Will either of them have a effect on performance

[Smokie]

Does anyone know if there is any difference of using 3.7 Volt, un protective, or protective battery's in my SD? I know that there is a circuit in the protective one that will stop under draining, and over charging, but Will either of them have a effect on performance of the SD in any way?

They shouldn't Smokie.
The only change is in the charge and discharge limits of the cell.

Unprotected may give a little more milli-amps but not worth it in my opinion, there are some dangers with unprotected cells that can be solved for less than a buck by buying protected cells.

Some of the dangers of unprotected cells:

Potential Dangers
Despite the aforementioned advances in electrochemical structure, Lithium-Ion batteries remain inherently intolerant of overcharge, over-discharge and high current abuse, and all reputable batteries contain electronic protection circuits that are designed to protect both the battery and the user if these conditions are brought about.

Overcharge
The target charging voltage of a Lithium-Ion cell is 4.2V +/- 0.05V per cell, and the protection circuits should prevent charging above the specified safe voltage. Consistent overcharging can cause the plating of metallic Lithium within the cell. Bringing metallic Lithium back into the equation will cause instability, especially if the cell is of lower manufactured quality, and especially if any moisture has been introduced inadvertently during the production stage.

Over-discharge
Over discharging can cause copper plating that leads to internal shorting within the cell. The protection circuits should stop discharge well before the battery gets below 2.5V per cell. A well-designed battery would permanently disconnect if a voltage below 1.5V is observed by the protection circuit.

High current abuse
If the battery is discharged at an excessive rate, the excessive transition of Ions can bring about a breakdown in the crystalline-layered structure of the plates of a cobalt oxide Lithium-Ion cell. This can lead to a sudden rise in temperature that could possibly ignite the organic solvent of the electrolyte (which will not self extinguish).
