RC Discharger’s Regenerative Discharger 4S (2 x 2S) version 2: A Revolution in Battery Management

Are you tired of conventional battery dischargers that limit your charging capabilities? Look no further! The RC Discharger’s Regenerative Discharger is here to transform your RC battery experience. Let’s dive into the exciting features of this groundbreaking product:

  • Compatibility Beyond Limits: Our Regenerative Discharger is the first-ever battery discharger compatible with all Junsi iCharger models, including the 456DUO, 458DUO, 4512DUO, 406DUO, 308DUO, 4010DUO, DX6, DX8, DX12, S6, X6, X8, and X12. Whether you’re a professional or seasoned pilot or a hobbyist, this compatibility ensures seamless integration with your existing setup.
  • Dual Charging Power: Don’t lose one output for a resistor bank, imagine cycling, discharging and/or charging two batteries 2S simultaneously up to 45A using both outputs at the same time on your iCharger DUO. Does the work of 2 resistance banks with 2 iCharger DUO. The RC Regenerative Discharger makes this dream a reality.
  • Synchronous Mode Advantage: Unlike any other discharger, ours is compatible with the Synchronous mode of your iCharger DUO, allowing you to discharge a battery 2S up to 70A. Say goodbye to limitations and hello to unprecedented power management.
  • All-in-One Solution: No need for a second device to test and compare your batteries’ capacity and internal resistance. With Regenerative technology, you’ll achieve a lower internal resistor compared to a traditional resistor bank.
  • Internal Resistance Reduction: At 30A/32A/40A/45A/50A/70A cycles, our discharger significantly reduces your battery’s internal resistance. The result? More speed, power and longer battery life. Check out our test videos for proof!
  • Be eco-responsible: Are you tired of replacing your RC batteries every six months? Consider this eco-friendly alternative: cycle management. By optimizing your battery usage, you can significantly prolong their lifespan while minimizing waste.
  • Eco-Friendly Energy Recovery: Our product doesn’t just discharge; it’s environmentally conscious. It recovers energy during discharge and reuses it during charging. Efficiency meets sustainability!
  • Space-Saving All-in-One Design: Our clean and neat design features short wires and optimizes space. It holds both the charger and power supply, streamlining your setup.
  • No Resistor Banks, No Hassle: Forget about disconnecting resistor banks after discharge. Our discharger works seamlessly with the Cycle mode on your iCharger S6/X6/X8/X12. No fuss, no resistors, and no excessive heat.
  • Ready to Use, Plug-and-Play: Simply plug your iCharger into our RC Regenerative Discharger, and you’re good to go. No complicated setup—just efficiency at your fingertips.

Get ready to revolutionize your RC battery management with the RC Discharger’s Regenerative Discharger. Power up, sustainably!

Regenerative Discharger usage directions and specifications:

  • Cycle Mode: Utilize only the “Cycle” mode on your charger. This mode automatically discharges and then charges your battery. It helps maintain battery health and balancing cell voltages.
  • Storage Mode: At the end of the day, switch to the “storage” mode. This mode maintains the battery at an optimal voltage level for storage. It’s especially useful when you won’t be using the battery for an extended period.
  • Single Battery Per Car: For optimal performance, dedicate one battery per car. Avoid alternating between multiple batteries. This consistency helps maintain balanced cell voltages and extends battery life.
  • Avoid Excessive Discharge: Do not use several times in a row the “Discharge” mode from your charger.
