I'm not bias, I want to be convinced otherwise.

AXi 4130/16 Gold:
Can Diameter: 2" (49.8mm)
Length: 2.6" (65.5mm)
Max 8s Lipo = ~30V (Rounding up)
Max Current: 60A/60s

So thats nearly 1800W surge.

Neu 1512 series lists max surge power for all of them at 2000W
They have length 2.4" and diameter 1.53"

Significantly smaller, yet higher surge power.

Even at the AXi's max efficiency constant current (listed as 40A) thats a hair under 1200W, and the 1512's are 1000W constant, and theyre much smaller.

Go to a similar sized Neu, like a 1915: 1.96" diameter, 2.25" long. Still smaller. Constant 1800W, peak 3600W, heaps more grunt, still smaller, and lighter too (14oz vs 14.4oz).
