Without this -- yes, he's in trouble... 😞 

 

Battle Born's operating company Dragonfly Engergy has experienced a 99% fall in share price over 3 years, its cash reserves will sustain it for about 5 months at its Q1 rate of operating loss and rolled over debt is due to mature next year.

 

The more pertinent question is can BB afford to fund the legal case.

They don't have any choice -- if they don't do it to try and defend their reputation (good luck with that -- IIRC there's already a class action suit against them...) they're *definitely* going bust, if they do they'll only *probably* go bust... 😉 

 

But in the meantime, while they're going down in flames they can still cause Will big legal/financial problems -- which of course will make their reputation even worse... 😉

I agree which is why Google AI reivew of their shares says...

 

Dragonfly Energy (NASDAQ: DFLI) is a high-risk, speculative penny stock. While its proprietary dry electrode battery technology and aggressive growth forecasts attract some optimistic investors, the company's severe lack of profitability, falling revenues, and penny-stock volatility make it an unsuitable investment for conservative portfolios.

 

There is a case to be made for the Federal Government to step in an declare BB is culturally unfit to manufacture a consumer power product, however BB also has a sizeable loyal customer base that remains convinced their premium price BB purchase is technically superior. With the US mid-terms 6 months away there is a political dimention, the Feds shutting down BB would be equivalent to the British Government bankrupting BMW UK and ordering their cars off the road weeks before a General Election.

Let's see how loyal that customer base stays when the stink from their lawsuit against Will Prowse -- and the facts behind it -- spreads around the internet... 😉 

 

I guess it's possible that they're MAGA-style devotees who don't want to hear facts that conflict with their opinions, but I wouldn't be surprised if this all triggers a backlash against BB -- driven by the lesson they haven't learned from Watergate, which is that the cover-up can be much more damaging than the crime... 🙂

I suspect the noise around the class action and now the lawsuit against Will Prowse is already persuading many potential customers that with many other suppliers out there, perhaps Battleborn is one to avoid.

Will is getting online grief from BB fanboys, this dispute is becoming tribal.

I personally imagine BB batteries are purchased by squeeky clean, big salaried urban Democrats voters proud of their virtual signaling low carbon offgrid BB battery.

 

MAGA people are far more likely to build their own LFP battery bank from raw cells to drive their BBQ spit roast motor so they can cook a leg of wild boar they just shot while exercising their second amendment rights.

Oh come on -- MAGA people wouldn't be seen dead anywhere near woke LFP batteries, and they'll probably be using clean wonderful coal on the BBQ... 😉

I suspect well off MAGA people with enormous RVs would be only too likely to fit batteries from a premium-priced American brand, no matter how they fuel their BBQs.

Dragonfly also own Wakespeed so this is also causing consternation to suppliers / installers / users. However, if Dragonfly do come to grief I would see Wakespeed being a division that could be sold off and continue trading under new owners.

Latest news is that BB edited a battery spec sheet one day before filing their legal action, they reduced the max charge rate to below what Will Prowse had tested at.

 

The voluntary army of paralegal researchers has uncovered BB claiming in a YouTube video that their batteries can be charged at 100% nominal AH capacity at the risk of reduced long term life expectancy and the original battery spec sheet, before the devious edit, confirms that Will P tested at their publically stated lower cautious charge rate.

I haven't been keeping up with all the latest news, but understand there are a couple of different data sheets floating about for the BB1275/1275H 75Ah battery. One states 50A max charge current and the other a 37.5A charge current. What I don't really get (unless the BMS has failed or the settings changed) is that if the recommended BMS charge current cut off is 0.5C, how you could charge at 50A anyway.

 

I'm probably missing something. I usually am.

And further, wouldn't one expect the BMS to monitor the charge current and either limit it or turn charging off if the charge rate exceeds a safe current?

 

 

Also, a charge rate of 0.5C seems a bit odd when battery posts must be designed to carry enough current discharge at at least 1C without overheating.

Probably. That's why I was wondering if it was a test with a failed BMS(or altered settings), which is presumably the worst case scenario the plastic fuse thing is catering for.

 

ETA. I can't imagine a new battery would exhibit either of these though.

 

I really must pay more attention to my own thread.😂

Steady on old bean. A bit drastic, don'tcher think?

Its also interesting that at least one of the manuals states the use of ANL fuses between battery and load/inverter. I thought T-classes fuses were preferred. Though I suppose it could be an out dated manual I am looking at.

BMS FETs cannot throttle the charge rate, these FETs are solid state switches either on or off.

 

Given that in BB's own video they advise that charging at 1.0c is possible though at the risk of reduced longterm battery life expectancy, we can assume the configured BMS charge disconnect current was just over 1.0c.

Good thinking Batman, I hope Will's voluntary paralegal army clocks your observation.

So did I but someone on this forum said the benefit of a class T fuse is questionable at 12v. More of a 48v thing I understand, though I write this based on nothing more than internet hearsay.

I think the battery in question was 100Ah.

I don't know. However the manual talks about series connection on batteries up to 48V.

There seems to be some confusion over talking about the 100Ah battery and referring to the 75Ah data sheet(s). I think Will tested both batteries.

 

The 75Ah data sheets specify both 37.5A and 50A max charge current though, with a recommended BMS charge current cut off as 0.5C.

I suppose what is required is some kind of cylindrical re settable fuse for which testing is complete, and patent obtained.

I hear that when judges see that kind of stuff, they usually dislike it and go punitive. 🍿

 

Bizarrely, to my limited understanding of the case, even if they succeeded in reduced max charge current per spec seen by the court, current in either direction will provoke the problem. It's not an SOC problem, it's an I²R one!
