I have a 5in quad, looking for a chunky battery for some longer flights around 10-15 minutes... any recommendations?

Mamba F405 MK2

2306 2450kv 
5048 props <-- gonna get shallower bi-blade props soon [any recommendations?  ]
288 grams dry weight

2450kv is high for long flight time.

As far as battery packs, you can consider Li-ion. You have to keep your amp draw down because li-ion cannot discharge high amperage like lipo.

Just also want to clarify your term. AUW means with battery. Dry weight means without battery.
