I recently got back into airsoft after 8 years or so. I just got a G&G CM16 2.0 and upgraded to an m120 spring and shimmed the stock gears. Ive been researching LiPo's and Titan Li-Ion batteries. I like what I see with the Titan batteries compared to the 9.6v NiMH 1600's Ive been using. The gun is wired for Deans already but does not have Mosfet. If I am going to use a 7.4v 3000mAh Titan battery, will I need to install a Mosfet to not burn out my trigger contacts, etc?
