient (after lots of use) for a new one of the same capacity.
 
If you live in the US shipping is free, but if you don't, please contact me for a shipping quote as it varies from country to country, but I found it usually costs between 30 and 40 Dollars.
Feel free to order, and I can invoice you for the shipping fee once it is ready to be shipped. I usually ship all custom orders within just a few days.
 
You'll get everything needed but the battery pack. You'll get the programmed DJI Smart battery "head", all necessary 3d printed brackets, and straps as well as an instruction manual to show you how to connect it, and how to secure it all to your drone.
 
Don't hesitate to contact me should you have any questions.
