Pretty much the title of the thread. These are the tooltips for the Chaos merged batteries:

So they either don't show the lance component, or the lance and battery component are not clearly separated.
Optimally the tooltip should read:
Macro battery: Number of attacks, damage, reload time, etc.
Lance battery: Number of attacks, damage, reload time, etc.

Otherwise it is not clear how the damage of this weapon works in different scenarios (ranges, holofields, armour, ...)
