Frequently Asked Questions

• Is this transmitter battery suitable for my Graupner RC transmitter? — Yes, this Gens Ace 1S HV 6900mAh pack is specifically listed as compatible with popular Graupner transmitter models including the MX10, MX12, MX16, and MX20. The universal JR connector also makes it compatible with most other RC transmitter brands available in the UK market. If you're uncertain about compatibility with your specific transmitter model, the JR connector is the industry standard and works with the vast majority of modern RC radio systems.
• How long does this battery last on a single charge? — The 6900mAh capacity provides exceptional runtime for transmitter use. Actual operating time depends on your specific transmitter model, usage patterns, and control intensity, but this large capacity ensures you can typically enjoy many hours of operation between charges. This makes it ideal for full-day events or situations where you're operating multiple RC models in succession.
• What does 1S HV mean and why does it matter? — 1S refers to a single-cell LiPo configuration, providing 3.8V nominal output. HV stands for High-Voltage, indicating this battery uses high-voltage chemistry that delivers enhanced performance compared to standard 3.7V packs. The high-voltage formulation provides better discharge characteristics, more stable voltage delivery, and improved overall performance in your transmitter, resulting in more reliable control signals throughout the battery's discharge cycle.
• Is this a high-voltage LiPo and how does that affect charging? — Yes, this is a high-voltage LiPo pack that operates at 3.8V nominal. High-voltage LiPo batteries can be charged using standard LiPo chargers set to normal charging protocols, though some advanced chargers offer HV-specific charging modes that can optimise the battery's performance and lifespan. Always consult your charger's manual to ensure it supports HV LiPo charging, as charging a high-voltage battery incorrectly could damage the pack.
• What is the difference between this 1S2P pack and a standard 1S LiPo? — The 1S2P configuration indicates two parallel cell strings in a single series arrangement, which provides superior discharge performance and more stable voltage delivery compared to simpler single-cell designs. This configuration allows the battery to deliver consistent current without excessive voltage sag, ensuring your transmitter maintains reliable performance throughout the entire discharge cycle. The parallel arrangement also contributes to the exceptional 6900mAh capacity whilst maintaining the compact form factor.
• How much does this transmitter battery weigh? — At just 122 grams, this battery pack is lightweight enough for comfortable all-day transmitter operation without causing hand fatigue.
