Fried my flashlight? Lumintop ODF30

[New Release] Mankerlight E05 II AL/Cu 1300 Lumen Highest Output Pocket EDC Flashlight in 14500/AA Class and this one Review: Manker U12 (EDC, 20700, Rechargeable, XHP50 II)
Just seen this a few days ago. There are others I’am sure, I know nothing about them though as I don’t own a USB C type yet.
Manker seems to make quality lights though.

Sound like a capacitor went bad, and possible you might have a defective xhp 70.2… i think amazon should take care of it…

By the way, i ordered my odf30 from banggood this afternoon. I hope i dont run into problem like your…

That battery in the pic is not backwards. There is a “-” right next to the High Capacity text. The negative end is in the tail cap. I don’t own a light where the positive battery tip goes in the tail cap. I have a few Lumintop batteries and a bunch of other name branded cells and on all the ones I have, reading the text on the battery from left to right, as is the norm. The left is the positive tab and the right is the negative. Am I missing something?

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. :slight_smile:

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. :slight_smile:
