12.8V battery packs: applications, capacity and selection
12.8 V LiFePO4 packs drop in for most 12 V lead-acid batteries, serving energy storage, UPS backup, solar street lighting, security and low-speed vehicle support. We design, build and deliver to your capacity, size and interface.
Applications
Where this voltage platform is used
12.8 V is the LiFePO4 voltage that maps directly onto 12 V lead-acid, so replacements fit without reworking cabinets or wiring. Storage, UPS and solar lighting put the emphasis on cycle life and safety, so we design the pack as a whole against your discharge profile, cycle frequency and communication needs.
UPS backup
Solar street lighting
Security systems
Low-speed vehicle support
RV and outdoor power
Portable energy storage

FAQ
Common questions about 12.8V battery packs
Can a 12.8 V pack directly replace a 12 V lead-acid battery?
Most 12 V lead-acid applications can be replaced directly. 12.8 V is the LiFePO4 platform that maps onto the 12 V lead-acid system, so replacement usually needs no rework of the cabinet or wiring. Provide the dimensions, terminals and charge-discharge duty of the original battery and we will confirm the match.
How are capacity and cycle life matched for storage and UPS?
Against your daily discharge and cycle frequency. Provide the load power, backup duration and cycling pattern, and we set the capacity direction and the matching proposal, confirmed per model.
What certification and documents are needed for export?
CE / IEC 62133 / UL 2054 / RoHS / REACH have been passed, and the applicable items are confirmed per your target market and model. Export transport documents are confirmed per model, with the specific items set by your order and target market.
