HaikeLite XHP70 Thrower Prototype Sneak Preview

I’m learning a lot here. Thanks TA and Stereodude. Just a detail to add here: I do believe charging in series does happen with flashlights. For example Lumintop SD75 (2S2P), and Nitecore MH41 (2S). I have been wondering for a long time whether unbalanced charging of lithium ion occurs with products such as portable vacuum cleaners etc…

Yes, in some lights they charge in series but lets just say that people that use internal charging doesn’t really care about the cells anyways. I have yet to see an internal charging system I truly trust or feel like waiting on.

I feel the same; however, this is actually the weird part. No doubt you’ve seen plenty of videos where people put different cells in their Skyray King or something; it happens all the time.
So you have unbalanced charging in certain lights, and it is exactly the not so careful people that put different cells in these lights for use and charging without ever taking the batteries out again. And apparently things don’t go sour… Certainly not recommendable, but this is perhaps your view how the dangers of lithium ion are exaggerated? Meaning if you have a set of quality cells from the same batch, it is pretty much impossible that things go wrong in 4S configuration.

Yes, that was exactly my point. Even when abused the cells themselves are actually quite safe now days.

I have even tried shorting them out on purposes (as was documented in the Q8 thread) and there was another thread where a member tried to get them to explode and it was surprisingly hard to do that.

The dangers of brand name 18650 cells is really not all that bad. Don’t short them out, keep them at reasonable temps and keep the voltage between ~2.75 and 4.2V and they will work fine.

HaikeLite, could you please explain very briefly the positives of the different battery configurations you use in this lite?
I mean 4s vs 2S2P. Probably I missed this lesson…

+1 And please at least provide realistic runtimes of the 4S version, how different is the regulation?

My 4S MT07 and MT03 samples are supposed to be shipped out this week via DHL. Based on past experiences with DHL they should arrive before the 27th. I should have enough time to get beamshots of the MT07 vs MT03, as well as Turbo and high run times before the end of the GB.

My set of flattop GA cells is going to be here in time so it just comes down to the shipping.

Ahh, good! I just asked them via a pm if I can convert mine to 4S...

Maukka mentioned he was getting the 4S tailcap and driver.

Outdoor beamshots are now posted see bottom of the OP in the review here: https://budgetlightforum.com/t/-/42543, hoping they came out better, but I'll probably be giving it another go the end of this week if the weather cooperates.

I did, however, apply a resistor mod last night (added an R075). Mode outputs on frssh charged set of SANYO GA's are now:

  1. low-low: 56 lumens
  2. low: 610 lumens
  3. mid: 1,570 lumens
  4. hi: 2,530 lumens
  5. turbo: 5,300 lumens @30 secs

Forgot to measure moon, but it's still very low...

Thank you Tom!

Really nice mode spacing on the two Haikelites btw…

Man, thats crazy :slight_smile:

LOL! I showed that pic to my girl, and she nearly passed the fuck out! Figured I’d show her that there are guys who have the addiction WAY worse than I do, so she should stop her complaining! :stuck_out_tongue:

Glad I could help

pakarherbal, why do you keep on posting this same message?

Isn’t this against the forum rules?

SB has had to delete an user account like this the other day. Their new spam tactics are to pick a thread and spam within it, versus starting a new thread that gets deleted immediately.

What I don’t understand is why that spammer keeps on spamming in this same thread… (I have seen that post here several times now) :question:

where can i buy this SMO reflector?

Me too - very interested in getting an SMO reflector for this light.
