The max load of J-10A in this case is not important, since you are not going to use it in a role that will make use of that. When you are going up for air combat, you don't want to carry too much armament since that decreases your maneuverability and increases radar signature.
And J-10 doesn't necessarily loose out to flankers in BVR. Although it is considered to be in F-16's weight class, it actually has a fairly large nose (around 74 cm like J-8II), compare that to 96 cm of flankers. Sure, its radar and processing power is weaker, but it also has a much much smaller radar signature than flankers.
