me and a friend of mine were having a discussion about batteries the other day because he asked me what batteries im using (sony vtc4) and then we started talking about rc cars (another hobby of ours) and we started thinking...would we be able to use rc car batteries for mods? im no battery expert but just a quick look up of some of these batteries i saw some that were like 8.4v 4500 mah etc (but they were in battery packs, i dont know if that was for a single battery or not). i doubt they have them in a 18650. anybody else thought of this or tried it? im not gonna try it so dont worry lol. ill stick with my sonys. im just curious
