12V-class lithium batteries for OEM and B2B supply.
12.8V LiFePO4 reference packs across compact, deep-cycle, backup and high-capacity formats—with model-specific BMS and charger review.

“12V lithium battery” is a market family, not one electrical profile.
A four-series LiFePO4 pack is commonly sold as 12V-class while its nominal voltage is 12.8V. Charge voltage, protection limits and behavior differ from a 12V lead-acid battery, so replacement projects must review the charger, equipment cutoff and current demand.
Capacity labels such as 100Ah or 150Ah do not prove load capability, case fit or parallel suitability. The exact BMS, current path, terminals, enclosure and documents are tied to the selected model.
Start from a real configuration, then confirm the project version.
Reference models demonstrate available form factors and engineering experience. Current drawings, component revisions, documentation, MOQ and delivery terms are reconfirmed before quotation.

| Commercial | No universal price, MOQ, lead time or warranty; confirm against model, customization and destination. |
Questions purchasing teams ask.
Is 12.8V the same as 12V?
12.8V is a common nominal rating for a four-series LiFePO4 pack sold in the 12V market. Compatibility still depends on the complete operating and charging window.
Can I replace a 12V lead-acid battery directly?
Sometimes, but only after checking charger profile, equipment cutoff, surge current, BMS behavior, mechanical fit and system approval.
Can 12V batteries be connected in series or parallel?
Only models explicitly approved for the proposed configuration should be used. Matching, protection, current sharing and installation rules must be defined.
Need a 12V-class battery for a product or project?
Send the application, charger, load, dimensions, quantity and destination.
