Saw someone posting about a li-ion battery cell in the chat. Did some quick research and turns out it seems really good.
The cell is:
Sony VTC6
Capacity: 3120mAh
Max cont discharge: 30A
Price: 3.69€- 6€
The cont. discharge is insane on these, the king has imo been HG2 for discharge and 30Q for value. These have higher discharge and really low price right now on Nkon on 100+. https://eu.nkon.nl/sony-us18650vtc6.html
What are your opinion on these and have someone done some real testing on them?
Yeah, and IIRC, the 30q still just barely edges them in 15a tests as well… and are also cheaper and have a substantially higher cycle life rating… IIRC. For a bit higher current applications, the VTC6s might be a slightly better fit than the 30qs… otherwise, I think the 30qs are still the reigning king overall.
Also, if you look at the data sheet, the VTC 6 seems to degrade at an alarming rate. It states 55% capacity after 300 cycles at 10 A. Of course, this is continuous current, but still a lot worse than 30Q’s and HG2’s. I remember reading on some vaping forum who did a comparison test of the VTC and HG2 and the VTC lost its voltage under load relative to capacity advantage after only 20 charges and the voltage plummeted thereafter. Just something to think about since I myself have not done these tests.
