Hi Dennis! I'm gonna publish QB18650 2000mAh 20A high drain cell's test and right now i'm testing a very popular 4S LiFePO4 balancer board. Stay tuned;)

Unless I’m mistaken, or the regional use of English differs from that used in the US. I believe the proper use of the term would be ‘centigrade’ rather than ‘centi-degrees’.

Is it possible to connect these as a 19.2v 6S1P? You can find 3.2v BMS but then I don't know how to get that nicely into a tool battery shell. Would be amazing to create a 2500mah 70A CDR unit.

I believer the A123 battery is lighter than the QB. So specific energy would be better for the A123. Important for use in RC or other weight sensitive items like my small boat.

Anny rivals for the A123 on the 18650 scalle?

How about longevity? Do you tested it for maybe 100,200,300 or more cycles?

It's useless to test a LFP cell for 300 cycles. Their cycle life is MUCH more

I have a data sheet that says you can charge the A123 to 4.2v at the absolute max. I have charged some cells to 4.3v and nothing bad happened. Check out my channel if you want to see what Im up to . Thanks

Please don't spread misleading info trying to get a couple of subscribers. There is only one official datasheet for A123 ANR26650M1B which says: Recommended Standard Charge Method: 1C to 3.6V CCCV, 45 min Recommended Fast Charge Method to 80% SOC: 4C to 3.6V CC, 12 min You can overcharge it to 4.2V but it doesn't mean that it's the way you should do.

@@ThunderheartReviews Such a thing did exist. It might have been an old version of the datasheet. There was talk of this on the DIYSolar Forum, someone mentioned when he started playing with LiFePO4 over 10 years ago the information being given out was very different from what is generally accepted as correct today. A specific point that user mentioned was charging LiFePO4 to 4.2V. The chemistry does not gain anything from going so high but its unlikely a very short time spent at that high voltage will do any serious damage to the cell or its capacity.
