Minor Taser recharger racks can take more than 3, but will turn invisible.

[Avack]

Taser recharger racks have a stated capacity of three tasers. However, it is possible to put in more - I tested successfully up to six - but this will cause the rack to turn invisible, presumably due to a lack of sprites. While invisible, it still exists and can be interacted with via ctrl+alt+shift+click.
