In order to run a servo at a higher voltage the bec has to be able to supply the higher voltage. Check your esc manual. Secondly your servo has to be able to handle the higher higher voltage otherwise you risk the probability of burning it up. The advantages are a faster and stronger servo. Not everyone likes a fast servo. But more torque is always desired. The cap is there to prevent breakouts which happens when the esc demands more power then the battery can deliver. It will cause your car to act very erratically with issues like no steering or you won't be able to accelerate smoothly.
