This is opportune time to make a new half life . The first two broke new ground for games . 1 no backstory , decent puzzles in a shooter , no guidance . 2 real ish physics , grav gun . Now we have vr . Bring your new ideas valve . <| sep |> Less than $ 30 , still safer than AA size IMR . Nobody said anything was going to explode , in fact several people said IMR or INR in a BIGGER , more POWERFUL cell size was acceptable . What you will get if you persist in trying to get an AA size cell to do EVERYTHING is shitty duration , short cell life and you DO increase the chance of a cell failure especially when charging , as you are effectively red lining the cells on a regular basis . The ONLY use for AA SIZE IMR is as a drop in 2 or less in blasters DESIGNED FOR AA CELLS , any 2 motor semi , with the thermosistor STILL IN or 3 in stock motor 2 motor set ups if people want to keep the tray or alkaleak functionality . These are both good mods for kids , which many of us recommend often . What we don ' t recommend is UNSAFE PRACTICE , which is using them beyond their DESIGNED AND RECOMMENDED LIMITS . I am one of the first people to advocate the use of IMR chemistry in nerf , I would only recommend or use them for the above mods . Post dated Jun 2013 to back that up . highlight
