Overdriving a H1 bulb with 4s A123 cells?

[A380]

Hi,

a friend gave me a cheap spotlight going on a 6v SLA battery and a H3 55w bulb. Battery was dead and tryed 3s A123 (9.8v no load), of course the bulb flashed.

Searching the forums, I read that H1 bulbs are axial so give a tighter spot.

Now, the question is, could I use a 12v 100w or 130w overdriving it with 4s A123 or go with only 3s?

Thanks.
