A UPS lithium upgrade is a compatibility project involving voltage window, charging, BMS, protection, communication, service and local requirements.
Customer situation
- The customer wants to review footprint, maintenance or lifecycle objectives.
- An existing lead-acid bank is due for replacement.
Load and runtime
- Confirm measured load and required backup duty.
- Do not assume equal nominal Ah produces equal project runtime.
- Use the actual load and UPS minimum DC voltage when reviewing current and energy duty.
UPS architecture
- Identify the exact UPS model, DC operating window and charging logic.
- Confirm required interlocks, dry contacts or communications.
- Confirm whether the existing system uses a center-tap or two-wire full bus.
Battery configuration
- Review battery nominal and operating voltage, usable capacity and current.
- Coordinate BMS, breaker, contactor, fusing, cable and cabinet.
- Record the existing lead-acid battery quantity, series/parallel arrangement and cabinet condition.
- Confirm normal and maximum charging voltage, charge-current limit, cut-off settings and restart behavior.
- Review existing lead-acid float/equalize control before approving lithium charging behavior.
Site limitations
- Installation environment and equipment clearances
- Local commissioning and emergency isolation
- Destination standards and transport documentation
Maintenance considerations
- Define local BMS and alarm support capability.
- Keep configuration, firmware and communication records.
- Plan safe replacement and end-of-life responsibilities.
Procurement questions
- What exact UPS and charger behavior must the battery support?
- What is the existing battery quantity and electrical arrangement?
- What are the UPS DC bus, minimum DC voltage and cut-off settings?
- Is communication mandatory or are dry contacts acceptable?
- Who will commission and service the system locally?
Delivery and documentation
- Confirm the selected model, accessories and packing list in writing.
- Confirm certification and shipping documents by model and destination.
- Define who handles installation, commissioning and local service.
Project risks
- Treating lithium as a physical drop-in replacement
- Selecting from UPS power or nominal voltage only
- Leaving communication and protection behavior undefined
