If you want 80A continuous then those “15C” and “12C” packs aren’t going to work well.
Try to find a “50C” or “80C” pack
C means “per hour” so for example 20Ah times 12C equals 240A
The only problem is that manufacturers severely exaggerate these numbers as a marketing gimmick. You can probably divide by 5.25 to get “actual usability” numbers, so that would mean 22.8A per motor on that pack
If you bought ten of those 6S 12C packs and connected them 5P for a total of 12S5P then you’d have a 12S 100000mAh pack that can do 228A, but it’d cost way too much and be way too heavy
