First of all, you calculate based on the
batteries stated 'C' rating:
(C rating X (mAh ÷ 1000) = amps / example: C5 X (2000 ÷ 1000) = 10 amps)
Or, the stated "high-drain" maximum amp output (if so labeled) - which in some cases is indicated in both a short time span and a continuous load. If this information is not known, then you can deduce from the charge capacity an approximate, and logically conservative, safe rate.
Using the
linked chart (produced by
steam turbine based on information gathered from and collected by
baditude and other sources) - the most common 2000mAh capacity battery (that isn't over-inflated by the mfg) is 10a.
As I don't recognize the battery label, and you've hidden any potentially useful label information from view
(When asking mech/RBA questions, please provide
all pertinent information available to you -
especially battery and resistance data), I must guess as to manufacture (these Chinese "kit batteries" are the cheapest of the cheap and frequently relabeled to hide their origins) - I'd think about calling it more a 7-8 amp rating. Safety first eh?
Now... we go to our
ohms law calculator (one of hundreds found on the interweb... but I'm fond of this one), punch in our fully charged battery voltage, which should be very close to 4.2v or a bit less If you don't know this, then you don't have a DMM - If you don't have a DMM... you need one, and perhaps for convenience as well as safety, an ohm "build box".
So - 4.2v - 10a max continuous discharge - 0.42Ω is your absolute minimum resistance value - which if you review the chart for battery/resistance applications - lines up, as it should, on the conservative side. Until you become more battery and coil knowledgeable, stay conservative - stay safe.
As you are new to mech mods and rebuildables, I"ll also point you to a
list of useful information - where the above, being very useful links, are repeated. I'd suggest starting with a single 1.0 ohm coil, and working your way down as you learn. If your atty is capable of dual coils, then two 2.0Ω coils (gross), for a 1.0Ω net resistance.
Cheers
