12.8-280
UGA POWER
850760000
The 12.8-280 is a 12.8V 280Ah LiFePO4 battery listed for solar storage, home backup and UPS use. It combines 3584Wh of nominal energy with prismatic cells, M8 terminals and an ABS enclosure measuring 522 × 240 × 218mm.
The 280Ah model carries a listed energy figure of 3584Wh. This provides a starting point for storage assessment, rather than a guaranteed AC runtime. Buyers need to define the load profile, inverter requirements and intended reserve before finalising system capacity.

Selection note: The 250A BMS appears in the product title only; continuous/peak pack-current limits require confirmation. The second source row labelled “Nominal Voltage” contains Ah values and is presented as capacity below.
The published range includes 68Ah, 120Ah, 160Ah, 175Ah, 280Ah and 350Ah model names. Their enclosures differ. The 280Ah version is 522 × 240 × 218mm; moving to a different capacity therefore requires another dimensional check.
Prismatic cells sit inside an ABS shell with an IP65 enclosure rating. M8 terminals define the connection interface. Customer-specified cell models are listed as an available request; any chosen cell and its final pack specification should be agreed for the order.
The charging voltage is 14.6 ±0.2V, with a specified charging temperature range of 0°C to 45°C. Check the charger or solar charge controller settings against these requirements. The maximum charging current for the 280Ah configuration should also be confirmed before commissioning.
The specified discharge temperature range is −20°C to 60°C. The battery is rated for more than 3,000 cycles at 0.2C and 100% depth of discharge, with the test endpoint defined as 80% remaining capacity. Actual cycle life depends on operating temperature, charging and discharging practices, and other application conditions.
For storage periods exceeding three months, keep the battery in a cool, dry environment at a storage voltage of 12.8–13.2V. The specified long-term storage conditions are 23 ±2°C and 45%–75% relative humidity, with recharging every three months. The general storage temperature range is 0°C to 45°C.
Potential applications include solar and wind energy systems, UPS backup, golf carts, low-speed electric vehicles, solar lighting, and home backup power. The 12.8V lithium battery range provides additional capacity options for comparison. Final selection should account for the equipment's voltage, current demand, operating profile, and installation requirements.
FOBERRIA offers lithium and lead-acid battery solutions. To evaluate the 12.8V 280Ah battery for a specific installation, provide the inverter's rated power and surge demand, battery-bank configuration, charging parameters, and available installation space through the FOBERRIA project enquiry page. Confirm the supplied product's branding and specifications before placing an order, as the listed brand is UGA POWER.
The 12V280Ah column lists 3584Wh at 12.8V and 280Ah. Delivered system energy depends on the selected operating limits and connected equipment; the figure is not a fixed home-backup runtime.
The title mentions a 250A BMS, but the 12V280Ah table does not define a continuous discharge rating. Obtain a model-specific current specification before choosing the load or inverter.
The shared series specification is 14.6 ±0.2V. The 12V280Ah pack’s charger should also respect the listed 0°C to 45°C charging range and a separately confirmed current limit.
The 12V280Ah enclosure is 522 × 240 × 218mm and uses M8 terminals. Check both the case dimensions and access for the chosen cable connections.
For storage beyond three months, the guidance specifies 12.8–13.2V and recharging every three months. The stated long-term environment is 23 ±2°C with 45%–75% humidity in a dry, cool place.
No. The 12V350Ah column lists 520 × 269 × 220mm, while 12V280Ah is 522 × 240 × 218mm. Capacity substitution requires a fresh enclosure-fit check.
