Can I leave a request for Sanyo 18650GA 3500 mAh? I used them several times and they broke quite often. On https://batterytools.net/ I have read several reasons for battery failure. For example wrong coast charge voltage, free inter-cell joins or associations, misfortune of electrolyte and tall and uneven temperatures. Like this, I have not noticed, and so I don’t know what to do. Can you tell me what is wrong with these batteries or maybe they have features in use? Thank you in advance.
I see just 3 entries for such a thing in AliExpress, out of which just this one is selling it in small quantities. The size is nearly a match of two C cells (26500) in series.
Nothing to write home about capacity or energy density wise. The «8C» discharge rate claim is the only somewhat noteworthy stuff. I wonder what is the target market for such a thing.
Energy density in batteries available to the public hasn't increased in the last 6 years or so, by the way.
Rather than taking your chances with Ockered, I’d go with Sofirn’s offering (SofirnLight.com).
Previously they were labelled PLBs (the 5000 mAh) and I believe these would be equivalent to Schockli 5500 mAh (lygte ). I just so ordered some, good pricing (for 2) and free shipping with orders above $29 (USD).
But if your query is for HKJ to test, disregard my post.
Does Vapcell have a rewrap of these EVE 33V battery? (there are too many Vapcell 18650 battery models right now, and it gets a bit confusing, which is a rewrap of which battery internally)
