I have an ArmyTek Wizard Pro CW 1300 Lumens Modded, and have a choice of 2 batteries, - AMPSPLUS 3500 10A or Sony VTC6 3000 15A.
does it make a difference, really?.
15A too much?.
any damage to the light?.
thanks.
Modded how?

no answer, but battery amperage is just what it can sustain, in terms of draw, From your light…
It isn’t what it “pushes” into the light…
IIRC
So if your light draws less than 10…AMPSPLUS
10-15, VTC6
MORE than 15? probably need some more firepower 
A battery is an electromotive force generator. Its output voltage and energy varies with load. Energy cells like the Ampsplus 3500 10A (a rewrapped Sanyo NCR18650GA) usually deliver more energy than higher discharge units like the Murata VTC6 at or near their maximum rating (at or near the max rating of the NCR18650GA which is noticeably less for the US18650VTC6). Given a constant discharge rate the output energy is ∫ V(I,C), being V the function of the output voltage of the cell at a given discharge rate for the delivered capacity C between maximum and minimum (cut-off) voltages.
Sorry if this sounds a tad confusing. I'd like to say, though, that usually running a cell near its specified maximum current ratings is stressful and so I'd prefer and choose a higher discharge rate cell once the square of our target average discharge rate meets or surpasses the square of the cell's maximum rate. In the case of the NCR18650GA this means I'd choose a higher discharge cell for average ratios higher than 7A. 
Cheers ^:)
The Olight HDC cells are also rewrapped Sanyo NCR18650GA cells , So you have another option. They are protected and not cheap though. I would go with the Sony VTC6 or a Samsung 30Q if it will work. I had a married set of the Olight HDC cells for an X7, but one of them is no longer good so I broke them up and have them in other lights. Also they are made in China.
