I have a power station but its internal battery is a 48 V, so when I run 12 V things you lose some efficiency stepping it down to 12 V. I also have a 12 V battery and I'll just often run those device devices directly from the battery and I get much more run time per ah of battery.
Community Reviews
This 12V 280Ah LiFePO4 battery is being used as a compact power storage pack for RVs, campers, boats, trailers, and off grid solar setups. It stands out for deep usable capacity, lighter weight than lead acid, Bluetooth monitoring, and enough output for things like trolling motors, fridge backup, and even running an air conditioner for hours in larger banks. The main cautions are that it is not a car starter battery, charging and inverter setups need the right lithium compatible gear, and some buyers flagged seller trust and coupon issues. A strong fit for 12V storage projects that need real runtime.
Common Questions (9)
The final price has varied a lot because different coupons and PayPal discounts have worked at different times. Buyers reported totals around $240-$280 after stacking discounts, while others saw the code fail or the price rise to about $305-$330 when promos expired.
Yes. It is being used in RVs, campers, boats, trailers, and even for trolling motors, with reports of good real-world performance. It is a large battery, so fit and weight matter, and some users suggest a 100Ah unit may be enough for lighter canoe or occasional use.
Several buyers reported receiving their batteries quickly and intact, and some noted strong store ratings and positive order experiences. Others warned to be cautious because the store identity and refund process on AliExpress can be confusing, so buyer protection is important.
No. It is a deep-cycle power-storage battery, not a starter battery, and the 200A BMS is not meant for the several-hundred-amp cranking loads most vehicles need. It can run accessories, RV loads, audio systems, and other 12V equipment, but not engine starting.
It may, because 12.8V × 280Ah equals 3.584kWh, which is above the 3kWh threshold mentioned for the credit. The battery would need to be installed and used for home power storage by the deadline, and the credit details depend on your situation.
Use a proper solar charge controller for panels, and for power-station charging the input is often limited by the connector and voltage. A standard XT60 setup can be limited to about 8A/100W, while XT60i and higher-voltage series setups can allow much faster charging.
Runtime depends heavily on the AC's wattage and whether it is running full blast or just maintaining temperature. A standard 13,500 BTU unit running constantly may last under 3 hours, while a lighter 5A 120V load is roughly about 5 hours after inverter losses.
No. It usually needs lithium-compatible charging settings and may require a different charger, solar controller, or DC-to-DC charger, especially in RV or alternator-charged setups. It can work well, but it is not a simple swap from flooded lead-acid.
Yes, it includes Bluetooth, and the listed low-temperature protection stops charging below -7°C and resumes at 0°C. That makes it more suitable for cold-weather use than batteries without charge cutoff, though charging in extreme cold is still a concern for LiFePO4.

You must have a small AC unit..most AC units use closer to 1350 watts. That battery will last less than 3 hours with a standard 13500 btu unit running constantly.

Could I run a whole camper trailer (30 amp) for 280a/30a hours?
