I imagine that the amentum wraps round the javelin. The force of the throw causes the javelin to spin and the triboelectric effect causes the javelin to become charge. When the javelin reaches its target, it discharges, causing death by heart failure.

There is no real world way to do this by creating static charge from the triboelectric effect.

You can't put sufficient charge on a javelin that it could ever do any damage. Electric machines used the triboelectric effect (ie rubbing) to separate charges. The voltage that can be obtained this way is quite high, but the actual amount of charge, and hence the amount of current that can be achieved is very low.

We can't achieve sufficient charge using any kind of rubbing. If we want deadly levels of electricity we either need Tesla coils or an AC generator (and an electric chair).

If you did somehow manage to charge the javelin up, it would rapidly discharge out the pointed end before it reached any hostiles.

We can't create anything that approaches a lightning bolt, even with our most power generators and tesla coils. The powers required are beyond us. If you want death from lightning, first give your giants weather control skills.

What we can make is an electric "cattle prod" and the tech to make these is fairly low: a battery, some transformers a few wires. It has been suggested that the Ancient Greeks used a very simple electrical cell in some temples, so it is not inconceivable that your giants could have developed "cattle prods", and it is only a short step from a cattle prod to a taser.
