Been running electric a couple years now. Still have a lot to learn. A question that always enters my mind is, what setups require lower than 5,000 mah. I have always used those numbers in my boats and will be running 10,000 in my latest build. Who uses lower than 5,000 mah batteries, and why?

I do.
I race to Naviga rules which dictate a <280g for 2s/3s packs and <560g for 4s/6s packs. I chose to run 3s and 6s to lower the amp draws and gain a touch of efficiency through lower wiring losses so my full size race packs are low C rate 4000-4800mAh. If I wasn't confined by the rules I would probably run sturdier high C 4000mAh and have less runtime but longer battery life, as being designed around a 280g/560g battery half my boats won't fit a high C 5000 3s/6s pack, and I don't want to go back to the higher amp draws of 2s/4s.
For mini boats (450mm/17.5") 5000mAh is way to big and heavy, I run 1500 or 2000mAh depending on whos rules I am running to. Naviga are <110g which I have 1500-1700mAh packs for, and my old local club allowed <140g which gave me 1800-2000mAh. If I wasn't confined by rules I would probably run 2200mAh which are ubiquitous for parkfliers, so are cheap and easily available locally.Paul Upton-Taylor, Greased Weasel Racing.Comment

That is pretty light for a high C pack, but for 4s Tenshock have 7200mAh <560g, even with the extra voltage from a high c pack I think I would need >6000mAh to be competitive.Paul Upton-Taylor, Greased Weasel Racing.Comment
