I was thinking about replacing the batteries with either LG-HG2 18650 batteries with a 20a discharge and 3000mAh capacity, or the Samsung 30Q 18650 batteries with basically the identical specs. (Samsung rates the 30Q as 15a, but testing shows that it handles 20a without breaking a sweat.) Anyone see any problems with doing this? This would make the DCB204 battery sled become a 6.0ah battery instead of the 4.0 stock. Also would give it a better discharge rate so the batteries won't overheat as quickly. Just asking if I'm correct in my assumptions and should carry-on with my battery upgrade. Any and all advice is welcome.
