8S LiPo & LiHV Batteries

This category covers high-voltage 8S (8 cells in series) LiPo and LiHV batteries, delivering a nominal voltage of 29.6V (LiPo) or approx. 30.4V (LiHV). Fully charged, they reach approx. 33.6V or 34.8V (for LiHV) respectively. These are packs intended for specialized applications requiring very high power and efficiency.

8S batteries (LiPo and LiHV) are mainly used in:

• Large RC airplanes and helicopters: Where immense power and long runtime are needed.
• Heavy-Lift multirotors: Professional cinematography platforms (carrying heavy cameras), agricultural drones, inspection and industrial drones.
• High-performance, large RC boats and cars.
• Rarely in typical 5-7 inch FPV drones, due to component limitations and weight.

The advantage of such high voltage is the ability to achieve very high power output at relatively lower currents compared to 4S or 6S systems, which can translate to high efficiency in large, optimized powertrains. Capacities are usually large (3000mAh - 10000mAh+). High-current connectors (XT90, AS150, QS8) are required, and the balance connector is a 9-pin JST-XH. LiHV versions require a compatible charger. We offer 8S packs from brands specializing in high performance like GensAce/Tattu.

Choosing an 8S battery is a decision made in the context of advanced, high-voltage projects. Pay special attention to:

• Component Voltage Compatibility: This is absolutely fundamental! Double-check without fail that the ESCs, motors (with very low KV ratings), flight controller, and other devices are explicitly certified for 8S operation (max approx. 34-35V). Standard FPV components (even those rated for 6S) will be instantly destroyed!
• Cell Type (LiPo vs LiHV): 8S LiHV versions (charging to approx. 34.8V) are rarer, but if they exist and you choose them, they require an LiHV charger and components tolerant of the even higher peak voltage.
• Capacity (mAh): Selected based on the large model's requirements for flight time/endurance and payload. Usually values from 3000mAh upwards.
• Discharge Rate (C rating): Although the current for the same power is lower than at 4S/6S, the total power and peak currents in 8S systems can be very high. Choose a 'C' rating appropriate for the maximum demand of the motors.
• High-Current Connector: Connectors capable of safely handling high currents are required, such as XT90, or in extreme cases AS150 or QS8.
• Weight and Dimensions: Still important in large models for payload capacity and flight characteristics.
• HV Component Availability: Remember that ESCs and motors rated for 8S+ operation are less common and often more expensive than standard 4S/6S components.

8S power is the domain of advanced users and specialized builds.

Safety when handling LiPo/LiHV batteries is absolutely paramount! Improper handling poses a real fire risk, especially with high voltages like 8S. Always follow these rules:

• Charging: ALWAYS use a microprocessor charger designed for LiPo/LiHV with balancing function (balancing is mandatory for 8S!). 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=8, 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 using telemetry or other systems. Land/stop operation 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 an appropriate resistor/discharger 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 8S LiPo or LiHV batteries, please contact us. Due to the high energy of these packs, extreme caution is highly advised. We also offer special LiPo Safe bags.
