Hi all. So I've had this Crafty for about 9 months and I love it, except the battery life. The battery has been getting worse and worse, recently it started dropping down from full (solid blue light) to nil (rapid flashing) after only one 10 minute use. Charging would go straight from rapid flashing to solid light in a very short time.
Then, yesterday, it stopped charging at all, I get a flash when I plug in the charger, then all lights off.
I'm hoping the PCB ICs are OK, and the problem is limited to a bad battery. Ever since I owned this unit, it has had a strange symptom of going into boost heat even though I didn't double click. My first crafty never had this issue (lost it on the golf course).
So now I need to do something about it. My plan is two fold:
A) Buy a handheld corded vape
B) Repair the Crafty
A) Need suggestions here.. I want a vape with qualities similar to the crafty, but corded. I don't want a desktop unit. Thinking about the Plenty, but not sure about the vapour quality.
B). OK so some may say, send to S&B. Here's the thing I don't want to Int'l ship something that may have traces of material that has questionable legal status in different jurisdictions.
I am a working electronic technologist with 15 years experience. I am reasonably confident I can replace the battery. I know the risks of working with lithium batteries and am capable of working safely (I am also an electric helicopter hobbiest). I know it will void the warranty.
I'm now in the market for un-protected 18650 cells with spot welded solder tabs.
The original ncr18650pf supports 10A continuous drain current and is rated for 2900mAh.
There are loads of higher drain cells out there but the mAh is lower. I'd like a cell that can meet the drain requirement of the crafty, and last as long as possible. Hopefully there is a product out there that is better than the original.
The ncr18650b has a much higher 3400mAh rating, but continous drain current is only 6.7A, I'm not sure that's enough for the crafty. It may take too long to heat up, or it could be perfect. If it's enough current, the extra capacity would make for much longer sessions. Considering buying a ncr18650b and a ncr18650pf and trying both. Suggestions are welcome.
Thanks for this great forum.
