<br>
That's consistent with reports of Chinese factories pulling apart<br>
stuffed laptop batteries, relabelling the extracted cells for on-selling<br>
as brand new total junk. Then they end up on trademe, with clueless<br>
sellers saying they never had any complaints and "anyway, many sales =<br>
good quality product". 'nuff said.<br>
<br>
There's are lots of what's collectively referred to as JunkFire(TM), but<br>
no proof that they're ever of any quality.<br>
Capacity claims are lies more often than not.<br>

I found 1 seller on trademe<br>

who sounded like he knew what he was talking about, but he isn't selling<br>
any more. I have his Samsung and Panasonic models and he made sure they<br>
were not fakes.<br>
<br>
Aliexpress doesn't sound like a good choice.<br>
<br>
Given the situation, where would I best buy something like a dozen 18650<br>
for a reasonable price, >= 2Ah, and no protection?<br>
<br>
Can people post their good and bad brands, models and sources/sellers<br>
(all of these please, or it's often of little value)? It's likely of<br>
interest to others too.<br>
<br>
The application is powering some stuff for a 5-10 days, I intend to hook<br>
cells up in parallel, with those little protection boards as discharge<br>
protection. Charging in standard chargers, if I have to re-charge once<br>
that's OK.<br>
<br>
Thanks muchly,<br>
