To operate receivers and servos with 7.4 LiPo batteries, install the optional heavy-duty 6.0V 5A Voltage Regulator. It easily fits with the battery in the radio box, and prevents damage to gear that should not be exposed to more than 5 volts.

I have used this regulator on my buggy for a season and a half so far without a hiccup, I have had a muchmore go bad on me on another and just orderd another one of these to replace it.
Lasted just 5 minutes and it was fried. Used it in a Losi 8ight 2.0 with a Protek 7.4V 2S Lipo and MKS servos.
Does it inform you when you need to charge your lipo somehow? My old one blinked when it was time to charge the lipo.
