6S LiPo & LiHV Batteries

6S batteries (6 cells connected in series) are the current standard power source for most modern, high-performance 5-inch and larger FPV drones. They offer a nominal voltage of 22.2V (LiPo) or approx. 22.8V (LiHV), fully charging to approx. 25.2V or 26.1V (for LiHV) respectively. The higher voltage brings several advantages.

Why do FPV pilots choose 6S?

  • Higher Efficiency: For the same power output, higher voltage means lower current draw (P=V*I). This results in less loss in wires and components, potentially cooler ESC and motor operation, and often slightly longer flight times compared to 4S with a similar flying style.
  • More Power and Control: The power headroom available on 6S allows for more dynamic maneuvers and often gives a smoother throttle response feeling, especially when using appropriately matched low-KV motors.
  • Standard for Modern Builds: Most new FPV components (FCs, ESCs, motors) are designed and optimized for 6S power.

6S packs (LiPo and LiHV) are commonly used in:

  • 5-inch FPV Freestyle and Racing Drones: The dominant choice for maximum performance.
  • 6-7 inch Long Range and Cinematic Drones: Where efficiency and flight stability are key.
  • Larger RC Models: Airplanes, helicopters, high-speed cars and boats.

Typical capacities for 5-inch FPV drones are 1000mAh - 1500mAh (often slightly smaller than 4S for similar flight time and weight). The standard connector is XT60 (sometimes XT90 for very large packs), and the balance connector is a 7-pin JST-XH. LiHV versions requiring a compatible charger are available. We offer proven 6S packs from GensAce/Tattu and other leading brands.

Choosing a 6S battery requires careful matching to the rest of the drone's configuration:

  • Voltage Compatibility & Motor KV: This is critically important! Absolutely ensure that the FC, ESCs, motors, and other components are rated for 6S voltage (max approx. 25.2V for LiPo, approx. 26.1V for LiHV). Equally important, you must use motors with appropriately low KV ratings (e.g., 1700-1950KV for 5-inch). Connecting a 6S battery to high-KV motors (intended for 4S) will almost certainly destroy them!
  • Cell Type (LiPo vs LiHV): As with other formats, LiHV (charged to 4.35V/cell) might offer a slight power/runtime increase but requires a charger with LiHV mode and ensuring hardware tolerance for the slightly higher voltage.
  • Capacity (mAh): For 5-inch drones: 1000-1300mAh is a common choice for maximum agility in racing and aggressive freestyle. 1300-1500mAh or more works well for smoother flying or when flight time is a priority. Larger capacities are used for 6-7 inch drones.
  • Discharge Rate (C rating): Although the average current draw is lower than 4S (for the same power), peak demands remain high. Choose packs with a high C rating (e.g., 75C, 100C+) to ensure stable voltage and full power delivery in all situations.
  • Connector: The standard is XT60. For very high capacity/current applications (e.g., large planes/helis), XT90 might be used.
  • Weight and Dimensions: 6S packs are generally slightly heavier and larger than 4S packs of the same capacity. Check fitment on your frame.

6S batteries from GensAce/Tattu and other reputable manufacturers guarantee high performance for modern FPV drones.

Safety when handling LiPo/LiHV batteries is absolutely paramount! Improper handling poses a real fire risk. Always follow these rules:

  • Charging: ALWAYS use a microprocessor charger designed for LiPo/LiHV with balancing function (balancing is mandatory for 6S!). NEVER leave charging batteries unattended. Charge in a fire-resistant location (e.g., in a LiPo Safe bag, on a ceramic/metal surface). Never charge damaged, puffed, or deformed packs. Use correct charger settings (cell count=6, LiPo/LiHV type). Recommended charge rate is 1C unless the battery manufacturer explicitly allows higher.
  • Usage: Avoid over-discharging cells (generally don't go below 3.3V-3.5V per cell under load, resting voltage ~3.7V for LiPo, slightly higher for LiHV). Monitor battery voltage in OSD during flight. Land when voltage is low. Protect batteries from physical damage and punctures.
  • Storage: For longer storage (several days or more), charge/discharge LiPo/LiHV to storage voltage - approx. 3.80-3.85V per cell. Use the 'Storage' function on your charger. Store in a cool, dry place, ideally in a special LiPo Safe bag or ammo can. Do not store fully charged or fully discharged for long periods.
  • Disposal: Never throw LiPo/LiHV in regular trash! Discharge them fully (e.g., using a light bulb or charger's discharge function to a low voltage) and take them to a designated battery recycling facility.

If you have any doubts about the safe use of 6S LiPo or LiHV batteries, please contact us. We also offer special LiPo Safe bags (available in another category) to increase storage and transport safety.
