The LiPower 11.1V 3500mAh 3S 60C Lipo Battery XT60 Plug is a high-discharge, premium lithium-polymer rechargeable battery pack engineered to deliver burst and continuous current for high-demand RC models, multirotor drones, aerial photography UAVs, and mobile robotics platforms. Configured in a 3-Series (3S1P) cell arrangement with a nominal voltage of 11.1V (12.6V fully charged), it features a high-rate continuous discharge rating of 60C (delivering up to 210A continuous output) with burst capability up to 120C. Terminated with heavy-duty 12 AWG high-strand silicone leads, a factory-soldered genuine XT60 high-current connector, and a standard JST-XH balance lead, this battery pack combines high energy density with low internal resistance to eliminate voltage sag during aggressive full-throttle maneuvers.

• UGV & Mobile Robotics Platforms: Providing an 11.1V high-capacity DC power bus for heavy-payload 4WD/6WD rovers, quadruped robots, and multi-axis robotic arms.
• High-Power DIY Electronics: Portable power source for high-output LED searchlights, mobile inverter systems, field radio communication rigs, and high-torque DC linear actuators.
• Airsoft Electronic Guns (AEG): High-capacity external battery stock configurations for upgraded, high-rate-of-fire custom airsoft builds.

Usage Tips

• Balance Charging Requirement (CRITICAL):
  • Always charge this battery using a dedicated microprocessor-controlled LiPo balance charger (such as an IMAX B6 or equivalent) via the JST-XH balance port.
  • Never charge using a simple non-balancing DC power supply. Balance charging ensures each individual cell tops out at exactly 4.20V (±0.01V), preventing individual cell overcharging which can cause thermal runaway and fire.
• Discharge Cutoff & Over-Discharge Prevention:
  • Never allow individual cell voltage to fall below 3.0V (9.0V total pack voltage) under any circumstances.
  • Set your speed controller (ESC) low-voltage cutoff (LVC) or telemetry alarm to 3.4V to 3.5V per cell (10.2V to 10.5V total). Over-discharging permanently destroys cell chemistry, spikes internal resistance, and causes irreversible cell swelling ("puffing").
• Safe Storage Voltage Protocol:
  • If the battery will not be used within 48 to 72 hours, put the pack into "Storage Mode" using your balance charger, setting it to 3.80V to 3.85V per cell (~11.4V to 11.55V total).
  • Storing a LiPo fully charged (4.20V/cell) or fully depleted (≤3.5V/cell) for more than a few days triggers internal chemical degradation, rapid capacity loss, and pouch expansion.
• Charging Safety Guidelines:
  • Always charge the battery inside a certified fireproof LiPo Safe Charging Bag placed on a non-flammable concrete or ceramic surface away from wood, carpeting, or paper.
  • Never leave charging LiPo batteries unattended. Disconnect immediately if the pack swells, emits smoke, or becomes hot to the touch (>45°C).
• Physical Handling & Inspection: Regularly inspect the battery for punctures, dented corners, frayed wiring, or cell bloating. If a pack is swollen or physically damaged after a high-impact crash, do not attempt to recharge it; discharge it completely in an outdoor saltwater bath before safe disposal.
