different size battery

[dewser]

I just got a striker spy drone so I can learn without spending a lot of money right away.My question is I have a 3.7v 850mAh battery now.Can I go bigger on the battery size for more flight time

Yes, Stay with the same voltage but get one that's higher mAh, say 1000. There's a penalty for added weight so you cant go to big.

Usually, it use 500mAh 3.7V Battery.
