I own a couple of HohmLife batteries. If you’re interested in sticking to MTL with 10-15 watts, there’s very little concern about the spec accuracies in those batteries. Their advertised “max amp” output is likely a pulse rating however. If I remember correctly, the Hohm Life batteries have roughly a 20 amp continuous discharge rating and would only really be of concern to you if you plan on vaping near 60 watts or above. You have plenty of head room, you should be perfectly fine.
In the future, try sticking to OEM batteries from (more) reliable vendors like IMR batteries, Liion, 18650batteries, and a few others if you’re interested in accurate battery specs. For the current wattage you are vaping at, you could presumably get a battery with a higher mAh value with still a lot of head room in terms of amp draw. Anything with a 7.5 or 10 amp continuous discharge rating would be just fine for 10-15 watts.
Remember, pulse ratings are fluff and they’re fake. Good of you to ask though, that’s awesome.
