Yes, that should work well - especially with the large number of gel packs toss in the bag after the washing machine. Yes, fine business. :-)
The capsule should be fine - they work well - BUT you may need to pay attention to the bias voltage level ... ask the experts whether the cheaper Chinese capsules can run at the higher voltage produced by RODE boards. Otherwise OK.
And, I have used various edge terminated capsules from Chinese vendors on eBay.com with satisfying results -but I realize your mileage may vary - check the voltage levels in any case.
Just my take. James
