changed my battery now with video

[cam1965]

...I just got the battery. Cam, do you know if the installer had to open up the battery pack to get this installed? I'm confused about the fact that there is only that one external connector on the battery. Or is that a temp sensor or something?

It's visible in your video too, but looks like the texts of the battery are a bit...crumpled? Just wondering if the battery pack's has to be opened (carefully) to get direct access to the terminals (and for replacing the BMS).

Hi Zarhan.
The BMS is from the original battery. It was soldered onto  the replacement battery. I didn´t use the BMS from the replacement cameron battery.

Ok, found a video of a phone that uses the same type of battery that your replacement - natively. So looks like, that "single" connector actually has all the terminals required in it.

Astro probably does not use same connector (or does it?!), so opening up the battery is most likely needed. But I'll hold off opening the phone until the Astro battery performance has really gone down enough to make it unusable as a daily driver...

Yes, the bms was removed from the replacement cameron sino  battery. I soldered the BMS from the original astro battery onto the replacement battery

Ok, thanks for confirming. I guess once you remove some of the covers you can see all three terminals (or four?) and then can solder the Astro BMS in there.

With that in mind, I'll wait for the Astro battery to degrade a bit more before (e.g. where it no longer holds even a half-a-day charge), meaning that the battery replacement is mandatory to keep the device usable as a daily driver, in case I break things.

OK. Good luck. Only another link ( But for gemini and cosmo ). In this case it is not necessary to remove the BMS from the replacement battery. Check the polarity befory connecting. https://electronicsera.eu/2024/01/04/planetbatteries/ . I have changed my battery in gemini for this Hsabat battery ( https://pt.aliexpress.com/item/1005007976621754.html?spm=a2g0o.order_list.order_list_main.5.295fcaa4HQTq2Y&gatewayAdapt=glo2bra ) . The battery cable must be twisted to put the battery in place.

Ok, one last thing - does the Astro battery have three or four terminals once you open it up? Does it have a data terminal for battery status? Or just +, - and temp?

If it has four, are you getting accurate indications on battery capacity (SoC, percentage)?

I really don´t know.
I left the astro to a technician sometimes ago to solder the battery   and don´t remember.
Maybe searching in google you can find the answer. I only know about gemini and cosmo batteries that I have oppened recently. They have in it the marks ID, +, - and T. Maybe the battery astro is similar.But I really don´t know. I will try to attach a photo to  a battery terminal similar to gemini, but I think this forum as I said before are not letting me to attach photos.
Confirmed this ( The attachments upload directory is not writable. Your attachment or avatar cannot be saved. )

I guess the flexible flat cable has three conductors: minus, plus, and NTC. The NTC is probably on the BMS board, connected to the minus and NTC conductors. Probably, the NTC is a 10 kΩ one.

That is, there are two wires between the battery proper and the BMS board, and three wires between the BMS board and the battery connector.

I assume that the right tool is a soldering iron, not a spot welder. You need a spot welder for round cells, but not for Lipo cells.

Okay, I did it, I replaced the battery of one of my Astro Slides. Thanks for pointing us to a suitable battery! I used a BL-N3150Z:
- keep away all metal parts (tools, jewellery etc) in order to avoid shorts
- open the device with a suitable opening tool (plectrum) as described by cam1965
- remove a lot of screws (those holding down the battery and the battery connector). There seem to be two types of screws (at least two different colors)
- don't forget to put away the screw driver in order to avoid shorts
- unplug the battery connector from the device
- remove the battery along with its frame
- measure and remember the polarity at the battery connector (IIRC, the side far from the battery is plus) without causing a short (measure that the outside of the connector)
- carefully pull the battery from its frame (trying hard not to bend it) and carefully pull the flat flex cable through the opening in the frame
- unwrap the tape (kapton and otherwise) wrapped around the battery protection board (BPB)
- desolder from the BPB the sheet metal that connects the battery to its BPB. Avoid tearing the sheet metal
- remove the outer black cover of the replacement battery (the one which says that warranty is void if label is removed)
- unwrap the tape (kapton and otherwise) wrapped around the battery protection board (BPB) of the replacement battery
- measure the polarity of the conductors of the replacement battery and mark the plus and minus conductors of the replacement battery as such (or remember what's what)
- desolder from the BPB the sheet metal conductor that connects the new battery to its BPB. Try hard to avoid tearing the sheet metal
- insulate the NTC on the Astro Slide BPB (ie, the component at the center) with multiple layers of kapton tape. Unfortunately, the distance between the conductors of the replacement battery is smaller than that distance of the conductors of the Astro Slide battery, making the plus conductor of the replacement battery touch the NTC which is connected to ground. A short must be avoided here by all means
- fold the plus conductor of the replacement battery twice to form a Z such that the two connectors can be soldered to the B+ (plus) and B- (minus) pads of the Astro Slide BPB, respectively
- you might want to connect the flat flex cable to the device to see where the connectors have to be soldered onto the BPB such that the flat flex cable doesn't bend, but avoid letting the battery conductors touch anything
- solder the plus conductor of the new battery to B+ and the minus conductor of the replacement battery to B- of the BPB
- wrap the BPB along with a bit of the battery in multiple layers of kapton tape
- if you're paranoid (like me), measure the voltage at the connector and check for correct polarity as noted above
- put the new battery into the Astro Slide and connect the battery connector to the Astro Slide (do not yet put in any screws -- you'll want to be able to quickly remove the connector if there's magic smoke)
- try turning on the device. Continue if successful. Otherwise, don't blame me
- somehow mark how the frame has to be put onto the battery such that the battery will have the position it now has (ie, without bending the flat flex cable)
- unplug the battery from the device
- carefully put the flat flex cable through the opening of the frame
- put the frame onto the battery as marked above (such that the flat flex cable won't bend). The adhesive tape still sticks to the frame rather than the old battery, at least it did for me. If not, use new double-sided adhesive tape rather than trying to pull it from the old battery
- put the battery with frame into the device and plug the connector into the device
- put back all the screws
- test
- snap on the case

Sorry, no pics as I thought that Astro Slide was my only working camera (I forgot about my second Astro Slide). Perhaps next time, for the other device.
