in our household i have a saying.. "it's already 'effed up, i cant make it worse!" if its broke you have nothing to lose, nice video.. its tuff to buy factory smoke anymore!

@TheSmokinApe Год назад

Lol, agreed. Thanks for watching 👍

One big, nice thing about How-To vids is that 'we' see that 'it' is a problem for others, too; and, that it is fixable. Dang, sigh of relief. I thought I'd do a little switch of technique and just cut and re-solder the connecting wires and not solder on the board itself. Thanks for the vid.

@TheSmokinApe Год назад

Thanks Zingo, glad you got it sorted 👍

To be safer, solder a resistor to the battery when disconnected from the unit and wait until the battery is fully discharged, then remove it You are going to discard it anyway and it is then safe for the recycling plant to handle. I am not even going to mention the placement of the wires on the soldering pads neither the dabbing several times with the soldering iron to risk cold soldier joints. 😄 Just get a course on how to solder. Else a good video. Thank you.

Good transplant. Janky tape has fixed so many things in my life.

Janky tape is the best tape...

Well done Ape! Glad you didn't have to battle the "smoke".

@TheSmokinApe Год назад

Haha, thanks for watching Dean 👍

Of course it worked! I didn't have a single doubt!

@TheSmokinApe Год назад

LOL, I was expecting some goofy curve ball out of left field!

I replaced both the sma connections, they were getting worn out. If you try it, i recomend chopping them up with a dremal first, much easier and less heat input to remove the 5 pins individually then the whole connector. I almost ripped off the traces

@TheSmokinApe Год назад

That’s a good tip 👍

@RadioJimProductions 6 месяцев назад

Even better, get pair of male-to-female SMA adapters to use as connector savers. Leave them permanently attached and replace them when they get worn out.

@FEPLabsRadio Год назад

That looks like a LiPo battery. Good work!

@TheSmokinApe Год назад

Thanks FEP 👍

@Tump2010 Год назад

Disappointed that there was no smoke... 😀 You should have discharged the battery first to make it safer. Good video

@TheSmokinApe Год назад

Everyone likes the smoke show!

Nice easy job!

Yes it was!

That's a solder bridge you don't want to make. Nice fix.

@TheSmokinApe Год назад

LOL, right!

Almost played into the Hollwood action movie trope, with the careful wire cutting there. 😃 Directed by Michael Bay?

Me too. Thanks for watching BA 👍

Seeing the magic smoke come out is always entertaining...when it's someone else's equipment.😊

@TheSmokinApe Год назад

Right, lol 👍

Solder flux is you friend...you need to use it next time. 🙃

Those batteries look similar to one of the first drones I bought years back. I probably need to go back and check the batteries to make sure they are not bloated. I know I hand a couple of batteries for one of my Nikon cameras bloat. it made it a pain to get it out of the camera. Now I keep them out unless I am using the camera. 73

@TheSmokinApe Год назад

Bloating batteries sucks...

@KS0JD Год назад

@@TheSmokinApe Better to bloat than blow up or catch fire ;-) 73

@Ressy66 Год назад

trick: isopropyl alcohol, and a small syringe, dispense tiny squirts at a time - dissolves the glue, battery just falls away :)

@TheSmokinApe Год назад

That's a good tip!

@kevinkc3onohelijeepworld953 Год назад

Reason it puffed is from leaving it stored at full charge. I think the nano vna guy could write sum code to auto balance to storage voltage 3.7v. Leaving it full makes the dendrites form and crystallize on the anode and short across to cathode internally 😉

@kevinkc3onohelijeepworld953 Год назад

Ps lots of info on lipo batts are battery university online

@TheSmokinApe Год назад

That could have been it...

@kevinkc3onohelijeepworld953 Год назад

@@TheSmokinApe most common failure of lipo so much stored energy it does t like not being used. Maybe we can convince the software guy to write a few more lines of code to help preserve batt life ?

@joeshmoe7899 8 месяцев назад

But, doesn't voltage decrease over time while in storage?

@RadioJimProductions 6 месяцев назад

If the unit is going to be stored for some time the battery should be discharged to 50% and disconnected. There is a small but finite current drain even when the VNA is switched off. Lithium based batteries do not like to be completely drained and this will damage them. Ask anyone who has tossed their iPod in a drawer for a few months and later found the battery to have failed. if you only use it infrequently and you don't want to go to the trouble to disconnect the battery then the unit should be periodically maintenance charged to keep the battery from draining completely.

@subramanianr7206 Год назад

My original one had the same issue and I replaced it with a larger but thin enough battery; it is working well. You could have done the soldering of the wire tips to pads on the PCB bit more elegantly. De VU2RZA
