Hey guys if an 11.1v lipo is too much use a 7.4v lipo, it will be 8.4v when it is fully charged and it flows more current so let's say you have a 9.6v mini batt. And you want lipo a 2 cell lipo will in most cases give you the same or more bps , you ask how dose a lower voltage batt give the same or better performance? Good question . The rate of fire is controled by the voltage you send the motor a mini batt. has small cells that have hi internal restance witch when you put a load on them , in our case 10-20 amps the voltage drops because the batt has such high restance so maybe your 9.6v mini bat when you shoot may drop to 7v on a good one ormaybe 5v on a cheap one. Where a good lipo
may be able to handle 40-50 amps current. So when you fire your gun on a 2cell lipo the voltage will stay at about 7.5-8v so your gun keeps a good fire rate. Now the second benifit is a lipo is much higher capacity for the same size as a mini batt so let say you have a 1200mah mini bat if you use a lipo you may be able go as high as 2200 mah for the same size if you have a little more room you may go higher mah it depends on your gun. Another advantage is a lipo charges faster no more 5hr charges , a lipo will charge in 1hr and the batt in most cases will weigh less. So the only down side is you need a special charger to charge them and you can not run them all the way dead. From my experience I have found that a lipo will give you about 1.5-2 round fired per mah of batt. power , example a 4000mah lipo like I use in my gun gives me at least 6000rounds fired before I have to charge. So don't be afraid of lipos just use the right voltage for your gun. Bob.
