Tips Are Greatly Appreciated 💰 https://streamlabs.com/frankstechhelp/v2/tip - Please Support This Channel Franks RC Cars - You can find the before and after speed tests at the end of this video. It's amazing how much faster it is after the upgrade. In this video I show you how to upgrade the Dune Thunder 12891 to use a 7.4V 3000mAh external battery with a Deans "T" plug adapter. This method allows you to use the existing 18650 batteries or the Deans T plug on the fly. The 18650 batteries in this video are the unbranded stock batteries that come with the Dune Thunder and are 3.7V 1500mAh each. The extended battery is the Feiyue WLTOYS 7.4V 3000mAh 20 Amp battery with a Deans T plug tip. The 20 amp extended battery definitely puts some extra pep in the Dune Thunder's step! It's almost too fast to handle on sharp turns now. It's an amazingly fast improvement. Please note that you modify your RC Vehicle at your own risk and I am NOT responsible for any damage that you may cause to your own vehicle. Spanks ;)
