The cell limit for the Mamba Max is based on the Kv of the motors we include with the system, not the Mamba max ESC. Simply multipy the motor Kv by the pack voltage. If it is over 65,000 the motor will spin apart. With lower Kv motors the ESC has no problem with higher voltage, up to 5s lipo. The ESC is about a 100 amp ESC. 100 amps X 18.5 volts = 1850 watts. The issue is you must have batteries capable of 100 amps continuous output. Many battery companies C rating would lead you to believe they can do this, few deliver on the promise. We recommend having at lease 20% more battery capacity than you think you will need to avoid problems. Also only buy lipos from reputable companies, most of which are not common in the RC-Car world.

If you have adequate batteries you don't need extra capacitance and if you have inadequate batteries extra caps won't help you.

The amount of power it takes to move mass goes up by the square of the mass. While the Max system with a Max motor used withing spec is capable of 1000 watts (11.1 volts X 90 amps) and is capable, with a lower Kv motor and more voltage of about 1850 watts. However, this is not enough to move the weight of a Monster truck or 1/8th scale conversion reliably. In these systems the Mamba Max ESC is a $130 fuse. When you hit the throttle hard on a hot 1/10th scale the amps will spike over 500 amps. The spike with a heavier car is a potential ESC killer. Capacitance has no affect on these spikes. BTW, the amp spikes in our 1/18th scale systems are over 150!
