Product overview
The WES 22000mAh-8S1P LiHV supplies battery power for heavy logistics, long-distance industrial inspection and agricultural UAV operations on platforms carrying payloads of 15kg or more. Its single-module architecture connects eight LiHV cells in series, providing 30.8V nominal voltage and 677Wh of energy. The pack measures 83 × 92 × 205mm and weighs 3046g ±30g, making battery-compartment clearance a specific integration requirement. Its connection configuration comprises an XT90 main power connector and a JST-XH balance/telemetry connector, with cell matching tolerances of ΔIR ≤0.8mΩ and ΔCap ≤100mAh.
Full charging requires LiHV mode at 34.8V; standard LiPo mode provides approximately 20,500mAh usable capacity. Maximum charging current is 110A, with 5C recommended. Discharge ratings are 330A continuous and 550A for ≤10 seconds. For DJI Matrice 350 RTK or similar platforms, this non-smart, open-platform battery requires external power; custom adapter boards are available on request. Cycle life is ≥400 cycles at 300A and 80% depth of discharge. Heavy-duty operation involving changing payloads, temperature fluctuations and occasional deep discharge typically yields 280–350 flights before capacity falls below 80%.
