Sofirn SP36, impressions of a sample

Thanks so much for the answer. Anyways last questions…

  1. Do I need to make sure I have the same exact charge between those 3 batteries before putting it and using/charging it? As far as I understand, it should be fine right? It’ll automatically balance itself ye?
  2. Do you have a PDF for the how to use it? Like it’s so much different than my old flashlight so I’m kinda confused haha. Thanks eh

Whoa da. As far as I know, you should/better use the same cells, preferably bought the same time, charged to the same level. You do not want one cell at 3.6V and another at 4.2V because the two will try to level each other quickly, and that's not healthy...

Close is ok, like 0.02V or so.

The light didn't come with a manual? If not, it's the same as the Q8 - there lots of info around on usage, maybe the best is the videos.

Yes I bought it at the same time so it’s as close as possible. Also my flashlight is still shipping. So idk I think it should have a manual. But yeah I thought since it’s kinda complicated, I’ll learn how to use it from now haha. Thanks for the link!! :slight_smile:

You can download the NarsilM 1.2 manual from my ► sharepoint ◄ (in English or German language). I'm in touch with Sofirn if they agree to let me publish the entire manual (i.e. with the first page about the SP36) as it is now available on Amazon as well.

All three batteries work in parallel. Make sure that these are charged to the same level before you put them into the light. Otherwise the springs are at risk to melt due to immediate leveling of voltage between the cells, just as Tom E already explained.

Thank you so much. It’ll definitely help me getting used to the control :smiley:

Hey guys. It’s me again. I have other questions. So . I’ve done more research and it seems like Anduril is a newer different firmware? Or more updated firmware? And im new to all this so I want to know if it’s better with more features or no?. Also how do I flash it if I want to flash it to my still shipping SP36? Thank you. :slight_smile:

You are a parallel thinker, are you? Everything sorted out before the flashlight even has arrived!

The advantage of that is that everything is ready steady go beforehand, the disadvantage is that some of your questions never needed asking and answered once you have the actual light in your hands, or that you at that point may even choose a completely direction than what you figured out before.

(I’m a serial person myself)

Hehe. Sorry if it seems like I ask a LOT of questions. But I like changing firmware etc. And why not if it’s much better than the stock firmware? :stuck_out_tongue: . Thats why I rooted my phone and changed the ROM etc :stuck_out_tongue: . Anyways. Back to the questions. Can you or anyone explain/answer these questions for me? Hehe. It made me so excited when I know I can change the firmware hahaha

If you want to try out different firmwares, you should use a more “modder friendly” flashlight.

Ahh… So it’s very hard to mod the SP36 ye? Thanks for your reply :smiley:

If you scroll through this thread you will find that many people think that the glued driver is too much of a problem to handle. Every mod with the SP36 starts with getting the driver out. I managed to do that and so did Anthon, so it is doable.

I see. Too hard for first time yeah? :stuck_out_tongue: .

Not neccessarily, you need to have a certain preparedness to screw things up and then you will be fine :stuck_out_tongue:

:stuck_out_tongue: Is it that much better tho? The firmware? Anyways another question. I know that on default turbo is timed to about 3 minutes (?) Before stepping down… say I changed it to 7minutes. And it goes to a critical temperature which its so hot it could damage it… does the firmware has this limit on temp where it will step down even if I set the turbo limit to timed and not temperature based?? Like basically a thermal limit that can’t be disabled…

7 minutes gets the SP36 burning hot but it may not kill itself yet. Just try it out and tell us. As I said, once you have the light in your hands, get the manual and try everything from own experience, you may even stick to Narsil because it is a great UI. And no, there is no ultimate fail-safe feature on this light, if you want timer stepdown at 7 minutes, it will step down at 7 minutes period, if you want a thermally induced stepdown you will have to set it that way. Btw 3 minutes I found is a sensible stepdown moment if the batteriescare full.

Or I guess I could just set it to 5minutes… anyways can’t wait for it to be here. Been waiting for Sofirn to ship it. It hasn’t been shipped yet. Hmm. The UI will need time getting used to. But that’s fine , it’s worth it. The features are so awesome!! . Also I think the manual/cheat sheet included should be small enough for me to slip it inside the battery holder haha :stuck_out_tongue: . Oh also. Do you and others enable the standby led or not? I mean led like that should last like forever haha. But I’m just worried about the battery drain. It should be cool and good looking tho haha.

Just make sure the batteries are married and have the positive end up, and everything should be fine.

… and by “married” I mean all cells of the same type purchased at the same time, at the same voltage, with the same number of charge/discharge cycles in their history. Basically, treat them as if they are one indivisible battery instead of three separate cells.

As for firmware, be sure to use and explore the stock firmware thoroughly first before deciding whether to switch. It’s one of the best available, and changing it may not be worth the effort.

Yeah I bought 3 same exact batteries from the same seller. It should be close enough. But I guess I should charge all of em first then go put it in. I hope my protected batteries with 6.7A limit each works fine hahaha.

I’d just check the voltage with a DMM first. If they’re really close, they should be fine to go into the light together, and then the light can charge them as one. It shouldn’t be necessary to open up the light again unless you decide to take the driver out.

Yeah I’ll do that. Thanks for the tip ! :slight_smile:
