More battery talk, just skip it if you're not interested. I'm not trying to make you folks read boring techi-talk...
LD, I'm have not seen any specs on the EH but the Efest should be fine. After I learned a little bit about batteries when I had my Vmax I'll only use AW's or Efest's, not saying other batteries are not as good but those 2 I checked out pretty good.
What he said ^^^^. EH are not bad batteries, at least their IMR batteries are for real. As to the fuses, I can only give accurate info on what I own, the ShortStop. It's important to know that the ShortStop kicks in at 5 amps, cutting off continuity. Using Ohm's law will tell you if the coil resistance is too low for the ShortStop. 4.2 volts at 5 amps allows for a 0.84 ohm coil at the lowest. Another important factor when using the Ohm's law calculator is that your Lithium battery should be 4.2 volts when fully charged. Input 4.2 for voltage into the calculator along with at least one other known variable (ohms, watts, or amps). The 3.6 or 3.7 volts that Lithium batteries are rated at is a general voltage rating and you can almost ignore that for these purposes. Playing with the calculator a bit will give you an idea of why APVs have low ohm limitations, mostly due to the max amperage the circuitry can handle. PWM and other boost circuitry helps, but only so much.
These amp limitations are why folks want to use mechs for low ohm coils, it's often the only way it will work. At that point you better know the specs on your batteries and ohm's law, at a minimum. The
general rule for
guessing the amp limits of a Li-Mn (IMR) battery is Amp hours times 8, example: 2000mAh = 16 amps max, usually far less than that for continuous. This can obviously vary as some have different chemistry, allowing for higher amperage while sacrificing battery life (mAh) or higher battery life while sacrificing max continuous output. 20 and 30 Amp batteries exist, but they sacrifice mAh and you shouldn't need that anyways unless you are looking to go under the limits of a 10 amp battery... 0.42 ohms (crazy). It's nice when the amperage ratings are listed, but some vendors and even manufacturers won't give these details. The maximum
stated mAh that
I have come across for an IMR with a 10 amp continuous output rating is the Efest 2600 mAh IMR 18650 (which Ray sells at a very decent price). There are others that have a higher mAh rating, but they are usually hybrids and I'm trying to stick with pure Li-Mn batteries here.
I could be wrong... don't take my word for it!
