    I'm still a little unsure on batteries

    I will be buying a mini star 50w from FT that uses 1 18650 battery. I will be using coils at no lower than 0.5 Ohms. the voltage for the mod is listed as 3.2-4.3V (3.7V typical) I wont be using the mod above 30W.

    How many amps does my battery need to have? I used the Ohms calculator and vaping a .5 coil @ 3.7 volts @ 30w it suggests I need 7.75 amps. If this is the case then a Samsung 18650 would be a good choice?

    Or am I totally wrong? I really want to make sure I buy a suitable & safe battery. Also Is it safer to use a dedicated 18650 charger vs the inbuilt charger on the mod? If so what is a cheap but safer charger?

    As always any help is much appreciated.

    As i said in the other post

    this site will give you details about batteries, ITS NOT INFALLIBLE. so check other sites as well.
    what you want to pay attention to is Amp limit headroom the higher the % the better the battery for you needs,
    if its in the -% using the battery at that level will likley result in damage to the mod and/or you

    Great using the calculator you provided above looks the the 25r will have + 62% headroom. Thanks again for all the help people I'm now locked in on the 25r.

    The thing to reemember is that NO battery is 100% without doubt safe Ive had two of those same batteries die on me in the last month and another member here has had one over heat. At the same time Ive seen people sub ohm on second hand lap top batts without a problem and read recently of a mobile phone battery over heating and burning a house down nothing is fool proof.
    Your buying good batteries but still treat them with respect.

    My biggest fear is that I might die and my missus will sell my vape gear for what I told her it cost
