Help: Swapping pickups in EBMM Stingray Guitar (not bass)

So I just picked up a 2017 Stingray (guitar, not a bass) for what I think is a great deal. This is a model with 2 humbuckers and the pickup switch on the opposite side of the volume and tone pots. I personally think the pickups need some more output for my playing style and was looking at replacing then with active EMGs.

I notice that there is no battery compartment for the active pickups. I’m wondering if anyone has swapped the stock pickups with actives in this particular guitar and if so, where did you put the battery?

If there’s no way to do this then I may just go for a SD 59/JB pair or something.
