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.

7200 watts
Most golf carts peak way below this ... I would also check to see if you could convert to 48v .... 48v is just better tbh if you have the space and tbh it's likely your controller can be set to run on 48v.. Either way, it should work fine.. just be sure to get the lithium charger imo.
This price point is genuinely getting pretty "cheap" for something so out of the box ... My 2023 model 3 uses a ~60kwh LFP battery pack and after 21k miles .. i started with 272 miles of "max range" and now i'm sitting at 266 ... From what i've seen on the rest of the fleet, the lfp seems to be holding capcity way better than "normal" li-ion packs.
4 of these would be 14.3kwh for ~926 dollars. $3702 for 57kWh
I guess people weren't lyiing when they said the cost of LFP packs would come down.. This is genuinely pretty amzing that you can buy off the shelf LFP and be under 4k for a 60kwh pack.. and they still should be coming down in coming years.
Kinda blows my mind that you could potentially build a battery pack for an EV that will go ~300 miles on a charge for less than $4k with off the shelf parts, not even bargain hunting really except "look at slickdeals."
I wonder what the cost of these will be in another 3-5 years..
I'm not going to talk about the car as a whole, but my experience with lfp batteries over time so far has been nothing short of impressed.
