Router Battery Backup

R13... said:
The bigger the battery the better. I bought one of the smaller battery ones about 18 months back and the battery went from about 6 hours back then to around 3 hours now. Means I can't ride through a 4 hour slot (which is usually around 4hrs 15min)

Did it have LiFePO4?

I don’t think those have LFP but rather the lucky packet cheap Chinese NMC cells.

So make sure your new one has the betterer LFP cells.

It's just 2x LED strips, probably around 40W. The Ratel should be able to power them for around 4 hours if I calculated correctly.

40W may be more than what the routers were drawing is all I'm mentioning.

I have a bench power supply. I use it when I design signs for shops and stuff. Helps me figure out where the LEDs go also how much power it draws.

That is the point Actually, if you have access to a pench power supply you will be able to ajust it to 12V and then power your router with it. The amp reading will tell you how much amps the router is actively drawing. With that reading you can accurately calculate how long a router battery backup will last. I know not everyone has access ot something like this but In found a reasonable one. Also it is really nice if you work on electronics in general. It can also charge batteries for the most part.

I encluded a link to a really nice one. Minedoesn't have the USB function.


SUNSHINE - Intelligent DC Stabilized Power Supply
 
Hey guys,

I have a Ratel 860P. Last night I think the storm got to it, and now it won't charge. It will turn on and provide power to my router and ONT though, so I think part of the board is still functioning. But this no charging story makes it pretty useless.

Anyone managed to source a replacement board? Or is the answer what I think it is, and just replace the whole thing?

Maybe its just the power supply? Try one from the router?

If you open it, just have a look at the component that blew. And replace it.
It is usauly a R4 part and 15min of your time with a soldiring gun

Thanks. Well that was the same idea I had but the problematic component is not obvious. Everything looks fine. I have come to accept that its time has come. She served me well

I have 2 of these. One for my router and one for my fibre modem. No issues.

A heads up, my router UPS packed up, wouldn't power on and when I open it up I discovered the battery pack had become unbalanced, it had a pack of 4 cells with 2 banks of 2 parallel cells, one bank was at 2.5V. Jumpered just that bank to a Nitecore Li-ion charger and gave it a full charge and the UPS is back up and running.

Something to keep in mind because an unbalanced battery pack will also reduce the UPS runtime because the unbalanced cells not getting a full charge will pull the whole pack voltage down and trigger the cut-off far earlier than it should.

You would think they would have a balancer.

What make and model?

It did appear to have a balancer wire on the pack but who knows what system it’s actually running.

Linkqnet, 99% of these mini UPS look to be rebranded products of somewhat dubious origin, you can find dozens of identical products under different brands on Takealot.
