BetaFPV Lava II 1S 680mAh 30C BT2.0 Battery

The BetaFPV Lava II 1S 680mAh is a high-capacity whoop battery designed for extended flight times in lightweight micro brushless drones. With 680mAh capacity, it delivers 30–50% more flight time than standard 450–520mAh packs while remaining light enough for 65–75mm whoop frames and toothpick builds running 0802–1103 motors.

Key features

• 680mAh capacity provides 3.5–5 minutes of flight time depending on throttle and frame weight

• BT2.0 connector offers lower resistance and secure latching compared to PH2.0, reducing voltage sag under load

• 30C continuous discharge rating handles aggressive throttle input on brushless whoop motors without excessive voltage drop

• Compact dimensions and sub-20g weight maintain agility in 65mm and 75mm whoop frames

Specifications

• Capacity: 680mAh

• Cell count: 1S (3.8V nominal HV LiPo)

• Discharge rating: 30C continuous

• Connector: BT2.0

• Energy: 2.6Wh

Compatible with BetaFPV Meteor65/75, Happymodel Mobula6/7, and similar brushless whoops that accept BT2.0 batteries. The higher capacity suits pilots flying indoors or in confined spaces where longer air time outweighs the small weight penalty.
