Router Battery Backup

So its a combination of both temp and watts. Thermistor in pack alone only shuts down the unit if you unplug it or short it out and heat it up.

Thank you very much.

Seems like it's very well designed. I would have guessed that the fan would just stay on pernamently but this feature should help to extend the life of the fan.
 
My garage was flooded last night, and the batteries got wet too. It's a pylontec us3000.
It was in a standing position. Was working but still disconnected the battery.
Water was inside the battery, so stripped it open and it's now drying.
My question is, is the cells inside the battery sealed ? As the water has not actually touched the circuit, will it be safe to use ?
The blue line indicates the water level it was submerged in

I think the reason it was still working is because it was submerged in the "right side", away from the electronics and the wiring connections. Maybe suspending them upright would have been a better idea?

The rubber thingy at the bottom was not allowing the water to drain properly, so put it this way.

Edit :
Yes I wanted to move the battery higher up but the box was costing r7000 and I wanted to add more batteries as well . Lesson learned... will get a make shift bracket in the mean time and hang the batteries higher.

update on this.
It was working just fine. But now I started to notice some weird behavior.
The battery is not ready to charge above 65% and its sitting at that for 2 hours. The charging current is showing as 25A and the charging voltage is 53V, which is 1325 watts it should be drawing from ESKOM but when I check the actual prepaid meter, power output is at 601 watts, this is what my house is currently using and therefore the battery is not using anything.

I dont know what I can do next. I only noticed this yesterday and I dont know how to troubleshoot further.

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.
