Samsung Gear 360 2016 Battery DIY
Description
Do you have Samsung Gear 360 camera and no battery? Or maybe your battery is dead? Well then, this project may interest you. If you try to search for a battery for this thing, you will soon realize it's almost impossible to buy one. Maybe if you are lucky you can find some on secondhand market, factory sealed and never opened batteries from year 2016. Even then you have no gurantee it will work and have decent capacity, because of course battery degradation happens. And sometimes you can find them online from 3rd party manufacturers, but most of them are also old and/or selling for absurd prices. DISCLAIMER: I'm no CAD master and more like casual tinkerer. Design might not be perfect and is probably not the safest one, because we are dealing with Li-po baterries. Because of that make and use the battery at your own risk and know what you are doing. Improperly handled li-po batteries could be fire and explosion hazard. PARTS: So, here we are. What will you need to DIY your own battery? - 3D printer and any filament, tested on PLA and PETG. Around 2-3g of filament is needed for the battery. - 603035 Li-po battery - available on Aliexpress, you can just search for 603035 Li-po and order any that ships to your adress. I have bought 4pcs for 33 PLN (~8USD). - 3PIN Gold battery terminal - available on Aliexpress. To find the exact one you can google search "BC-20-3PD160" and image search on Aliexpress for the exact one. I have bought 5pcs for 10PLN (~2,50USD). - Kapton tape to secure battery in place. I wanted to design some kind of cover, but it turns out batteries are in some spots not 35mm, but 37,5mm and I didn't really want to bend corners and terminals to make it fit. I just decided to use some kapton tape, as it will sit inside the camera anyway. COST: Okay, that's all. How much for one battery? * filament - 0,12PLN (0,03USD) * battery - 8,25PLN (2,04USD) * terminal - 2PLN (0,50USD) Comes down to 10,37PLN so around 2,57USD. That's pretty cheap if you ask me, but prices may vary in your country. ASSEMBLY: Everything is pretty straightforward. I designed the battery to hold terminals in place using press fit and friction, but you can glue them if you like. Just be carefull to not glue everything around. Also i preffer to have the ability to dissasemble the battery if needed, maybve I'll come up with better design and I'll need to swap the cell to new print, who knows. Remember to solder wires before putting the terminals in place, as you can melt the plastic doing it the other way around. Gold terminals facing you, and with solder points at the bottom is from the left: MINUS, THERMISTOR, PLUS. Thermistor, huh? But we have just two wires, what's up with that? IMPORTANT: Li-po and Li-ion cells should not be used in too cold and too hot environment. That's why manufacturers are implementing safety mechanisms to avoid fire and explosion risk. One of them is knowing what temperature battery is currently at, to not power on the device or halt charging. In removable batteries it is done by third pin which changes value (mostly resistance, but sometimes capacitance) according to the temperature. As I do not have the original battery, I cannot really tell which method is used (probably thermistor) and what value should be the part needed. Without this part, the battery might be at higher risk of fire or explosion, as the camera have no way of monitoring it's temperature. Without thermistor connected camera will power up, but won't charge! Luckily there is an easy workaround - bridge the middle pin with battery minus. This will trick the camera into thinking that there is a thermistor and everything is fine. USE THIS AT YOUR OWN RISK. If the battery overheats during charging, especially if you are charging and recording during hot day, this may lead to unwanted effects like fire or explosion. With that out of the way, let's get back to the assembly. After soldering wires, slide terminals into place, push the battery inside the casing and secure it with the tape. I reccomend kapton tape, as it is intented for use with high temperatures and li-po batteries. Battery enclosure dimensions are ok, but depending on your printer you might find it a little bit too big. You can sand down the edges if you have some material overflow there, this might help. For easier removal battery has little cutouts to make it easier to grab using nails. I hope this model helps someone and will contribute to reducing e-waste, as we have it too much on our planet. If you have any suggestions or design reques, please comment.
