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 don’t 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. I’ve never had good luck with using them for weeds either.
Personally I’m going to keep using chemical weed killers. The studies on them, litigation that followed, and media portrayal of both aren’t 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 ’yes’ under item option ’ with 18650 tube’, 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 “work” 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 don’t 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.
