Extreme Temperature Lithium Battery (14.4V NCM, -40°C to 85°C Discharge) - OEM Wide-Temperature Battery Packs up to 48V
This extreme temperature lithium battery is an OEM-oriented wide temperature battery pack designed for field equipment that must deliver reliable discharge power across harsh climates, including lithium battery -40°C to 85°C operating conditions. The baseline architecture is 14.4V nominal (with support up to 48V max), built on NCM chemistry and intended for B2B integration into industrial automation, remote monitoring, outdoor communications, security systems, specialized mobility platforms, and aerospace/defense mission hardware.
Key advantages (bullets)
- Wide operating temperature battery behavior: engineered for discharge from -40°C to 85°C with temperature-aware protection and defined derating logic.
- 14.4V nominal platform, scalable to 48V max: supports both legacy 12V-class electronics and higher-voltage designs where lower current reduces harness losses.
- OEM / customer-designed interfaces: enclosure, connector, and BMS can be built to match device constraints, service access, and environmental sealing targets.
- Field-friendly diagnostics: customer-designed communication protocol supports fleet monitoring, maintenance logs, and clear fault taxonomy for distributed deployments.
- Ruggedization-ready design approach: suitable for vibration exposure, mobile installation, and outdoor handling when integrated with the correct mechanical restraints.
- Capacity scalability: standard 2Ah and 2.9Ah options, with support up to 29Ah for extended runtime applications.

Capacity overview
▼ 2Ah (standard)
Best suited for compact devices and sensor-centric systems where space is fixed and the load is moderate but temperature exposure is severe.
Typical use cases:
- wide temp battery for industrial sensors and remote monitoring terminals with intermittent radio transmissions
- portable test instruments used in outdoor or unconditioned environments
- telematics/tracking modules where size and weight drive mechanical design
▼ 2.9Ah (standard)
A higher energy option for longer service intervals and more frequent high-current events, while still keeping a relatively compact cylindrical-cell footprint.
Typical use cases:
- extreme temperature battery for outdoor communications backup loads with periodic modem bursts
- ruggedized surveillance systems requiring longer runtime during outages
- field instruments running continuous sampling plus scheduled data uploads
▼ Support max. 29Ah (high capacity)
For extended missions, long backup requirements, or mobile platforms that must sustain repeated pulse loads without frequent charging access.
Typical use cases:
- rugged battery for portable energy storage used in expeditions or emergency rescue support systems
- mobile robotics and delivery platforms requiring longer duty cycles
- marine and deep-cycle-oriented equipment where service intervals are longer
▼ Customer designed (OEM project)
Capacity up to 29Ah and voltage up to 48V max can be engineered to your system architecture, including builds commonly requested as a custom 14.4V 48V Li-ion battery pack for mixed product lines. Cell format (e.g., 18650 wide temperature battery pack) is selected based on current demand, packaging, and thermal constraints.
OEM & customization options
- Voltage & topology: 14.4V nominal baseline; support for higher-voltage packs up to 48V max to reduce current and improve cable/connector thermal margin.
- Cylindrical cell battery pack OEM builds: 18650/21700-based architectures, series/parallel selection, and interconnect design to meet pulse and thermal requirements.
- Battery case (OEM/customer designed): geometry, mounting points, sealing strategy, venting concept, label layout, and service access.
- Connector & harness (OEM/customer designed): locking connectors, keying, strain relief, pinout definition for power/data, and environmental protection.
- Custom BMS battery pack design: sensing topology, current limits, temperature derating curves, balancing strategy, sleep/wake behavior, and event logging.
- Communication protocol (customer designed): RS485/CAN/UART mappings as required, register definitions, fault codes, and firmware revision control for fleet consistency.
B2B services (OEM, wholesale, private label)
- OEM engineering support: requirements capture (load profile, standby vs. pulse behavior), voltage selection (14.4V vs. higher-voltage), and BMS rule definition.
- Design control for production: revision management, serialization/traceability, acceptance testing strategy, and documentation packs for importers and OEM QA teams.
- Wholesale supply programs: consistent builds for distributors serving utilities, telecom, security, industrial automation, and outdoor power channels.
- Private label execution: labeling, packaging, manuals, and SKU governance aligned to your warranty and service workflows.
FAQ section (minimum 6 questions, B2B focused)
1) What does "-40°C to 85°C discharge" imply for usable power?
It specifies the operating discharge window. Usable power at the extremes depends on the agreed derating curve, peak current requirement, and the system's minimum bus voltage. For OEM builds, we define these parameters against your device load profile.
2) Can you deliver an 18650 wide temperature battery pack for field sensors and telecom modules?
Yes. Cylindrical builds (including 18650) are supported when the current demand, thermal limits, and packaging constraints fit the format. Final selection is based on pulse current, runtime, and enclosure heat management.
3) Do you support a custom 14.4V 48V Li-ion battery pack across a product line?
Yes. We can engineer families of packs (14.4V baseline through higher-voltage variants up to 48V max) using consistent mechanical and communication concepts to simplify manufacturing and service.
4) How do you reduce nuisance shutdowns in outdoor communications backup power applications?
By coordinating BMS undervoltage thresholds, overcurrent response, and temperature derating with the modem/inverter inrush behavior and the minimum operating voltage of the electronics-especially critical in cold start scenarios.
5) Can the pack provide communication data for fleet maintenance systems?
Yes. The communication protocol is customer-designed and can include SOC/SOH, temperature channels, event logs, and clear warning/fault states to support maintenance decisions and warranty analysis.
6) What should OEMs provide to validate integration quickly?
Peak/continuous current, duty cycle, minimum device input voltage, charger specs, temperature exposure profile, mechanical envelope, connector/pinout, sealing targets, and expected annual volume. This enables correct series/parallel selection and BMS rule definition.
7) Is this appropriate for defense, UAV, or special mission equipment?
It is designed as an industrial wide temperature battery platform with OEM-defined ruggedization, traceability, and protocol needs. Final suitability depends on mission profile, mechanical constraints, and environmental requirements (altitude, vibration, sealing).
Short call to action (OEM / wholesale inquiry)
▲ Send your target voltage (14.4V nominal or up to 48V max), load profile (peak/continuous current and duty cycle), runtime target (Ah/Wh), operating temperature exposure, mechanical envelope, sealing requirements, connector/pinout, and desired communications. We will propose an extreme temperature battery configuration and an OEM integration plan suitable for industrial monitoring, outdoor communications, mobility platforms, and special-mission equipment.
