Help re Rechargable 18650 Batteries

[Trek]

Well. There's so much information on there . . . seriously, if I wanted to check the credentials of a battery on some random web-site how would that database help?

I just thought it might be of interest and help someone make an informed decision when some companies advertise ridiculous fictional specifications for their batteries, that is a proven database you could compare, if you think looking up a make or manufacturer in alphabetical order is too much that’s fine.

‘You pays your money, you takes your choice” What you might have found is when buying a certain make; the difference is night and day and burn time is greatly increased.

Some sellers merely re wrap cells and most users obviously are completely unaware what the true capacity is. I also put the database up in case like me, some also carefully re-cycle discarded battery modules and then you can see exactly what the battery and capacity is, as in most scenarios a failed pack/module only has one or two cell failures. It’s surprising how the ratings differ from what was stated and what the actual battery capacity was. I’ve used Li-Ion batteries for years with radio control using specialist chargers that cost between £100 to £200, the batteries are balanced charged if multiples, at a charge rating of .5C to 1C, something a usb charger will never do.

If y'all want the best cells for your lights you can't go wrong with Moli cells, for raw naked power they're the mutts nuts - don't waste your brass on owt else!

Yes that’s all I ever buy, plus if you are lucky you can get the new P50B 21700. 5000mAh-60A

P20 cell if you can find them, or the P30B as a replacement, steer clear of any LGchem cells out of China - their build quality is sub standard IMHO!
