[Canceled] Sofirn SP70 BLF Edition

I'm a bit confused about those 4.800mAh. Barry are you sure these come from Tesla? Can you please check if these cells are the original Sanyo NCR21700A 5.000mAh? These are also sold by Vapcell as Vapcell INR21700 5000mAh, see HKJ's test here: https://budgetlightforum.com/t/-/54274

I agree with Agro that this battery is not considered as a classic high drain battery but a very good compromise between capacity and intermediate power drain (< 15A). Please have a look onto this comparison between this "Tesla battery" and the PLB-55A cell (to be found in Shockli IMR26650 5.500mAh or Keeppower 6.000mAh). As you can see there is no benefit in using the 21700 Tesla battery but only disadvantages due to less capacity and the need for an additional conductor between both batteries which again increases contact resistance and subsequently leads to additional voltage drop.

If you want to run the SP70 with maximum output, Samsung's 30T and 40T as well as Molicel's P42A are the best high drain batteries.

However, if Sofirn chose to offer the "Tesla battery" separately or in combination with C8G, it would be an intruiging option. :-)

Sofirn, read this. Don’t waste your time with Tesla battery. Too many problems and other good batteries are easy to source. If you were experienced battery company then maybe.

the batteries from Tesla were made by Panasonic 5000mAh

I didn’t know they are not good enough as HD batteries

Barry, please can you try to get in touch with Power Long Battery Technology Co. Ltd in Dongguan, China?

https://www.powerlongbattery.com/about-us

They offer the best 26650 batteries available so far. If Sofirn were able to source PLB-55A cells it would be really great. These cells provide more power than Sofirn's new 26650 HD cells.

If you want to go for 21700 batteries (personally, I'd really appreciate this approach), please try to get cells like Molicel P42A or Samsung 40T for these should have the best compromise between high drain (> 15A) and capacity. Samsung's 30T would not make much sense for it has not much capacity and its benefit over the 40T would only last some seconds with a fresh, fully charged cell.

Something interesting that caught my attention this morning...

So, there actually is a custom version of Andúril that supports both e-switch and the tailclicky forward switch. If we want to have Andúril on Sofirn's SP70 BLF edition, this custom version might be the right thing as flashing the standard Andúril would normally sacrifice the momentary turbo and mode memory function of the tailclicky. Maybe Toykeeper can share with us her thoughts about it. ;-)

Yes, more Anduril please!

Just good a quick and helpful answer from Toykeeper that I would like to include here:

will contact them. Is there any test of their batteries?

That's great news. I'm sure many customers will be interested in buying these cells (maybe even more if offered on Amazon US/AU/DE, too).

As a reference, please have a look onto Henrik's review of the Shockli IMR26650 5500mAh which uses the PLB-55A cell from Power Long Battery.

For my super high amp 6V lights, I've converted over to only FET. The smooth ramping is a little jumpy at the low levels, but at least works. I can fry a 7135 in seconds on those lights. Sorry, haven't kept up with the new designs, but very interested in these alternate solutions. Of course what I want is smooth ramping capability on these other designs, and smooth transition to the full FET. Of course high PWM is a must, and no PWM preferred.

Subbing

So is the BLF Edition SP70 dead?

It’s coming right after we make Q8 extension tubes aka never

Let‘s just hope it won’t take as long as Duke Nukem Forever :-D

Is anyone making a driver for this thing? Like TA? If I have to make my own BLF version I guess I will. I just can’t live with the stock UI.

As someone who was looking forward to this project I really hope that it doesn’t fall under the radar!

NW emitter and Anduril UI (this will also solve the overly illuminated side switch issue)

are enough upgrades for me to jump in.

TA does usually make single drivers. You can use a driver from Lexel or MTN E. It’s a standard 6v FET, no big deal.

My SP70 has become my nightly user, it’s an instant hit with everyone I show it to. I’ll probably pick up another if this blf doesn’t pan out, which would be a bummer. A blf version would be an automatic recommend to all the night guys. And all the camping guys. And all the guy guys. With just a few tweaks and a little price adjustment, I’d be in for at least 3 more lights.

I wish people would not phrase their questions like this. It’s very negative. Just ask how the project is going.

If you want it to be dead you can unsubscribe and forget about it.

If you want to know the truth, you have to be patient.

Sometimes projects get cancelled because they know the costs don’t make sense. Sometimes projects get put on the back burner until the company gets caught up with backordered stuff.

I’m assuming this project is still going forward, but Sofirn is working on a lot of things at once, so development is slow. They might be waiting on a new driver design to support Anduril or maybe waiting on ToyKeeper to tweak the software, etc… You just never know until they speak up and give an update. Even updates are few and far between. I just assume the project is going forward unless I hear otherwise.
