Router Battery Backup

Does anyone perhaps have an internal photo of the Huawei B315 Backup Battery Pack hw-li2.6ah-c. My unit flashes red and doesn't charge at all. When I opened the unit up, I found a black broken smd component that is situated right net the B+ connector. Its unmarked and I don't know the value of the broken off component. Any assistance would be greatly appreciated. I have attached an image with the component in question circled...Thank you CM230313-112256001.jpg
 
So I have now setup my one Netogy Mini 14400mAh DC UPS to power my router and ONT (both 12v) and 1gbps switch (9V). Should now be able to handle those 2 consecutive 4 hours LS slots which my desktop UPS could not do because it could not recharge fast enough. The included cables, one with splitter (used for the 2 x 12v devices) , one straight (used for the 9V device) were just enough for my use there.

I want to use the other Netogy for my CCTV system and the included cables would not be enough, where can I get more such cables?

power cables? Honestly they're pretty easy to make.
 
How do I estimate uptime? I'm looking at this for a Huawei B315s-936

For comparison and uptime estimates one can look at how many watt-hours (Wh) they provide and compare that to your device's consumption. If you have a 32Wh UPS and your router draws 10 watts on average you're looking at around 3 hours (real world usage is always a bit below the max capacity and batteries degrade over time too).

Looking at router power supplies can give one some idea of the wattage but these are always specced higher than regular usage - my router and ONT power supplies combined would suggest a draw over 20watts but they really draw under 10 watts combined.

I wouldn't go for the first device you linked, only 22Wh and for the price one of these sorts of units has better battery capacity (32Wh) and more connection options, and if you check Takealot they can sometimes be found for low R500s, plenty of similar units listed there. The second unit you listed is 38Wh and seems better, but more expensive, not sure what battery chemistry it has.

Personally I would look for something with LiFePO4 cells even if it costs a bit more as they will last longer than many of these "lithium ion" (NCM) models and LiFePO4 models are becoming more widely available now.

Check how many watts your Router draws. Then check the Wh rating of the battery...

e.g. the router draws 12W constantly. Then the that time that you would like to run it for, let say 4 hours.

12w x 4 hours = 48Wh. Then look for something with around 20% more capacity than the required capacity to be safe.

Thanks a lot guys. That Elecstor looks good I might go with it.
 
For anyone wondering what the Gizzu 100W looks like inside, I opened mine to double check what batteries it has (box says Lithium-Ion LifePo4 :unsure:).

They're LifePo4 and interestingly, there's a space below it for another battery pack but I don't see any pin outs on the motherboard for another pack:

Just parallel to the existing pack maybe a halo model will come , when we get higher stages hopefully not or not soon at least

You will probably find the bms inside that shrink-wrapping around the battery. It makes for a fun wiring exercise if you need to replace the batteries in future.

Unless the cells are parralel
And the voltage is stepped up from the 3.2v

That would be awesome as all you will find is cells and nothing else

Making expanding the battery
A painless experience

pack voltage?

Thanks for the info. I see they all use the ECO PCB same as the Ratel 860p.

Netogy UPS100-Plus if anyone wondered what's inside.

Looks like the same battery as the Gizzu 100. 4s2p pack and BMS is on the main PCB. If one could some 18650 LiFePo cells for a better price than this > https://www.diyelectronics.co.za/store/li-ion-li-po/3418-rs-pro-18650-32v-1600mah-lifepo4-cell.html you could easily add more capacity there is space for another pack :unsure:

Voltage seems low.
