Why do 18650 batteries stop holding a charge

[Tbev]

The vtc 's are the best for any mechanical mod, go with AW from Provape or the flashlight guys https://www.illuminationsupply.com
I get my batteries there, best IMHO. Fast shipping always real.

If you are using the 10 amp batts and vaping P's max output, amp or watt wise, they will stop powering the P once down below 3.9 volts. Are you vaping at higher levels now then when you started? You actually can use a flat top 30 amp batts in the P, but need those flat top adapters like the ones MadVapes sells. That is what I use in the futura, other wise have to use lower amp batts with unsatisfactory results. Love all my 30 & 35 amp 18650's will power the futura at 30 watts till bat gets down to 3.5 volts.
