Extreme Temperature Battery Pack (25.2V NCM) for Robotics, UAV, Defense & Industrial Tools - OEM Supply
This extreme temperature battery pack is a wide operating temperature battery engineered for OEM equipment that must start, discharge, and remain predictable from -40 °C to 85 °C. Built on NCM chemistry at 25.2V nominal (with support up to 48V max), it targets B2B programs in robotics and autonomous systems, outdoor and military electronics, and professional/medical tools where enclosure, connectors, and communications must be designed around the host device-not standardized consumer formats.
Key advantages (bullets)
- Discharge from -40 °C to 85 °C: suitable where conventional Li-ion packs derate sharply or fail to start in cold environments.
- 25.2V nominal platform (expandable to 48V max): supports stable high-voltage rails for motors, sensors, compute modules, and actuators.
- OEM-defined mechanical and electrical interfaces: battery case, connector, BMS, and protocol can be designed to match the end product and service workflow.
- BMS strategy aligned to extreme climates: configurable limits, temperature-aware current derating, and fault handling to protect cells and reduce nuisance shutdowns.
- Designed for mobile/field equipment: attention to vibration exposure, transient loads, and connector retention for platforms such as inspection robots, AGV/RGV, and portable detection instruments.
- Scalable capacity roadmap: standard 2Ah and 2.9Ah builds, with support up to 29Ah for higher-energy mission profiles.

Capacity overview
▼ 2Ah (standard)
A compact energy option for weight-sensitive or space-limited designs where the pack primarily supports sensing, comms, and intermittent actuation.
Typical use cases:
- portable detection/exploration instruments with short duty cycles
- small inspection robots with hot-swappable pack concepts
- optical/electronic payload power where mass is constrained
▼ 2.9Ah (standard)
A higher baseline for longer runtime without major mechanical growth, often selected for platforms with continuous compute plus periodic motor loads.
Typical use cases:
- battery for inspection robot platforms operating longer patrol routes
- AMR/AGV subsystems (controllers, sensors, comms) requiring longer hold-up time
- professional tools needing higher current stability under repeated bursts
▼ Support up to 29Ah (high capacity)
For extended missions, higher duty cycles, or power-hungry payloads. This tier is commonly used when the equipment cannot rely on frequent charging access.
Typical use cases:
- outdoor monitoring and security devices deployed for long shifts
- mobile robotics requiring longer autonomy windows
- medical equipment battery pack applications where runtime and voltage stability are prioritized
▼ Customer designed (OEM project)
Capacity, voltage (up to 48V max), and packaging can be engineered to the device power profile and service constraints, including custom form factors, mounting points, and harness design.
OEM & customization options
This platform is intended for OEM programs that require control over interfaces, behavior, and compliance documentation.
- Voltage & series configuration: 25.2V nominal baseline with support up to 48V max, aligned to motor drivers, compute rails, and DC/DC architecture.
- Battery case (OEM/customer designed): enclosure geometry, mounting bosses, sealing strategy, label layout, and service access planning.
- Connector & harness (OEM/customer designed): high-retention connectors, keying, strain relief, cable routing, and pinout mapping for power + data.
- BMS (OEM/customer designed): current capability, temperature sensing plan, protection thresholds, balancing strategy, sleep/wake logic, and event logging.
- Communication protocol (customer designed): RS485/CAN/UART mappings as required (including RS485 communication battery implementations), register definitions, and firmware version control.
- Safety & service features (as specified): fusing approach, pre-charge requirements for high-inrush loads, and field replaceability expectations.

FAQ section
1) Can you support a wide temperature lithium battery that discharges at -40 °C for mission start?
Yes. The pack is designed for -40 °C to 85 °C discharge behavior with temperature-aware control logic. Final usable power at temperature depends on the load profile and the agreed derating curve.
2) Is this a 25.2V 18650 Lithium Ion Battery Pack?
It can be engineered as a 25.2V (7S) Li-ion pack using cylindrical cells (including 18650/21700 formats) depending on capacity, current, and mechanical constraints. Cell format is selected during OEM design to match power density, thermal behavior, and packaging.
3) What is the typical charge voltage for a 25.2V nominal NCM pack?
A typical full-charge voltage for 7S NCM is 29.4V. Charging limits should be coordinated with cell spec, BMS thresholds, and the charger algorithm used in your device.
4) Can you provide a custom BMS battery pack with RS485 communication?
Yes. We support custom BMS battery pack designs with customer-defined RS485 communication battery mapping (or CAN/UART), including SOC reporting, alarms, logs, and version-controlled registers.
5) How do you manage vibration and connector reliability in mobile robots and off-road equipment?
Reliability is designed through enclosure reinforcement, cell retention methods, connector locking/strain relief, and harness routing rules. We align these choices to your vibration profile and service handling requirements.
6) What information do you need to quote an OEM project accurately?
Load profile (continuous/peak current, duty cycle), temperature exposure, charger details, mechanical envelope, connector/pinout requirements, communication needs, target compliance documentation, and expected annual volumes.
