2 battery's in parallel
 

I have 2 entherlands 14.8 volt 4s 3200 mah lipo's ,can i run them in parallel
to make 6400 mah? I wil be useing this in a losi 8t 2.0 truggy,wil i have
enough continuiois amps to run a cool set up ,oh by the way they are both
30c packs and i am useing a mmm with a castle 2200 motor.I think the 2200
runs at 120 amps,will these two battery's be enough? I know i can run one
pack with a high mah, but they can cost some big bucks.What 2 small packs
can i run together that are low in price.Thanks.

As long as they are exactly the same batt and about the same # of cycles and balanced together. The one big pain will be charging and balancing two batts. Its easier to worry about one batt.

I'm not sure that two small batts is cheaper than one lg one.. maybe under certain circumstances.
