2x SOK 206Ah or 4x SOK 100Ah?

Well that will be a problem for me then, because I avoid wireless devices due to severe health issues. I will have to take it up with the manufacturer, because they sold me something they did not advertise. Damn it.

As well, these batteries can be used for various reasons. In some situations, the bluetooth could introduce unwanted radiation interfering with measurements. As well, it introduces an internal load, which may not be needed, nor wanted. All in all, pretty idiotic thing to do, for the manufacturer to introduce the bluetooth into existing product and not even let purchasers know about it in the description of the product.

Quite disappointed.

If you’re avoiding Bluetooth devices for health issues then I have some bad news for you. Whatever device you’re typing your posts on is putting out far more EM radiation than the Bluetooth BMS in those batteries.

Clearly you have not read about how EMF propagates via microwaves and also due to its digital nature is very different to low intensity analog EMR induced from other devices.

No, you don't have bad news for me. My devices are relatively safe and you know precisely zero about my setup.
Instead of being presumptuous, do some actual scientific reading on the subject and you will find that non-ionizing radiation does do harm. It has been proven long ago. I have no interest debating this with you and your assumption that just because something is widely used, it must be safe.

Cheers

No assumptions here. I spent years working in RF. There are plenty of things that are widely used and aren’t safe, but this isn’t one of them.

EMF doesn’t propagate via microwaves, microwaves are a form of EMR, with a frequency between 1 and 1000 GHz. Bluetooth does fall in that range at 2.4 GHz, but only puts out .01 mW to 100 mW. Those BMS modules are transmitting through a steel case, so a lot of that power is lost long before it hits the open air.

There’s also no such thing as “digital” EMF. Electromagnetic waves are analog. Digital just means you’re using arbitrary measurements to decide that a signal stands for a number.

Lastly, I know that nothing I’ve typed here will convince you, and that’s fine. I’m not here to argue with you. You’re free to believe whatever you want and act accordingly. What I’ve said here is for the other people that read this thread so that they don’t get misled.

Ah, you are one of those experts that come in here saving the world from the likes of me so they won't be mislead. Awesome.
I get actually sick from microwave radiation, and I do not need experts like you to tell me that my body really ought to feel good in presence of microwaves.

Working in RF does not mean you are up to date on the scientific literature of EMF biological harm. Just like me driving a car does not make me an expert car mechanic.

The industry has captured the FCC and others and tell them what safety looks like. Not what science actually says about it. Nobody wants to know about this because it is so damn inconvenient. Just because people are not dropping dead does not mean something is safe and there are no long term effects.

Microwaves usually have a carrying base wave oscillating at one frequency and there is another frequency that carries the data, which has the EMF attached to it. That second wave is pulsed, or digital, so yes, there is the aspect of one's body being subjected not to continuous EMF field, but EMF that is on and off, so to speak.

You also forgot that SOK sells a marine type of battery, so your argument about the metal case is null and void.

Finally, so our readers don't confuse your experience in RF with what actually scientists know about RF, here is one prominent scientist that actually studied EMF and biological effects. The video is long; but if you want just a snippet of info and confirmation that what I talk about is not BS, you can watch from the 1:30min mark to about 5:00 mark. In that segment, the video shows how The US Office Of Naval Medical Research issued a warning about EMF/RF being harmful already back in 1971.

That is one of thousands upon thousands of articles and studies from around the world documenting harm from microwaves to all living things.

Solar radiation includes microwaves, and in fact the sun
is the single most harmful thing to all life on this planet.
If you're afraid of bluetooth it's because you're a hypochondriac.

Thanks for the diagnostic doctor. You can keep it.
Perhaps you can go to hospitals and tell all the people whose symptomps you do not have nor understands it's all in their heads too.

Life evolved with the sun's microwave radiation which is tapered by the ozone. When ozone is depleted or there is intense sun radiation that comes through, it can be harmful. But that happens occasionally and for a brief moment. Life did not evolve with pulsed electro magnetic radiation which is on 24/7 and which we keep increasing by adding more devices.

People sensitive to EMF is a recognized and legitimate disability in several countries.

When you bring such childish arguments to the table, you only make an ass out of yourself.

Hey, no problem.
Please explain how "life evolved".

 

[waveride]

This is getting tiresome. I posted evidence to back my claims.You posted vague old and childish claims.
I explained to one of the posters why I did not want bluetooth in the BMS. I am done on this topic with the likes of you.

 

[Aly_Oops]

Not sure, but I thought I saw a picture of a bluetooth module that can be plugged or unpluged. I am testing the new 206 and it doesn't draw much in power. There is info on the draw amount, but forget where I saw it.

 

[waveride]

That is a different type of bms. Namely the Jbd BMS have a pluggable BT. The SOK does not. But I spoke to the manufacturer and got the schematics of the 3 resistors that provide power to the BT and unsoldered them. Problem solved.

 

[Aly_Oops]

Good to know. I haven’t open up mine yet.
