If it does not have polarity protection, it will not be the first Lumintop model that does not have it.
A friend of mine fried an SD10 for that reason.
There are
The first one that came to mind: Olight S1 mini
I contacted Lumintop last night, they confirmed it does not have polarity protection.
They also confirmed the positive side goes towards the LED, negative towards the tail.
Kinda bummed about frying the flashlight, but thankfully Amazon has great customer support!
It doesn’t have reverse polarity protection, so make sure you put the negative in towards the tail and you will be fine.
RPP should be mandatory in these flashlights :person_facepalming:
I almost damaged a Manker E11 due to that as well! Sorry to hear this and I hope :
a) that Amazon helps you on this
b) manufacturers start to make lights with RPP AND warn users/buyers if the lights sell don’t have it!
The User Manuals got to serve for something… :person_facepalming:
Yes, Amazon has already paid for the shipping back to them and will give me a full refund.
Not sure why RPP isn’t included in the lights, it would save the companies money because their lights wouldn’t get fried and returned to them! That, or put in the manual a warning like you said.
What you say is true. However, I would not recommend a light that takes lithium-ion cells to anyone who is not familiar with their safety issues. You mentioned you weren’t paying attention when you put the battery in the light, and might have put it in backwards. That is dangerous! On some lights (with multiple cells) it might cause a short and do a lot worse than just smoke a bit.
Not paying attention to the proper orientation of cells is fine for alkalines or NiMH rechargeables. I’ve done it myself. But you have to be a little paranoid when using lithium-ion cells. They’re safe, but only if you follow all safety rules.
The manual should definitely have warnings about that.
Oh, one other thing: I wouldn’t personally buy lithium-ion cells from Amazon. Depending on how they are put in the warehouse bins, you might be getting fakes even if the seller is good.
What makes you think it’s backwards?
Where do you suggest buying Li-ion batteries?
I do a lot of business with them.
Yea. I will be careful… this light is similar to the jetbeam t6. You have to insert the battery correct position.
Unless otherwise stated the positive goes towards the head of the flashlight. Just like the old maglights and every other flashlight from a kid onward.
But in this day and age especially lumintop should have reverse battery protection. Either physical like nitecore or electrical.
Is this your first flashlight?
I would be highly surprised if the manual doesn’t say don’t insert battery backwards
If the batteries are icr then yes a direct short will most likely cause a vent with flame or this case a pipe bomb literally. But if it’s a imr inr chemistry. It may just vent some when it gets overheated. If you look at battery spec sheets. They have to be direct shorted for hours with no flame or explosion. They have to be overcharged at 12volts and 3x the mah for hours. They have be cooked in a oven. And crushed vertically horizontally. And violently shaken.
But no I wouldn’t recommend lithiums to someobe who doesn’t have a little common sense.
I have had shorts in lights I built and thought I had enough reflector clearance and smoked the drivers literally. Comes up under the lens. And melted springs before also.
Only thing I can guess is maybe staying up to late. :confounded:
Funny part is when I saw the pic I thought the battery is in backwards when I saw the negative on the tail cap end.
I will never live this one down. :person_facepalming:
Nope never
Oh come on, yes, we got to give him a pass based on sleep deprivation. 
I apologize to the OP, poor Zane probably spent half the night trying to figure what the *ell I was talking about. :person_facepalming:
Hello Zane,
Regret to hear that and the unhappy purchasing experience happens to you.
Due to the high current output, ODF30 is designed without reverse polarity protection indeed.
So, when inserting the battery, please make sure and make sure that the positive side goes towards the LED, and the negative towards the tail.
Next, we will make a notice about this issue.
Thanks for the supporting.
I'm new here and this is my first post. :-)
I recently purchased a Lumintop ODF30 Flashlight and same battery from Amazon as well. And, made the mistake of installing the battery backwards. After removing the battery, I smelled the smoke too. Light didn't function after re-installing battery with the proper polarity.
Looking at the manual and flashlight, there doesn't appear to be any reference to the correct polarity for the battery. It's been my experience that most flashlight use a spring on the negative poll with few exceptions. I will never make that assumption again. :-P
I ended up watching a youtube video about this light to gain insight into how the battery should be installed: https://www.youtube.com/watch?v=RAII-erOb6I&t=261s
I'm under the opinion that this battery does not have reverse polarity protection. Perhaps, if I had I used a protected battery, the flashlight wouldn't have gotten fried.
Regret to hear that again 
We have learned the lesson that to make the visible notice if there is without reverse polarity protection.
And here we again, to make the notice:
- To use the battery WITH a PROTECTION CIRCUIT, to prevent reverse battery installation.
- MAKE SURE the anode side towards the LED side when inserting the battery.
Otherwise, the light, ODF30, would be damaged when reverse installing the battery without a protection circuit.
Make the notice like this instead:
1. Use a protected 26650 battery to prevent a reverse polarity battery insertion.
2. Put the positive side of the 26650 towards the LED side of the light when inserting the cell.
There is no reverse polarity protection present on the light. Therefore, reverse polarity results in a damaged ODF30.
