Good day!
I have seen, in other forums, that some peaple are concerned about the higher voltage of a lipo on there electronics. They are saying to use a voltage regulator to keep the voltage at 6. Any comentson this?
Thanks Neil.
Hi Neil,
Your Speed Controller will regulate the main battery voltage (whether it be old school 7.2V or new school 7.4V) down to 6.0V before it passes it along to your receiver. So, your receiver, servo, and personal transponder will only ever see 6.0V.
You might be talking about people using a separate 2-cell LiPo receiver battery pack to power their receiver. In this scenario, a separate small battery pack is connected directly to the receiver. Here it is probably advisable to use a 6V regulator unless you know that your receiver, servo(s), and personal transponder can handle the larger 7.4V supply.
For electric 7.4V racing, you should not need to worry about adding a regulator anywhere.
For gas racing we used to use a 5-cell NiMh receiver pack which gave 6.0V and was perfect. Now racers are using a 2-cell LiPo 7.4V receiver pack. Once again, it is probably advisable to use a 6V regulator here unless you know that your receiver, servos, and personal transponder can handle the larger 7.4V supply.

A couple dropping diodes will do the trick -- no need to use a full-fledged regulator (although a regulator isn't a bad idea).
AKA "BEC," or "Battery Eliminator Circuitry." Just a couple diodes in series to drop the voltage down a bit so it's in the safe range, mostly to stop your servos from self-destructing from too much power.
Some servos actually have a seperate power wire that you would connect to your 2-cell directly to use the extra juice.
