Why is my recording hissy?

Perhaps consider replacing the battery box with a pre-amp.

Can you recommend one that would work with my setup? (see first post)

I used to rely on Church Audio preamps but it's not clear from their website whether or not Chris Church is still making them. I always had good success with the 9200 model, so you might want to look for a used one. If not, this Sound Professionals preamp might be a good alternative. https://soundprofessionals.com/product/SP-PREAMP/

The riot box would probably be a good solution too.  And is smaller than many battery boxes
