A charge controller (or at least a voltage regulator of some sort) is necessary. A 12 W panel can easily overcharge batteries. Video. A 10 W panel isn't significantly different.
This is a perfect example of a self appointed Internet expert spreading false, although not dangerous in this case, information and other people helping him do it.
Although I agree that a simple regulator in the circuit is always a good idea, I do NOT AGREE that what is illustrated in the video constitutes any kind of real problem.
The 15.1 volts illustrated will only be present for about two hours of peak sunlight and the resulting 750 ma is NOT enough to do any damage to any kind of decent battery; especially not the bank of two 6 volters in series.
For about 22 hours a day the charge applied would be less than 15 volts and for something around 14 hours a day it would be near ZERO.
This is hardly anything to get excited about.
