Bararontok said:It says in this source that the membrane potential is a voltage and that the cells function as batteries.
Whenever you cite a source please mention exactly where the statement that supports your claim, lies.
Bararontok said:Because what is potential but a difference in charge that allows electrons from a region of higher voltage to migrate to a region of lower voltage?

These other sources also say that the sensory receptors convert the input energy of the stimuli into electrical impulses.

Just like mtc1973 said, energy from the stimulus is used as an ignition after which the energy used to carry signal forward is given by ATP; just like an engine where the combustion is started by a small spark which can be said to transfer energy bu to keep the combustion going on you need fuel.
