“This is bad cells”? How about, “These are, bad cells” :bigsmile:
Great review BTW, thank you. Before I knew any better, I bought 4 of these with exactly the same results you posted above. Their crap.
Can’t believe you wasted your time on this but it should probably be pinned as #1 thread in 18650 batteries section for all beginners that are convinced they have 4800mAh cells…
In that case you would have to destroy/disassemble one or some quality cells so you could make comparison and say something like:
“this is crap cell, look what’s inside …. and this is good quality cell, notice how it looks inside…”
all followed by pictures that beginners could compare for obvious differences…
On other hand this graph says it all
49% of the reviews on this Amazon site this gave the batteries a 5 star rating. I wonder how many of them are shills? Or is it “if it lights then the batteries are great” mentality?
Most people are just not aware that they have been blatantly misled and lied to. Pretty much like 99% of everything that we buy from there. They can do anything they want, they are exempt from us law. And boy oh boy, do they ever run with it. :Sp
One of the guys I work with brought in a Trustfire light with a Ultrafire BRC 4800mah battery. I sent him some articles on how dangerous they were and he immediately tossed it. I gave him some Sanyo laptop pulls (measured at about 2000mah) and he was totally amazed at the increased runtime. Another guy had a Ultrafire 14500 in his sk68 that had a runtime of about 5 minutes. I tested it at home and it measured out at 100mah. Gave him an A&W I had lying around and he was also impressed by the increased runtime.
Both are technical guys (a DBA and a network engineer) so luckily they were open to articles and reasoning. Took less than 5 minutes for them to see the light (pun intended :laughing:
I sure hope someone at Tesla sees this. They can cut-down on the number of cells they need by 1/3. I bet it also sags less and has a longer cycle life. I see on one site that 9 sucker buyers have already jumped on it.
