SAMSUNG 50E 21700 9.8A FLAT TOP 5000MAH??

[sofarsogood]

I keep 30 watts set as a hard limit in Arctic Fox firmware and don't need to go above 20 watts for MTL. So Volts x Amps = Watts. 3.1 cutoff voltage x 9.8 amps = 30 watts. Is using this battery imprudent never the less? I would love to have 5000 mah.

To determine the correct battery with a regulated mod, take your wattage, divide by the amount of cells – this will equal Watts Per Battery (Wbatt)

Take Wbatt, divide by your cut off voltage and then divide by the efficiency of the device. If you do not know the efficiency a good figure is 90%. This will equal your Amps Per Battery (Abatt)

So…if using a single cell device with 30 watts being your limit, and the cut off is 3.1 volts and assuming 90% efficiency the equation will be…

Wbatt = 30/1 = 30

Abatt = 30/3.1/0.9 = 10.75 amps

I think the cut off on the Pico is 3.2V, so there should be only be a 6.9A draw at 20W.

CDR x 3 = max Wattage per cell.
No need to overcomplicate things.

That said, 5000mah looks good on paper, but due to the high internal resistance of the cell and because at 30W you're running the cell at or even slightly above its limit, overall runtime might not be that good or even better compated to the 4000mah Samsung 40T.
Another negative sideeffect is drastically reduced cyclelife, if you push a cell to its limit.
To wrap things up, the 50E might still be worth a look, but don't expect it to be the holy grail of lower wattage vaping.
