A broad selection of Reedy LiPo batteries is now available to power servos and receivers, transmitters, and starter boxes. Worrying about battery life in long main events or consecutive bump-ups is a thing of the past. And turning over a hard-to-start nitro engine becomes much easier with a high-torque starter-box battery. To operate receivers and servos with 7.4 LiPo batteries, install the optional heavy-duty 5V 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. A new 1800mAh 7.4V battery specifically for Micro cars replaces 7.2V NiMH stick packs. Rated at 20C, it is capable of powering the very hottest 1:18 scale motors to incredible speeds.
