8S 40000mAh UAV Battery

HSS Energy's China 8S 40000mAh UAV Battery uses a 29.6V nominal 8S architecture with 40Ah capacity and 1184Wh nominal energy. The finished pack is approximately 3.44kg, giving a calculated complete-pack reference of about 344Wh/kg from the supported energy and mass values. This model is positioned above HSS 6S 40Ah platforms when the aircraft electrical architecture requires an 8S window rather than simply more capacity.

Product Specifications

The HSS 8S40Ah reference configuration should be approved as one electrical-mechanical system: voltage window, charge profile, current demand, battery-bay envelope, cable, connector, polarity, cooling and operating temperature should be confirmed before sample use.

Electrical, Energy and Mechanical Data

¹ Approx. 200-400 cycles is the current HSS Energy general planning reference when no separate approved pack-level cycle report is applied. By the end of this range, available capacity typically declines to about 80% of initial rated capacity under specified conditions. Actual results vary with charge/discharge rate, depth of discharge, temperature, storage practice and end-of-life criteria.

8S Industrial Architecture and HSS Matrix Position

The 8S 40Ah UAV battery has a distinct engineering role within the HSS 40Ah family compared with the 6S high-energy and high-current configurations. Selection starts with the aircraft electrical architecture: 29.6V nominal, 34.0V charge cutoff and 20.0V discharge cutoff. At nominal voltage, 120A continuous is an arithmetic reference of about 3.55kW, while 400A maximum corresponds to about 11.84kW; neither value is a guaranteed aircraft-output claim, and the applicable maximum-current duration follows the approved configuration.

120A is the continuous rating; the 400A maximum-discharge duration depends on the approved configuration.

HSS matrix selection: 8S industrial architecture is a different procurement problem from 6S energy-to-weight or 6S sustained-current platforms.

Maximum charge current is 20A at 0.5C with a 34.0V charge cutoff. Confirm average current, maximum-current duration, cable and connector temperature, charger control, cooling, reserve policy and aircraft voltage acceptance before sample approval.

Mechanical Fit and Interface Control

HSS 8S40Ah reference envelope and optional interfaces. For a long endurance drone battery evaluation, final dimensions, pack mass, cable length, polarity, connector exit direction and tolerances should be controlled by the approved order drawing.

Semi-Solid-State External-Force Safety Design

For a semi solid state drone battery, mechanical-abuse behavior is an important customers question because a large-energy pack can experience puncture, crush, impact or structural damage during handling or aircraft incidents. Compared with conventional liquid-electrolyte cell designs, semi-solid-state electrolyte architectures can provide a higher safety margin after external-force damage by reducing reliance on free-flowing liquid electrolyte, lowering leakage tendency and improving mechanical-abuse tolerance in appropriately designed cells. This is a technology-level advantage, not a universal guarantee: actual response depends on cell design, state of charge, temperature, damage mode and test method.

The damaged pouch-cell sample illustrates external-force / puncture evaluation; exact test method, state of charge, temperature, acceptance criteria and applicability to the finished 8S pack are confirmed against the relevant test record.

Industrial UAV Application and Manufacturing Support

Primary applications include custom mapping, surveying and infrastructure-inspection aircraft that accept the defined 8S voltage window. As a 29.6V 40000mAh UAV battery, the 1184Wh energy class and 120A continuous rating support engineering review for sustained professional missions. For customers comparing an 8S drone battery, this platform is differentiated by its 29.6V architecture and 1184Wh installed energy rather than by a 6S long-range or 6S high-current configuration. Secondary applications can include corridor inspection and medium-lift route evaluation, but final compatibility requires aircraft-level validation.
