I have no idea how legit that light and battery are but there are a lot of products that can be made and sold dirt cheap if you donāt care about the quality or brand. Here is a pack of penlights (no batteries though) for about $18:
I use a propane torch on graveled areas instead of herbicides to avoid chemicals.
I only singe the weeds very quickly with the torch and that is enough to kill the exposed foliage from the interior moisture in the weed bursting the plant's cells.
The weeds do grow back since the roots do not heat up enough to be killed but after a few times getting the foliage's attention with the torch about once a week the weeds do seem to eventually die.
It seems to me like the actual force of the jet coming from a propane torch blows a lot of the heat out and away when you have it close to something. Iāve never had good luck with using them for weeds either.
Personally Iām going to keep using chemical weed killers. The studies on them, litigation that followed, and media portrayal of both arenāt really painting the whole picture:
Wondering if anyone who understands batteries can tell me if the 18650 from an Olight S2R Baton II Will work in the Manker MC13?
The Manker website just says:
Kindly note: This item has included 1x Manker high drain 18350 battery with Type-C USB charging port.
Kindly note: If you select āyesā under item option ā with 18650 tubeā, you can also use 18650 battery in your hand. We highly recommend you to buy high quality high discharge 18650 battery
I mean, I assume it will āworkā but will it work properly? Are there any risks involved? Could I harm either the battery or the flashlight?
Okay, so to clarify, your talking about using the 18650 tube on the Manker MC13 so they both use the same size battery?
I donāt have either light so I did some quick research on them. The Olight battery is a specialized unit that has both positive and negative on the positive end and is also a button top. I believe that it should work in theory on the MC13, but there is a very real concern that the spring on the head of the MC13 could bend or tilt and make contact with both the positive and negative on that Olight battery and cause a direct short which could be disastrous. I would not take this risk. I would just get a regular 18650 battery.
The Manker MC13 comes with an 18350, and has an optional 18650 tube I have also ordered with it.
I cant be sure what size 18650 the Manker tube will accept yet. I ordered it a few days ago and its still in the mail.
The website doesnāt specify beyond what I quoted in my posted question above.
You say my olight battery has both positive and negative on the same end.
Is that what ādual polarityā means?
Maybe I could cover the end of the battery in electrical tape so only the button top was exposed?
The other end of the battery is still a metal contact.
I know the Olight batteries in the Warrior X Pro and M2R Warrior Pro are modified in such a way those flashlights cannot even use any other battery. However, Iām pretty sure my S2R Baton II can at least use other 18650ās but just cant charge them. So Iām not sure its AS modified as the ones in those two flashlights.
What actually made me even consider this may not work is the fact that the 18350 the Manker comes with is 10A, and my Olight Battery doesnāt say what amperage it is. (I donāt know anything about batteries and their ratings)
Mankerās website just says to use a quality high drain battery. It doesnāt specify to use a 10A Battery
Unfortunately the whole reason I chose the Manker MC13 with the 18650 tube was because I have two of these S2R Baton II 18650ās and expected to just be able to use themā¦
As far as battery amperages is concerned, I donāt know what cell is being used under the wrapper of the Manker 18350 or the Olight 18650.
There do exist 18350 cells capable of 10 amp continuous output. Cells are put on a special testing device that maintains 10A as the battery voltage drops from 4.2v to 2.8v and the cell temperature does not exceed itās rated temp. This is not the best test to use simply because flashlights donāt usually maintain the same amperage. Most start off with high amperage and then it gets lower and lower. Still, itās a pretty decent test to compare one battery to another battery.
Only high drain 18350 can maintain a safe 10A continuous output. When you move to the bigger 18650 cells, even a high capacity version can safely maintain 10A. Even without knowing the exact cell that Olight is using in their S2R Baton II Iām pretty sure it can safely maintain 10 Amp. So that is nothing to worry about.
Iām not sure why you want to risk a fire or an explosion when you should be able to buy an 18650 cell for between $5 and $10 USD. I see youāre in Canada, are you having difficulty getting batteries?
Thanks a lot for the response and info. I really appreciate it.
I havenāt really looked into buying any 18650ās as Iāve pretty much only been looking at flashlights that come with batteries.
I chose the Manker MC13 over the Acebeam E10 because I assumed Iād be able use one of the two Olight 18650ās I already have.
At least it still comes with the 18350.
Thanks for saving me from the previously unknown risks!
Edit: Looking up batteries it seems Iām in way over my head as wellā¦ Iām far too uneducated to understand all the different ratings and numbers. You can buy an 18650 with all sorts of different Amps and Voltages (I understand NOTHING about electricity, and frankly I donāt have the potential to ever understand it.)
It seems you have to be an electrical engineer or something to understand what Iām looking at to choose a battery.
And they range from $10 to around $40 for any branded ones.
