RE: lipo battery
I agree with RCKen, I've never had nor seen a lipo explode. It just doesn't happen. You can't go wrong with more mAh's unless the battery weight exceeds the lift potential of the model.
Overcharging or using a "swollen" Lipo will cause a puff of smoke or even fire. However; THEYDON"T #^@#^& EXPLODE!
