I'm not familiar with which J3 you are talking about. I also am not sure what you mean by "stronger."

If you want a battery that will permit longer flights, then a battery of the same voltage as the stock battery but with a greater capacity (mAh) is what you want. The only question is whether the extra weight of a higher-capacity battery might be too much for the plane to carry.

If you are looking for a battery to make the plane fly faster, you could get a battery with a higher voltage than the stock battery. BUT that is very risky. If the motor and speed controller are not design to work with a higher voltage, you could permanently damage both of them.

Someone who is familar with your plane might know if it can survive a higher-voltage battery. Until you know for sure, I would not recommend it.
