Thats why I asked about a better battery, not a bigger battery. The Kinetik HC2400 does what, 2600 burst amps? The XS Power D3100 does 5000 burst amps and it's the same size as the HC2400, so it still fits within the 800 cu in rules. The HC2400 is 740 cu in, the XS D3100 is 756 cu in, Thats twice as many amps when you need it in roughly the same size battery.
