Is a 12V LiFePO4 battery the same as 12.8V?

Yes. A 12V LiFePO4 battery is 4S — four 3.2V cells in series — giving 12.8V nominal. “12V” is the lead-acid replacement shorthand and “12.8V” is the true nominal voltage; both labels describe the same pack.

How do I choose capacity for an off-grid installation?

Size on usable energy rather than label Ah, then divide by the daily load to get autonomy in days. Where runtime matters more than weight, paralleling two identical packs is preferred — check they are the same model and age first.

Can I charge a 12V LiFePO4 battery with a lead-acid charger?

Only if the charger has a LiFePO4 profile or an adjustable absorption voltage in the 14.4V to 14.6V class. A lead-acid float profile will undercharge the pack, and a desulfation or equalisation cycle will damage the BMS and the cells.

Do you supply 12V LiFePO4 batteries for OEM projects?

Yes. OSM Battery supplies the 12V LiFePO4 range on OEM and ODM terms, covering customer branding, terminal specification, custom case tooling and BMS parameter configuration, with low-volume samples available for design validation.
