Mostly just further confirming what the other guys already said.
Yes to a battery box. Choice of 9v or 12v for those mics I can't comment on, but you can trust goodcooker's experience and advice.
A few comments on using bass roll-off in a battery box. None for me. I prefer to set levels as needed to capture the full frequency range, then EQ afterward as necessary. Each situation is somewhat different and that approach maximizes my chances of ending up with the full and well balanced sound I'm after. When adjusting the response of the recording afterward I don't typically default to using a high-pass filter anyway as it's something of a brute-force blunt tool. It has its place, but usually in individual channels to be mixed and not so much a stereo mix itself or a two channel stereo pair used directly on its own. Instead, adjusting the EQ curve to suit the content while listening provides a superior end result.. But that does require decent monitoring you can trust, or at least knowing how to interpret what you are hearing from monitoring you've leaned how not to trust without compensating for its deficiencies.
In contrast, the application of high-pass filtering afterward can be done without needing as much careful subjective listening as more subtle EQing, and is a popular choice for a lot of tapers.
Taking that one step farther, using bass roll-off in the battery box could be the right choice for someone interested in minimizing all work done afterward as much as possible. But in that case, determining if the bass roll-off is doing what you want to your satisfaction is going to be a subjective personal determination, based on listening to those specific mics through the specific battery box filtering in question, of the typical content you record..
tl;dr- The low-frequency response will be partly affected by the pickup pattern of the microphones - omnis tend to have a flatter and deeper bass response than directional mics - and by what the sound is like in the venue and your recording position, but will also be effected by other characteristics of the specific microphones in combination with the specifics of the roll-off filter. That's because in a battery box the filtering is passive. Interaction between the mics and roll-off filter together effect the low-frequency response through the filter. On the battery box side of things that includes the r/c values used in the high-pass filter. On the microphone side it includes the impedance of the mics in addition to their inherent low frequency response. And of course on top of all that is the question of how bassy the sound was at the recording position to begin with.
The decision on where and how to mange low-frequency response revolves around this trade off between easy convenience and more fine-tuned control.
