The Tinyhawk 1S LiPo battery is also part of the whole design around the great flight performance of the Tinyhawk series. The weight, the size, and the power from the High Voltage 450mAh capacity cell were all considered during the design processes. Our pilots agree that at least 4-6 batteries will be required to have the best flying experience for an all day fun fly. Voltage: 1S 4.35V HV, 3.80V Nominal Capacity: 450 mAh Discharge rating: 80C/160C Required Charger: Any charger that has 4.35 High Voltage capabilities and PH2.0 connector or the EMAX USB charger. EMAX Tinyhawk 1S HV 450mAh LiPo Battery — PH2.0 Connector This isn't just any 1S battery — it's the cell EMAX engineered specifically around the Tinyhawk's power system. Every detail, from the 450mAh capacity to the High Voltage 4.35V rating and the lightweight cell chemistry, was chosen to maximize flight time and performance on the Tinyhawk platform. Running the matched battery means you're getting the full 4 minutes of flight time the Tinyhawk was designed to deliver, not a compromised experience from a generic cell. 1S 4.35V High Voltage chemistry — more energy density than standard 4.2V cells for longer, more consistent flight 450mAh capacity — matched to the Tinyhawk's power draw for optimal flight time 80C/160C discharge rating — handles the Tinyhawk's peak current demands without voltage sag PH2.0 connector — direct plug-in fit for all Tinyhawk series drones Lightweight cell design — weight was a core design consideration, keeping your Tinyhawk flying fast and agile Pick up 4–6 batteries for a full day of flying. Compatible with the EMAX USB HV charger and any charger with 4.35V HV capability and PH2.0 connector support.
