Are you sure about your claim that ALL batteries charge simultaneously? According to this screenshot, only two pairs of batteries are charging. Note the arrows pointing to 0.0A. 0.0A means that these batteries are NOT charging.



And it's clear that the charger is charging the batteries that are the most drained first (note the capacities of each battery). Most charger algorithms charge the batteries that are least drained first because they charge quicker. This is so the pilot can keep flying as much as possible. As it stands, this charger is going to make the pilot wait at least 55 minutes before he can fly.

I imagine as the batteries become more charged (and amperage demands drop), it's possible that *eventually* all 8 batteries might start charging simultaneously. But honestly, that is not the same thing as charging all 8 batteries simultaneously ALL the time. I have a TB48 charger that truly does charge 6 batteries simultaneously regardless of their remaining capacities.

This looks like a great charger, but you might want to check your claims.

Also, you didn't list a price.

I am positive it charges all 8 simultaneously. Also, I forgot to list a price, that,s on me. $900.

No you didn't anything I forgot to list a price. $900,

I am positive it charges all 8 simultaneously.

The photos you provided doesn't flush that out. I think I did a good job of explaining the evidence. You should make an equal effort to refute the evidence instead of just dismissing it.

Why is it that people think it is up to someone else to prove their doubts? He made a statement which IS true and you doubt his claim based on your guesses about a screenshot.

This is straight from DJI:” With efficient, intelligent management, the DJI Battery Station ensures that shooting equipment is always ready to use. The Battery Station can charge up to eight TB50 batteries simultaneously.”

Why is it that people think it is up to someone else to prove their doubts?

Because that's the way life works. @mediafriend made an assertion. I refuted that assertion. So, YES, it's incumbent on him to make a counterargument. If you or he are unable, incapable or unwilling to make a counterargument, then my point stands that the charger does NOT charge 8 batteries simultaneously. Your choice is to either concede or refute. If you choose to dismiss, well then you lose the argument. Very simple. Common sense.

He made a statement which IS true and you doubt his claim based on your guesses about a screenshot.

Guesses? LOL...you're kidding, right? CLEARLY, you lack understanding of how electricity works. ZERO AMPS means NO CHARGING. Period. It's not a "guess." I suggest you Google "Ohm's Law."

This is straight from DJI:” With efficient, intelligent management, the DJI Battery Station ensures that shooting equipment is always ready to use. The Battery Station can charge up to eight TB50 batteries simultaneously.”

Ahhhhh....The favorite hyperbolic catch phrase of all time; "Up to." This means that SOMETIMES it charges 8 batteries, which is EXACTLY what I said. It's like when your local Internet company advertises "downloads UP TO 500Mbps." This absolutely, 100% does NOT mean that you're going to get 500Mbps downloads. This means that there is a "chance" that "maybe" you will get 500Mbps downloads if you're lucky, and under the right conditions. This charger hyperbole is the exact same thing. You can charge UP TO 8 batteries SOMETIMES under SOME conditions. This is COMPLETELY DIFFERENT from a charger that ALWAYS charges ALL batteries at all times simultaneously.

All that said...

It would be pretty easy to simply plug an ammeter inline with the charger and wall plug and take a reading. 8 batteries x 180 watts (quick charge) = 1440 watts. Divide this by 110 volts = about 13.1 amps. If this device pulls 13+ amps while charging 8 batteries, then just maybe it IS charging 8 batteries all at once. In which case I would question the charger's LED readout. I can say with 100% confidence that, unless something is malfunctioning, according to the screenshot I shared (which was a screenshot of one of the photos the OP posted) that only FOUR batteries are charging.

Discuss.

[Slozukimc]

I would assume, with fear if making a a$$of myself lol, that it starts charging batteries in pairs until all eight are charging and the pic was taken during that time.

Would it be possible for the OP to put eight batteries in the charger and wait a bit to see if that is the case?
You say:
The favorite hyperbolic catch phrase of all time; "Up to." This means that SOMETIMES it charges 8 batteries,……or it could mean that it will charge up to eight depending on how many you have inserted into the charger.

Possibly. But this still doesn't explain why 2 pair are charging and 2 pair are not.

My guess is that the charger in the OP is essentially a 600ish watt unit. Ergo, it's maxed out charging 4 batteries at @ 6.6A, 5.9A, 6.6A and 5.3A (24.4A total). As the 4 batteries become more charged, their demand for amperage will diminish. Then there will be amperage left over for the other 4 batteries, which are essentially already 3/4ths charged. Eventually, amperage will be allocated to the other batteries. Then, eventually you will see all 8 batteries charging @ 3ish Amps (3x8=24). I would bet 20 bux that this charger never exceeds 25A.

Would it be possible for the OP to put eight batteries in the charger and wait a bit to see if that is the case?

That's kind of what I expected him to do when I challenged his assertion. That's would I wouldn't done. And it seems that that is what you would've done, as well.

It could. I agree. But, once again, based on my screenshot (ad nauseum) I don't think it means that. While I disagree with your theory, I am not dismissing it as a possibility. The canary in the cave would be to simply take a photo of all 8 batteries charging (receiving amperage) simultaneously (as you suggested).

Again, from DJI:

“
On a film set, every second counts. To accommodate every critical need, the DJI Battery Station uses three charging modes - Normal, Quick, and Silent - to provide the best power management for every scenario.

In Normal mode, eight connected TB50 Intelligent Batteries can be charged simultaneously, until all batteries are fully charged.

In Quick mode, the four TB50 Intelligent Batteries with the highest battery level in the same group will be charged to 90% in just 35 minutes, making it a useful option for urgent use.

In Silent mode, charging speed is lowered to provide a quieter process for evening charges or when limited noise is permitted on set.”

Very well. Then explain why only 4 batteries are charging in the OP's photo.

Notice how vague the DJI nomenclature is regarding "Silent mode" with a dismal description of "charging speed is lowered." We can only speculate that *maybe* the charger is in Silent Mode. And we can further speculate that *maybe* "charging speed is lowered" means that it only charges @ 25ish amps and sets priority for batteries that are the most discharged (which is the exact opposite of what any drone operator would want). Clearly, the photo is showing the charger doing the exact opposite of that. But maybe that is what "Silent Mode" does. We don't know because DJI hasn't told us.

It's unfortunate that we have to guess. DJI has never been good about documentation (especially regarding firmware updates). They seem to be vague on purpose - afraid that full understanding (disclosure) of said product and/or firmware will steer customers away from said product.

Unfortunately, at this point, only the OP can lend clarification to this conundrum.

I'm interested in your charger. But with all due respect, I need to a see a photo of it charging all 8 batteries at once, because that is exactly what I will need on the job site.

I would have to guess that the charger was in quick mode and only charging four but as you stated without clarification it is just a guess.
