Lithium Ion w/regulators.
+1
I use two 5200 mah packs in a 35%er. I fly 4 flights in one day and go back to the field and fly 4 more the next day and still have power for a few more flights. Grant you I am not a tear it up heavy duty 3D guy. I can also check the battery at the field and know exactly when I need to charge. I will charge the batteries and go flying a month later and have enough power in the batteries to fly with no worries due to the very slow self discharge rate. I got Lithium Ions because I hated charging at the field when we were all using MiMH's. Can't understand why there is such an issue in some hobbyists about using a regulator. Seems 123's became popular when the Lithium Ions were hard to get due to factory issues in China a few years back and guys started tearing up drill packs. I see too many guys posting on the flying sites about their wrecks and seeing 123's listed as part of their equipment. Still can't figure out the advantage of 123's but the old saying goes "to each his own".
