02 / ENGINEERING SELECTION
Evaluate the cell
within your battery design.
Size, mass and cycle duty
The 10.7 × 74 × 172mm envelope and 313g listed weight are selection inputs. Review the ≥1,000-cycle value at 80% SOH against the intended cycle duty and complete battery-system design.
UAV battery-system evaluation
Use the aircraft voltage, load profile, mass budget, installation space and environment to evaluate this cell. A specific aircraft or device requires its own system-level validation.
