Canon BG-E5 18650 Li-ion adapter =========================== I have a BG-E5 battery pack Suitable for Canon EOS 1000D, 450D, 500D, Kiss F, X2, Rebel T1i, Xsi. compatible grip BG-E5, BP-450D,CS-BGE5 Maybe you will be interested Out of the box, it works with AA batteries, or with 2 LP-E5 batteries. I am not satisfied with the capacity and quality of LP-E5 batteries available to me. Therefore, I make 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, and at a charge of 80 percent, the electronics of the camera turn off the power, without a boost converter this scheme does not make sense) There are 2 revisions in the archive: 1 Open version: --------------------------------------------- Printed, tried, and rejected (white 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 very good material for something durable :) I redrawn and printed a model of white PETG, 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 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, take 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 :) + were corrected deficiencies with the contact 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
