So, about a year ago, I ordered a 35A 3000 mAh HG2 and really liked it. So, I ordered two more. Problem is, I did not pay attention to detail when I ordered them. These are 20A 3000 mAh. I have not used these, yet. I am concerned they are not strong enough for an SX Mini ML class running 316SS Klapton coils at 0.27-0.32 ohms of resistance, anywhere from 30 joules to 50 joules. I never go above that. Are these safe to run at these specifications? Thanks.
