Product overview
The BETAFPV LAVA 1S 550mAh 75C Battery (4PCS) supplies four LiHV batteries for quadcopter propulsion. Each battery combines 550mAh capacity, 3.8V voltage and a 75C discharge rating with a BT2.0 connector. Its 68*15.5*6.7mm dimensions and 14g weight define the physical space and mass to accommodate during integration. Each battery stores 2.09Wh. The cell uses a Z-Folding Process, with a 5% energy density increase over winding construction at the same volume and a 0.2V higher discharge platform under equivalent loads.
Battery handling and charging limits are part of the integration requirements. Fully charge each new battery before use, using a charger designed for lithium polymer/Li-ion batteries, with the LiHV charging ceiling of 4.35V per cell observed. Charging requires supervision and separation from flammable or explosive materials. During operation, voltage must not fall below 3V per cell under load. Fully charged storage must not exceed 3 days; long-term storage requires 3.8V–3.9V. Deformed or swollen batteries must not be used.
