Those PVTSO batteries aren't Panasonic. They're a rewrap of something.
And since there are no batteries with a genuine rating above 30A I would be very suspicious of any of their ratings or claims. Glad you're happy with them though! That's what counts.
Hmm in the ad they were called Panasonic

They do totally outperform all my other batteries by a huge amount, I have 4 vtc5, and 2 vtc4s (at least that's what they're supposed to be!)
If I take my 5's to work I have to switch them out near the end of my 12 hour shift (8-9 hrs into shift), with these VTSO ones I'm barely at 1/4 empty getting home from work, and then vape all night 'till bed where at that point they're still at 1/4 charge! (IPV3 Li with Crown at .25 or dripper sub ohm duals). All my batteries were paired when I bought them and have kept them married, and I only low charge them on Nitecore D4.
