Do you know which brand it is? I didn't even know 5000mAh 18650s were available.
Skipping to 1:58, the chart shown suggests that higher valued mahs are ideal for low watts, and lower mahs are better for higher watts. It also suggests that lower amps are better for low wattage usage. Like everyone, I would recommend a good brand such as LG, Samsung, Sony, etc. And there is no official battery which are more than 30amps.
