[LiFePo4 3S a123 26650 packs and higher than 1A charging?]

I do not know much about charging & electricity so hopefully someone will enlighten me:

Why does the DNA spec sheet state that the device can charge up to 23 amps while typical is 9 yet Brandon states that 1 is the default and the max?

[Device will not turn on without power cable]

I too am experiencing this problem although it did not occur as a result of a possible short. The first time my Hcigar VT200 shut off with no warning and did not come back on for several minutes after plugging into power. Now, the device shuts of at least once a day and will come back immediately after plugging in. It also does not always recognize when a coil change has occurred. I am returning this unit in exchange for a replacement. In case of future failures with the replacement, how does one go about submitting a ticket? Thank you!
