Re: Circuit Gem battery

Re: Circuit Gem battery
Just to contribute:
This is the battery I used: 750mah. Shipped from within the US.

I only removed the hdmi and two usb connectors. And still used L/R buttons

Re: Circuit Gem battery
Here you go, a few pics as a reference.
An image of the device open. note the orientation of the battery. Especially the fact that the top of the battery is facing the top if the case, since the top back case is slightly curved and the top of the battery with the charge protection is thinner.
An image of the pi zero w board from the side. You can see at the left side the bulky power regulator and below it the bulky Capacitor.
An image of the battery on top of the pi zero w as it sits inside the case when closed. You will notice that it sits just above the large capacitor and well above the Power regulator and CSI connector.
A clear image of the battery.
The inside of the back case. Everything scraped off. Since the CR2032 battery cover is slightly thinner than the rest of the case I put a light amount of hot glue the carefully smeared it all over to hold the cover in place but not add thickness to the case.
The outside of the back cover. The screw there is the original screw just completely clipped and glued in place with super glue.

Re: Circuit Gem battery
This really helps, thanks! I'm using the same battery so it's great to know that the HDMI and micro USB connectors have to come off.
Do you have any special tips to share about how you removed those connectors? The holes look a bit small for a solder sucker, so I'm assuming wick needs to be used? And do you remember what temperature you set your soldering iron to?

Re: Circuit Gem battery
Actually if you take a look at the first pic you'll notice that connector pads are missing. This is because I do need to you the pads after taking them off. So, I just took the easy way out. with a flush cutter I cut the sides of the USB and HDMI connectors and just pulled them off with a pair of pliers. That's why the pads came off as well. I do have a hot air gun for these type of operations, but in this case, why botherpigcheddars wrote: ↑Sun Mar 17, 2019 4:01 pmThis really helps, thanks!

Re: Circuit Gem battery
That makes sense.
Thank you for posting these pictures, that's a really nice clean job you've done there. I'll definitely be using them as reference for my build!

Re: Circuit Gem battery
The HDMI connector has some fine pitch SMT components near it which I was worried about buggering them up by unsoldering them:pigcheddars wrote: ↑Sun Mar 17, 2019 4:01 pmThis really helps, thanks!

Re: Circuit Gem battery
FWIW, I've tried a uxcell 600mAh 503040 that was previously available in the US via Prime. I had to thin out the back side of the case to get it to fit correctly. Seems like a 5mm thick battery is pushing it a bit too far. The Adafruit 500mAH 503035 was also a bit of a squeeze.
I finally received today from China a Liter 482953 850mAH @diko_d already confirmed working and also a Liter 452855 1000mAH battery. I'll try the larger battery out this week and see if it's too long.
