@BoRRoZ any link for ‘reputable’ 18650 batteries?
(I don’t want to build a powerwall, just looking for a few to experiment…)
there are a lot of fake 18650’s out there in the wild
I’ve been lucky sofar with some Chinese suppliers but that’s no guarantee.
a good original (Panasonic NCR - the best!) 18650 can deliver min 3300 mA.
compare - http://lygte-info.dk/review/batteries2012/Common18650comparator.php
I suggest pay a bit more for the real deal and in NL

(It’s not for the difference in price, but I tend to have much more problems with EBay delivery than with AliExpress, so when I have the choice…)

Yes, that’s my experience last couple of months too… better service,better prices and faster delivery at Ali Express and Banggood for the 'flashdeals
The black ones cost 21,05 now. All other colours go for 19,31. Might just be true the black ones are a bit conductive. I’ll order a tray of the blacks. We’ll see in a couple of weeks.
Anyone need audio notifications for their next lorawan project, all in one CHEAP audio player

Just got a couple of these and .mp3 players with on board memory for an automated roller door application - audible warnings. I am thinking it would be hilariously funny if “unpredictable” audio occasionally and randomly just happened on the speaker…
