Heated 48V 100Ah Lithium Battery UL1973

Heated 48V 100Ah UL1973 Rack-Mount Lithium Battery — CLI100-48LT

The Canbat CLI100-48LT is a certified heated 48V 100Ah lithium battery ETL Listed to ANSI/CAN/UL 1973:2022 and tested to ANSI/CAN/UL 9540A:2025 — the combination of certifications required for regulated commercial, telecom, and industrial stationary energy storage installations in North America. Delivering 4.92kWh of usable energy in a 3U rack-mount form factor with CAN/RS485 communication, integrated self-heating for cold-climate operation to -25°C, and scalability to 32 units in parallel, the CLI100-48LT is engineered for infrastructure deployments where safety compliance, system reliability, and long-term operational uptime are non-negotiable requirements.

For telecom integrators, commercial solar installers, industrial UPS contractors, and engineers specifying energy storage for regulated indoor and cold-climate applications, the CLI100-48LT delivers a certifiable, deployable platform compatible with all major 48V inverter ecosystems — including SMA, Victron, Sol-Ark, Schneider, Goodwe, Sunsynk, Growatt, Deye, Sofar, Solis, SAJ, LUXPOWER, and more — with integrator-friendly terminal connections and flexible rack, wall, floor, or stack mounting configurations.

Ships free across Canada and the USA, backed by a 10-year warranty with Canadian-based technical and warranty support. For Canada and USA orders, there are no import duties or cross-border complications.

ETL Listed — UL1973 & UL9540A Certified

The CLI100-48LT carries the system-level certifications that regulated commercial energy storage installations require. In North America, commercial and industrial ESS projects typically require AHJ approval, building permits, insurance compliance, and utility interconnection agreements — all of which depend on certified equipment. Component-level UL cell certifications do not satisfy these requirements. The CLI100-48LT is certified at the system level.

The UL1973 and UL9540A combination provides the compliance foundation that engineers, inspectors, and commercial integrators need to specify, permit, and deploy with confidence:

UL9540A test results for the CLI100-48LT:

• Thermal runaway propagation performance criteria met
• No external flaming observed during testing
• No damage to adjacent units during evaluation
• No explosive gas discharge observed

Integrated Heating for Cold-Climate Infrastructure Uptime

For telecom towers, remote monitoring stations, pipeline infrastructure, utility installations, and any energy storage system deployed in Canadian climates, charging capability in sub-zero conditions is an operational requirement — not a convenience feature. A backup system that cannot accept charge during a winter power event is not a functional backup system.

The CLI100-48LT’s integrated heating system maintains charging capability down to -25°C. The system activates automatically when internal battery temperature falls between -25°C and -5°C and a minimum charging current of 8A (0.08C) is applied — warming the cells to 12°C before charge current is delivered to protect cell integrity and maintain certified operating parameters. Discharge operation is maintained down to -20°C.

When multiple CLI100-48LT units are connected in parallel, the heating system operates across the entire bank simultaneously — if any battery enters heating mode, all batteries in the parallel configuration begin heating, and heating stops once all batteries reach 12°C internal temperature.

Inverter Compatibility & System Integration

The CLI100-48LT communicates via CAN and RS485 protocols, enabling full BMS integration with all major 48V inverter/charger platforms. Integrators can deploy with confidence across the most widely specified commercial inverter ecosystems in North America:

Modular Architecture — Up to 32 Units in Parallel

The CLI100-48LT is designed for modular deployment. A single unit delivers 4.92kWh of usable energy at 48V nominal. Up to 32 units can be connected in parallel, building a certified 48V energy storage system of up to 157.44kWh of usable capacity — all within the same UL1973 and UL9540A compliance framework, with CAN/RS485 communication and coordinated heating maintained across the entire bank.

This modular architecture allows integrators to right-size the installation for current requirements and expand capacity incrementally as demand grows — without replacing existing equipment or redesigning the system architecture.

Applications

Telecom Backup Power

Telecom operators require backup power systems that maintain uptime through grid outages in all weather conditions. The CLI100-48LT’s UL1973 certification satisfies the safety compliance requirements of most telecom network operators, while its integrated heating ensures charging capability is maintained through Canadian winters at remote tower sites where temperature-controlled enclosures are impractical or unavailable.

Commercial & Industrial UPS Systems

For data centres, industrial facilities, commercial buildings, and critical infrastructure where UPS systems protect against power interruptions, the CLI100-48LT provides a certified LiFePO4 alternative to conventional VRLA battery cabinets — with significantly longer cycle life, higher energy density, lower maintenance requirements, and UL9540A thermal containment validation for indoor installation compliance.

Commercial Solar Energy Storage Systems

For commercial and light industrial solar-plus-storage installations where AHJ permitting and utility interconnection require certified equipment, the CLI100-48LT provides the compliance documentation that project approvals depend on. Compatible with all major commercial inverter platforms via CAN/RS485, deployable in rack or wall-mount configurations, and scalable to project-specific capacity requirements.

Remote Infrastructure & Cold-Climate Installations

Pipeline monitoring stations, weather installations, remote sensing arrays, oil and gas infrastructure, and utility assets deployed across Canadian and northern territories require energy storage that operates reliably through extended periods of sub-zero temperatures. The CLI100-48LT’s -25°C charging capability — the broadest cold-weather operating range in the Canbat lineup — combined with its modular scalability makes it the correct specification for these applications.

Regulated Indoor Commercial Installations

For installations in commercial buildings, server rooms, mechanical rooms, and any indoor space subject to fire code and building permit requirements, UL9540A thermal propagation testing is increasingly required by AHJs across North America. The CLI100-48LT’s tested and documented UL9540A performance — no external flaming, no propagation to adjacent units, no explosive gas discharge — provides the documentation that indoor installation approval requires.

UL1973 Heated 48V Lithium Battery for Telecom, ESS & Industrial UPS

The CLI100-48LT is Canbat’s certified commercial energy storage platform — a UL1973 ETL Listed, UL9540A tested 48V 100Ah LiFePO4 rack-mount battery engineered for telecom backup, commercial ESS, and industrial UPS applications requiring documented safety compliance, cold-climate operational capability, and scalable 48V architecture. It directly addresses the compliance gap that most lithium battery products leave open: the difference between component-level cell certifications and system-level deployment certification.

For integrators and engineers sourcing a UL1973 48V lithium battery in Canada, the CLI100-48LT ships free with no import duties, is supported by a Canadian technical team with commercial project experience, and carries a 10-year warranty.
