About how many flights could I get out of 2 2300s or 2 1100s before needing a recharge. With the most extreme flying situation. I would like to be able to fly all day or atleast 12 to 14 flights without a recharge. Where I fly I do not have to wait my turn because I am the only person there, besides my 2 sons. So it will be back to back flights with maybe just a couple of minutes inbetween flights to check everything over. The less I have to charge batteries the happier I am. Sorry TOM but I cannot find any that have 2500mah. I read somewhere that if they are anything other than 1100 or 2300 then they are not the real deal. But I am the novice here so I can't say that is a fact.
