went out to the MadVapes site and clicked on the
tests and this is what I read:
"We've tested a few of our PVTSO batteries against some of the best batteries out there to show you a performance comparison. As you'll see from the graphs, the quality and performance of these batteries give Sony and Panasonic a run for their money!
For high-amperage testing, we tested each cell at 8A. This is a good amperage that any 18650 IMR should be able to handle, while also giving consistent results that apply to sub-ohm vaping. A battery at 3.7 volts pulling 8A of current means the resistance has to be 0.46Ω. Builds below this resistance will experience decreased battery life and voltage, while resistances above will have increased battery life and voltage. 8A is the perfect amperage for this test."
Granted, this comment relates to 18650 batteries, but if their idea of high-amperage testing is 8A's I would not trust a claim of 48A.
I WOULD NOT TRUST THESE BATTERIES AT ALL FOR LOW SUB OHM VAPING!
