NEW JOURNEY
Product Description
This 8S assembly uses the 9987191-40000mAh cell designation. The 8S 40000mAh Solid State UAV Battery combines a 29.6V nominal platform with a 34.0V charge cutoff and 20A maximum charge current. Its finished dimensions are 93 x 90 x 205mm, subject to tolerance. When comparing another 40Ah pack, retain this model’s mass, cell identity and current rating together.
Cell Energy Density
The stated 400Wh/kg rating applies to the individual 9987191-40000mAh cell reference. Use the corresponding cell specification or test record to confirm its measurement conditions. Pack leads, insulation and wrapping belong to the assembly design; their mass or external outline must not be used to reverse-calculate or question the cell rating. For aircraft integration, review pack weight, dimensions and discharge limits separately.

Product Details
Energy and Aircraft Load
For this 8S 40000mAh drone battery, 1184Wh is nominal stored energy, not a flight-time result. The approximately 3.2kg mass must be included in the aircraft energy budget. Hover or cruise power, payload and landing reserve determine how much of that energy is useful on a particular mission.
Check the pack against the cell reference
A procurement review should keep the cell identification, complete-pack mass and finished dimensions in separate fields. Capacity and voltage results should state the actual test conditions. This prevents a cell-level figure from being copied onto a finished-pack acceptance record without its basis.

FAQ
What should I compare before selecting 8S 40000mAh Solid State UAV Battery?
nominal voltage: 29.6V for this model, compared with 22.2V for 6S 40000mAh Semi-Solid UAV Battery; nominal energy: 1184Wh, calculated from 29.6V x 40Ah for this model, compared with 888Wh (calculated from nominal voltage and rated capacity) for 6S 40000mAh Semi-Solid UAV Battery.
Does every 8S 40Ah pack have the same discharge rating?
The 9987191 reference on this page lists 80A continuous discharge and approximately 3200g. The separate CGB10087191NSH listing records 120A and approximately 3440g. Use the cell designation as well as capacity when identifying the ordered pack.
How much installation space should I allow for this battery?
Finished pack dimensions: 93 x 90 x 205mm, each dimension +/-5mm; Approximate finished pack weight: 3200g. The battery bay also needs space for the cable exits, connectors and restraint. Support the battery body independently of its wires; the body envelope does not include every installation clearance.
Which connection details should be fixed for this battery?
Power lead: 8AWG, 150mm; Power plug: XT90. Main power and balance connections serve different purposes. Keep the pinout and polarity tied to the ordered harness, and approve the connector and wire limits for the actual load; a matching plug shape is not a current rating.
