I recently purchased a new engine with a 6V ignition battery pack. The inclosed instructions said to regulate the 6V to about 5.3V.

I've seen discussions referring to regulators, but have not the slightest idea where to purchase. I've not yet seen this specific item advertised. Or is disguised? Or do I just use a zener diode? Seems like this is a waste of battery capacity being converted to heat. I probably should just get a 4.8V pack, but an inquiring mind wants to know.

Thanks,
Roger
