Canon BG-E5 18650 Li-ion adapter

Canon BG-E5 18650 Li-ion adapter ================================================ I have a Canon EOS camera accessory that fits perfectly with my camera's battery pack. Suitable for Canon EOS 1000D, 450D, 500D, Kiss F, X2, Rebel T1i, Xsi. It also works well with compatible grip BG-E5, BP-450D, CS-BGE5. Maybe you'll be interested in this adapter that I've made to work with more common Li-ion 18650 batteries instead of the LP-E5 batteries that came with my camera. Out of the box, it works with AA batteries or with two LP-E5 batteries. However, I wasn't satisfied with the capacity and quality of LP-E5 batteries available to me, so I created an adapter for more common Li-ion 18650 batteries. Physically, a pair of lifepo4 22650 is placed into the grip, but the camera only works with them when fully charged. At a charge of 80 percent, the electronics of the camera turn off the power without a boost converter, making this scheme impractical. There are two revisions in the archive: 1. Open Version --------------------------------------------- Printed, tried, and rejected (as shown on the photo). I made this adapter before acquiring a 3D printer from polymer clay and old parts. In principle, it turned out to be quite comfortable and worked for about 2 years, but clay is not a good material for something durable. I redrawn and printed a model of white PETG with nozzle 0.4, layer 0.15. Pros: + I have a battery with a fair capacity of 3.7ah, which is about 3,500 shots at 500D - this is really two times more than 2 batteries from Canon, and they are practically not discharged during long-term storage. + Easy to replace batteries. Cons: - With sharp shocks, batteries may lose contact due to this, the camera may start to behave strangely, it is treated only by taking out the battery for 2-3 minutes... - The printed opening mechanism works quite tightly, in gloves it is difficult to open - The small elements are hard to print :( redone several times and print with nozzle 0.2 and a layer of 0.1 mm, if you have more experience with the printer this may not be a problem :) - I use only contacts plus and minus, the camera defines the adapter as batteries, without increasing the flash charging speed as with two original batteries 2. New Version ------------------- Printed of a shock-durable blue HIPS, taking into account the threaded rod it does not make much sense, but I did it!! Pros: + Survives falling from the table without expanding the batteries :)) + Deficiencies with contact were corrected from the first version + Now in the scheme are quite strong springs, nuts and m3 stud for durability, while this is also the main disadvantage :) + In the future, I plan to glue the case tightly, but have not yet decided on a balancing scheme and method of charging. Perhaps the body will change a little. Cons: - M3 nuts must be unscrewed to charge the batteries in a separate device, but given their capacity, this happens 1-2 times a month - I used ready-made caps for the supplied adapters, so now I have only two batteries - Old adapter too :)) - +/- I have not tested the compatibility of the cover from the first version with the flange from the second, the fasteners may not match. ---------------- PS: Thanks to a friend for the opportunity to draw all this in solid :) without help, I would still study another 3D editor. .SLDPRT models are attached in the archive
