Has anyone seen or tried this yet???

[MilkyG]

It's a 4V Li-Ion batt made by Craftsman for hand tools. Not too much info there (dimensions, mah, etc.), but it looks pretty interesting. Has anyone seen or tried this yet? I'm pretty interested...a full charge might be closer to 4.5V or so and 4.3 is my sweet spot for DC cartos and dripping on 2.0 - 2.5 ohm attys. Let me know what you think...here's the link:

I'm a bit skeptical about this. Both pics fail to show the technical details on the battery, the spec tab is empty, and the starred rating has nothing to read either. I really wonder if they have taken a standard 3.7v, repackaged it and since it comes off the charger at 4.2v, called it a 4v batt. Ryobi has pretty much the same thing with their tek4, and similar tactics.

It doesnt say anything about a mah rating or size . WHat is 4v ? 4v at full charge . Thats not good since the regular trustfires and AWs all come off the charger at 4.2v

It could be the size of a D battery for all we know . Is there really any noticeable difference from 4.2v - 4.3v . Also if you have a regulated mod you can keep it at 4.3v even when the regular cell is almost dead .

If you zoom in on the angled image, it shows 5Wh.

There's a promo vid for these tools, and it looks rather 18650-ish in size. The drop in charger is neat, but a guy runs a set of headphones with one, so you should wonder how big of a cell do you want in your headphones...

Or just drop these bad boys in a unregulated 18650 mod and go to town! Just make sure to get the charger too.

They have the same battery on electricstix as well. Also, on that site, they have put up some improved chargers that I believe now display green when charged.

The OP said:

Are you familiar with or know what these 600mAh little girls will do @ 1.6Ω?

Where'd you find the vid asdaq? They have the battery on the Craftsman site; but no charger listed

@WillyB I have been using resistances around 2.5 so seeing about 10W. I have not tried a DC using these but if OP likes DC at 4.2 then 2.5 ohm stuff would put him in a similar range using these batts. Questions is valid but I am betting with a DC at around 1.6ohm that at ~15.5 Watts it would be a pretty toasty vape. I do have some DC's and may try it. I am not certain though about the 3+ amp draw on these batts.

I would almost bet, the charger only comes with a tool, and only the batteries are sold as extras.

@WillyB - While I am not a big fan of the DC's I do have about 10 in the arsenal. They ohm out at 1.7. Freshly charged 4.8 NiMH batt came off the charger (no load) at 5.41V. I loaded up a fresh DC with my goto DIY Juice (DIY Cinnamon Roll) and fired up the V2 Rough Stack. I just chain vaped about 2 mls through the DC in about 10 minutes! Hopefully I can get this typed before potty break . As expected vape is warm and flavors for this particular juice have become muted and somewhat washed out. The DC is of course popping and crackling a little louder than normal and putting out big vapor. Outer carto tube is definately what you would call warm. Batt is now at 5.19V (no load) and there is no noticable heat buildup on the batt. While I can not say how long the DC will last I can say that these batts can and do drive them. Granted results are only for 2mls and 10 minutes of use. I am also not sure how many people would really like to vape at this range but certainly there are a few watt pigs out there that would enjoy it. On 2.5 to 2.7 stuff these batts really are a nice addition to the toolbox. Hope that helps and happy vapes.

Liv, just to be clear, you do mean NiMH, yes? With so many chemistry's and voltages in this thread it could get confusing.

YES......Sorry about that. NiMH. I have edited the post. Thanks for catching the error

Well I'm not gonna post my pics again showing loaded volts with 4 AA 2500mAh NiMHs. But regardless of the ohms of the atty/carto about ~7W is the most they can provide. The lower the ohms the more the 4 pack's voltage would sag. I really can't see how this stack of 4 mini 600mAh NiNHs could do any better.

Here's some tests from a UK from. These are the Sanyo Enelope style NiMHs (that is a 4 pack BTW).

Unloaded, 2.7Ω carto and finally 1.8Ω carto. Using Ohm's Law both are at about ~7W.

WillyB - Since pictures are better here is what the cell looks like unloaded and loaded with a DC that is now at 1.5 ohm. Verified on a Vari, Darwin and this little RS DMM.



So using Ohms law that would mean under load ~12.4 watts pulling about 2.9 amps. Anyway the batts are pretty nice and I like them as I stated on the stuff around 2.5 ohms. So if people want to try the Craftsmen battery great all I was saying is this is a nice addition to the vaping gear box and works well for the money.

Sweet, some real pics/tests.

Frankly I'm quite surprised, actually amazed.

Hard to believe that little things do better than full size AA or AAAs.

I do use a dual 18650 VV box mod at 4.3V almost exclusively (I hardly even adjust V any more)...mainly so I don't have to charge as often. But at about 4.5 x 1.75 x 1" it's a little big and heavy (although not a bad size for dual 18650s). But a single batt that maintains a little higher is why this caught my eye. Yeah, a single fully-charged Li-Ion at 4.2V is great...but it drops quickly. So not having to use a larger VV device and instead using a single, smaller batt would be nice. At least until I break down and buy a Buzz Pro or a Provari. Trying to stay on the cheaper end of things.

Off topic, but here are posts of my VV device...

FWIW if "mainly so I don't have to charge as often" is important, after your home built, both the Buzz Pro or a Provari will surely disappoint. You are currently working with a lot of mAh and a very efficient regulator assembly. Plus from figures provided by Para your regulator can handle more amps than the ProVari.
