I DID change adjust some of the settings, and when I did, my throttle was reversed for some reason, so when activated the throttle, throttled up to nearly 80%, i noticed something was off, so i promptly unplugged the batteries.

Brand new batteries, they are in good condition. I actually flew the plane earlier in the day now serious issues. When a lithium-ion battery is turned on, positively charged particles of lithium (ions) move through the electrolyte from the anode to the cathode. Chemical reactions occur that generate electrons and convert stored chemical energy in the battery to electrical current. Was it a bad soldering job to start with, or did it de-solder due to too high a ripple current caused by long battery wires? The lab’s research spans every aspect of battery development, from the breakthrough fundamental science of the Argonne-led Joint Center for Energy Storage Research, a DOEEnergy Innovation Hub, to the Argonne Collaborative Center for Energy Storage Science, a cross-lab collective of scientists and engineers that solves complex battery problems through multidisciplinary research. If you cannot but extend, extend the motorwires instead of batterywires and keep controller(s) close to battery(s). No need for extra input capacitorsA watt-meter will more than pay for itself, several times over, your battery, ESC and motor will love you for it. If you don't have the manual you'll have to use your google-fu and find it. With a little time you can usually find something that will help. Hyperion Emeter II wattmeter with local&remote logging, optical&electrical tach, servo tester - RCG Argonne is recognized as a global leader in battery science and technology. Over the past sixty years, the lab’s pivotal discoveries have strengthened the U.S. battery manufacturing industry, aided the transition of the U.S. automotive fleet toward plug-in hybrid and electric vehicles, and enabled greater use of renewable energy, such as wind and solar power.

Could you have accidentally entered programming mode then changed something in the ESC when you powered up with the throttle reversed?Argonne researchers are also exploring how to accelerate the recycling of lithium-ion batteries through the DOE’s ReCell Center, a collaboration led by Argonne that includes the National Renewable Energy Laboratory, Oak Ridge National Laboratory, as well as Worcester Polytechnic Institute, University of California at San Diego and Michigan Technological University.
