Wide Temperature Range Lithium Battery Custom Extreme Temperature Battery Pack Custom Wide Temperature Battery

• Operating window engineered for harsh environments: lithium battery -40°C to 85°C discharge capability for extreme cold starts and hot enclosure operation
• OEM-configurable platform: battery case, connectors, BMS, and communication protocol can be customer designed to match your system architecture
• System voltage scalability: Wide Temperature 10.8V Lithium Ion Battery base design, with pack configurations supporting up to 48V for higher-power loads
• Capacity scalability: standard 2Ah and 2.9Ah, with design support up to 29Ah high capacity lithium battery configurations
• Integration-ready controls: protection, telemetry, and logic suitable for remote monitoring and fleet-managed assets (e.g., custom BMS with CAN communication by request)
• Ruggedization options: mechanical reinforcement for vibration/shock, sealing concepts (including IP67 waterproof lithium ion battery design paths), and serviceable harnessing
• Application-aligned performance: optimized for intermittent high loads (radios, actuators, drones) and long-duration standby/low-power duty cycles (sensors, SCADA endpoints)

A conventional lithium-ion pack often fails at the system level in cold climates not because the cell "has no energy," but because internal resistance rises sharply at low temperature, causing voltage sag under load and triggering protection thresholds. At the opposite extreme, elevated temperature accelerates electrolyte degradation and SEI growth, reducing cycle life and increasing impedance.

This extreme temperature lithium battery platform is engineered around three principles:

• Cold-load stability: cell selection and BMS thresholds are tuned to reduce nuisance cutoffs during cold starts and pulse loads common in field electronics, robotics, and emergency equipment.
• Thermal resilience: pack design emphasizes predictable heat flow, conservative limits, and protection logic that accounts for hot soak conditions in sealed housings, engine bays, UAV enclosures, and maritime cabinets.
• System-level design, not just cells: the wide temperature battery pack is treated as a subsystem-electrical, firmware, mechanical, and connector interfaces are aligned to your duty cycle, peak current, and environmental profile.

Result: an ultra wide temperature battery designed to maintain usable power delivery where standard packs frequently exhibit brownouts, shortened service intervals, or unexpected protective shutdowns.

Standard options: 2Ah and 2.9Ah (support up to 29Ah)

▼ 2Ah (nominal)
Best fit when size/weight is constrained and load profiles are moderate:

• Industrial IoT Battery for Extreme Temperatures: pipeline corrosion monitors, smart grid sensors, SCADA field devices with periodic transmit bursts
• Field communication gear: tactical radios or encrypted comms where portability is critical
• Portable test equipment: handheld terminals, inspection instruments, metering devices

▼ 2.9Ah (nominal)
Preferred for longer runtime or higher average loads in the same voltage class:

• Rugged mobile hardware for warehouse/logistics with extended shifts
• Robotics auxiliary power: AGV/AMR power packs, robotic arm auxiliary units for control electronics and sensors
• Backup power for emergency equipment: thermal imaging cameras, gas detectors, portable lighting systems

▼ Up to 29Ah (customer designed)
For applications where extended endurance, higher duty cycle, or multi-day autonomy is required:

• Commercial vehicles: sleeper-cabin APU functions, refrigeration unit backup power in cold chain trucks
• Unmanned systems: longer-duration UAV missions, mapping/inspection payloads, and maritime instrumentation
• Remote infrastructure: utility monitoring nodes with long service intervals and harsh climates

All capacities can be configured as a wide temp lithium ion battery module with application-specific current limits, protection thresholds, and harnessing.

This is an OEM platform, not a fixed retail SKU. We support customization aligned to your electrical and mechanical integration plan:

• Voltage configuration: 10.8V nominal architecture, scalable to custom 48V lithium battery pack configurations
• Capacity design: 2Ah / 2.9Ah standard, scalable to 29Ah with parallelization and thermal design review
• Enclosure: OEM or customer-designed housing; mounting features, heat spreading, service access, labeling, and serial/traceability formats
• Connector & harness: OEM/customer-specified connectors, cable gauges, strain relief, keyed interfaces, and assembly routing
• BMS & firmware: protections, current limits, sleep/wake logic, transport mode, fuel gauge behavior, event logging
• Communication protocol: customer designed (e.g., CAN/UART/RS485 and message mapping as required)
• Environmental sealing: design options for dust/water exposure, including IP-rated concepts such as an IP67 waterproof lithium ion battery enclosure strategy where required

▼ Cell system (NCM)
NCM chemistry enables a compact form factor and strong energy density for mobile and airborne systems. Cell selection can include cylindrical wide temp battery cell approaches depending on mechanical constraints and current requirements. The goal is stable impedance behavior across temperature and predictable voltage under load.

▼ High discharge & pulse loads
For UAV takeoff bursts, motor controllers, actuators, lighting inrush, and radio transmit peaks, the pack is designed with:

• current paths sized for peak demand (busbar/wire gauge and connector selection)
• BMS limits set to protect cells without triggering avoidable brownouts
• optional power-stage and NTC placement strategy to reflect true thermal hotspots

▼ Vibration & shock
Industrial robotics, heavy equipment, and vehicle installations require mechanical robustness:

• cell retention and cushioning concepts to minimize fretting and weld stress
• reinforced harness anchoring and strain relief
• mounting interface designed to avoid resonant failure modes

▼ Thermal management logic
An extreme temperature battery pack is only as reliable as its protection and sensing:

• temperature sensor placement aligned with your heat sources and pack geometry
• configurable cutoffs, recovery thresholds, and derating behavior
• options for cold-start logic and low-temperature charge constraints (application-dependent)

▼ Communication protocol
For fleet assets and remote monitoring, we support customer-designed telemetry and controls:

• SOC/SOH reporting (as applicable)
• fault and event codes aligned to your service workflow
• optional interfaces for custom BMS with CAN communication and message mapping to your gateway/ECU

Successful deployment in harsh environments depends on integration details. We collaborate with OEM engineering teams on:

• Mounting & serviceability: bracket patterns, vibration isolators, access for replacement, and safe handling features
• Ingress protection: gasket design, venting concept (if required), connector sealing, and cable entry strategies
• EMI/EMC readiness: grounding approach, cable shielding, and layout practices for noisy robotics/vehicle environments
• Thermal interfaces: heat spreading to chassis, insulation from hot components, and internal hotspot mitigation
• Safety & transport: labeling, shipping mode, and storage behavior consistent with your logistics model
• System power architecture: startup inrush, brownout thresholds, DC/DC selection, and wiring losses over harness length

* Final charge voltage and charging strategy depend on cell selection and BMS configuration.

• OEM design-in support: requirements review, interface definition, and integration guidance for industrial and mobility platforms
• Wholesale supply: repeatable builds for importers, distributors, and project-based procurement
• Private label & branding: labeling, packaging, documentation set alignment, and traceability formats
• Documentation package (project-dependent): electrical specification, harness drawings, integration notes, and test reports agreed during development
• Change control: controlled BOM/firmware revisions to support long-life programs common in utilities, defense, and industrial markets

Share your voltage (10.8V to 48V), capacity target (2Ah to 29Ah), peak/continuous current, and temperature profile. We will propose a wide temp lithium ion battery configuration-including enclosure, BMS, connectorization, and communication-optimized for your equipment and supply model (OEM, importer, distributor, or wholesale).
