Pendulum with Magnets (All opposing)

[Magluvin]

One reason that there are 2 magnets on each lever at the top is to counter balance the weight of the slide plate magnets. The lever at the top is not center, so it looks as if to need the extra weight to reduce the amount of force to lift the plates, considering where the fulcrum center is on each lever.

Thanks for your excellent pictorial analysis. I asked many of the same questions.
However the simplicity appeals to me.
The biggest question you raised in my opinion is the magnet in the slide we assume repels, and you rightly point out that its force must be greater than the force it provides (the kick) otherwise it would not go all the way down. However it does travel at a fair velocity so perhaps the momentum is enough to overcome the repelling force.
The other theory is that it is not in repulsion at all and it orientated to pull the pendulum towards it with the repulsion magnet at the top providing enough repulsion to overcome the attraction. That doesn't make sense but without further information we can only speculate.

Not saying it IS a battery/coil, just pointing out two ways it might be fudged.

sorry, if i stepped on your feet 
but my english writing and grammar is not good enought. i also understood it the way that you're just give a possible place for batteries.
