That seems strange, the crafty might show the same stats as before but should deliver better battery capacity after the replacement. Maybe you got the old and new battery mixed up or damaged a cable?Has anyone had success with replacing the battery in one of the craftys that came with 20% extra battery. I've tried doing mine but the crafty seems to think it's still the old battery and is still only giving me about 1 session.

haven’t experienced any of the issues that Jcat mentions, but electrical discharge can cause strange behaviour, letting it sit for an hour before installing the new battery should help you avoid those kind of issues. If anyone needs a battery pack in EU hit me up as I didn’t find it hard to build at all. Cost is around the same in € as JCats price, although im unsure of the shipping costs.
Just changed one in a crafty +, opted for a 3500 mAh witch proved to be a waste since the maximum charging capacity is set to 2700 something. Recommend all to opt for the original mAH witch if i remember correctly is 3300 for the crafty + and 2900 for the crafty until a way to change max charging capacity is found.That seems strange, the crafty might show the same stats as before but should deliver better battery capacity after the
Have you tested your batteries in Crafty+ models? I may need one in the future as it seems to be the most common part to fail
Don't worry too much about this, it probably has no impact at all on real world runtime of the battery. The circuitry is only capable of measuring voltage and uses that to estimate capacity. With a higher capacity cell it may give you incorrect information about how much capacity is remaining (it will estimate a percentage that is lower than actual) in cells but it will keep going until they reach the minimum cut off voltage.Just changed one in a crafty +, opted for a 3500 mAh witch proved to be a waste since the maximum charging capacity is set to 2700 something.
Okay, are you sure these values are measured and not set by s&b? Sure some of them are, but I’m not so sure of the design charge capacity. Since the batt I installed was a 3500 mAh and not a 3300 mThese are some of the values I get trough vapemeister:Don't worry too much about this, it probably has no impact at all on real world runtime of the battery.

I have to agree with @badbee that it is unlikely that the mAh values matter that much ... I'm not sure how it would actually read this either as I have no idea how it would (beyond estimation as @badbee mentioned)
I would tend to agree that charge/discharge should only be limited by cut-off voltages, so although these values may impact the accuracy of the battery % remaining estimate, it shouldn't actually have any effect in use.
You may be able to write those values or you may not; some BT characteristics on the device are writable and some are not (ie. if they weren't you wouldn't be able to change the temperature for example!)
Battery is outside of the vapour pathWas getting tired yesterday posting Just did the math which I hadn’t yesterday.. 80% of 3500 is 2800 mah so it’s just 6 mAh difference from what would be optimal for the battery, so that truly is negible but still could be worth looking into this for when batteries reach a higher capacity. Will still test to see which values are writeable and which are not.
btw just discovered that my solder contains KOLOFONIUM, which probably shouldnt be used in the vape. Buy a more expensive solder that contains silver and is pure from toxics.
Completely agree with you, but the battery gets hot and I’m not sure at which temperature the KOLOFONIUM releases particles. Even though I’ve used electrical tape it could still be brought in to the intake since the intake is above the circuit?Battery is outside of the vapour path
I had to look that up, it's the Swedish word for rosin. Don't be too worried about that either, rosin is just a mild acid made from pine trees that removes the oxidation layer from metals so that solder will bind properly. All electronics are treated with rosin or flux (they are essentially the same thing) when soldered. It's harmless. You are problem more at risk from the car exhaust from the street outside your house.KOLOFONIUM
Didn’t read into it tbh, just saw the warning on the box and that it said it shouldn’t be inhaled or be touched too much as it could cause irritation. As a proper swede I felt that I needed to warn others tooI had to look that up, it's the Swedish word for rosin.

Can I buy these here in the UK? How much is shipping?I'm selling these packs for $40 USD + shipping.
unfortunately, jcat is no longer selling these as per his post one page back:Can I buy these here in the UK? How much is shipping?
Hi everyone,
unfortunately due to rising costs of cells and shipping, and concerns around shipping of dangerous goods, I’ve decided to stop (at least for now) this service.
I have a few cells left that I may send out within Canada/US, and will look into dangerous good shipping options in the Fall, and will resume this service if I can do it for a reasonable enough price.
unfortunately, just with the increased costs in cells, I will have to at least increase the price to $50USD vs $45, and at that cost, and with a likely shipping increase, I just don’t see this as viable.
sincere apologies, and thank you everyone for the business over the last few years.
all my customers have been a pleasure to deal with
You are fine with that cell. Charging is based off standard Li Ion voltage levels, the charger cycle isn't controlled at all by capacity. There is the possibility that it will be slightly off when it indicates how much remaining capacity your cells have when in use, that's no big deal, probably not even noticeable.A couple years ago, I bought a pair of NCR18650PF and tried to replace the battery in my crafty "classic." I messed up, soldered the battery in backwards, and fried the board. I'm now using a crafty+ (micro-b, not USB-C) that after 2 years and 380 hours is finally giving up the ghost. Usually I'll get the red and blue error light when trying to charge or use it, but it can be persuaded to charge sometimes.
My question is this: would putting the lower capacity ~2900mah PF cell in the crafty+ (that as far as I can tell uses a ~3500mah GA cell) work? My primary concern is that the crafty+ might try to overcharge the lower capacity cell and cause heating/fire hazard issues, but I'm not well versed in electrical engineering (obviously). A soldering iron is DEFINITELY going to be cheaper than a new vape if that's a viable option, but if not I could probably find a better use for that PF cell.
Tagging @JCat because they seem to be the resident authority, but any and all information is appreciated. Thanks!
@badbee Thank you so much! Per your advice, I swapped out the batteries yesterday and, after a few hours of charging, successfully vaped a solid bowl. It was just enough leftover/shake for a single bowl, but the vapor was significantly denser and more flavorful than it's been for quite some time.You are fine with that cell.

It's generally recommended that the attachment blades be spot welded rather than soldered to the cells. Soldering irons tend not to be hot enough which means leaving them in place a long time which can cause heat damage to the cells. Spot welder is hotter but can be used much faster so less total heat into the cells.
It's always good to hear a success story rather than the usual tragedy@badbee Thank you so much!

The PFs that I ordered many moons ago had tabs already, so it was a relatively straightforward matter to de-solder the existing battery and re-solder to the new tabs. Again, thank you so much! Not only has a significant amount of money been saved, but I've also learned a new skill and slightly reduced electronic waste in the process.
Yes, a Murata VTC6 is an excellent cell and will work fine. In the US we tend to avoid buying cells from Amazon because sometimes they are fake. I've heard https://eu.nkon.nl/ recommended for buying cells in the EU but double check the prices aren't too high.Sorry to kind of post this again, but I was pointed here from the the other thread.
Just want to double (no, triple!) check that these batteries are okay for the Crafty (not the + ... although the box has a sticker saying "20% more battery" (or something to that effect) There is no + symbol on the actual device.

From what I understand they're a better all-round battery. I just want someone to say "yes" they'll work. I have found someone who'll do the switch for me but they asked me to provide the battery.
I live in Italy so it would be good for any other fellow Europeans to know as well, maybe?
Thanks
