Tryin to get input on what might be the best way to upgrade my 510. I am rather new to this and I want to get a drip tip and maybe a lr 306. I only have a starter kit and i have read that I cant add a lr306 to my 510 w/o a stronger battery. when looking online the batteries they recommend look like standard batteries and I was wondering if I had to buy a complete new kit or could I incorporate it into what I already have? Thanks
