Sep 03, 2026Industrial UAVs and heavy-lift drones push battery systems harder than almost any other application. High-load missions demand high continuous current, sudden power peaks and absolute reliability — because a power cut in the air is not an inconvenience, it is a safety event. That is why the battery management system (BMS) matters as much as the cells themselves. As a professional lithium battery manufacturer, UFOPOWER designs and builds a 24S–32S 400A smart BMS purpose-made for industrial UAV battery packs, covering high-power, high-voltage platforms with flight-safe protection logic and full protocol integration.

A smart BMS for industrial UAV battery packs is responsible for far more than basic protection. It must deliver 400A of continuous discharge for high-load platforms, survive 600A peak demands during aggressive manoeuvres or heavy payloads, and coordinate large-capacity power systems built from multiple packs. It also has to talk to the aircraft: modern UAV control systems expect live battery telemetry — state of charge, cell voltages, temperatures and fault states — over standard protocols, so the BMS becomes part of the flight control ecosystem rather than a standalone safety box.
UFOPOWER's 24S–32S design addresses these demands across an 88.8V–118.4V operating range. It manages lithium packs from 24 to 32 series cells, supplies 400A continuous discharge with 600A peak capability, and coordinates up to eight battery packs in parallel — a configuration that suits large-capacity Li-ion power systems on industrial aircraft, heavy-lift logistics UAVs and eVTOL prototypes.

A ground vehicle that loses power simply stops. A UAV that loses power falls. This difference drives the protection philosophy of the UFOPOWER design: warning first, cutoff only when the aircraft is safe. The BMS supports flight-mode logic that prioritises warning output and avoids sudden power cutoff while the aircraft is in the air — for example, a pack undervoltage warning does not shut down the discharge MOSFET during flight.
| Protection function | How it works |
|---|---|
| Overcurrent and short-circuit control | Short-circuit trip at 1,500A with 200µs response time; recovery after load removal |
| Charge / discharge voltage protection | Warning and cutoff voltages computed from the selected series count; overvoltage disables the charge MOSFET |
| High- and low-temperature safeguards | Four independent NTC inputs track pack temperature and respond before thermal risk builds up |
| Flight-mode protection | Prioritises warnings and avoids power loss in the air |
| Vibration-resistant mechanical layout | Layout engineered for vibration-heavy operating environments |

Integration flexibility decides how easily a BMS fits into a real UAV programme. This design provides dual isolated data paths — CAN 2.0B and isolated UART — with communication wake-up, plus compatibility with DroneCAN (UAVCAN), Modbus and smart-charger links. That means it works with popular open flight-control ecosystems such as PX4 and ArduPilot, and can hand live state-of-charge, fault and diagnostic data straight to the aircraft control system. An isolated RS485 channel supports Modbus with adjustable baud rate and configurable device IDs from 0 to 255, while optional Bluetooth lets engineers view live battery status and diagnostics from a mobile app. Type-C access, SOC display output and LED indicators can be matched to different UAV pack designs, and a configurable storage-discharge function with idle-time thresholds helps extend battery service life between missions.
Coordinating up to eight packs in parallel turns a single BMS into the brain of a large-capacity power system. This makes the design a strong fit for the most demanding industrial UAV roles:
Heavy-payload logistics UAVs — high-current control for aircraft carrying large loads through demanding missions.
Industrial cargo drone fleets — parallel-pack management for longer endurance and strong output.
Large UAV and eVTOL platforms — high-voltage pack supervision for prototypes and next-generation designs.
Emergency response drones — reliable monitoring under time-critical, high-load profiles.
Industrial inspection aircraft — dependable power delivery with live fault feedback.
Autonomous high-power aerial systems — scalable management and protocol integration.
Every UAV programme is different, and off-the-shelf protection thresholds rarely match a specific airframe's flight envelope. As a professional lithium battery manufacturer, UFOPOWER offers factory-direct OEM/ODM custom battery solutions: pack series count, interfaces, protection thresholds, SOC display logic and even charge-recovery conditions can be adjusted around each UAV programme. In-house production with strict quality control and 100% factory testing ensures every BMS ships ready for vibration-heavy, high-current service.
