Hithium 280Ah LiFePO4 Cells Datasheet
Important Installation Notice:
To avoid contact resistance, the following points must be observed:
✔️ Thoroughly clean the battery terminals with ethanol or pure alcohol to remove oxide layers.
✔️ The terminals must not be touched with greasy fingers – they must be absolutely grease-free and clean.
✔️ Ideally, the contacts should be cleaned with a brass brush or fine sandpaper (grit 1000).
✔️ The contact surfaces of the cell connectors must also be carefully cleaned.
❌ The use of assembly greases, copper paste, or similar substances must be strictly avoided – they cause contact resistance, which can lead to heat generation and measurement errors during operation. As a result, the full capacity of the cells cannot be utilized.
🔧 Tighten the M6 screws with a torque of 6 Nm.
NOTE
- One Cell will come with 1 busbar, 2 flange nuts for free. (e.g. 4 pcs Cells will come with 4 pcs busbars, 8 pcs flange nuts )
- Each cell shall be used under the strict monitor, control, and protection by the BMS.
- Before the first use, always charge the cells to full voltage.
- We will match (capacity, voltage, resistance) all cells before delivery.
- The battery is suitable for DIY lovers with experience.
- The HITHIUM 280Ah LiFePo4 Cell has the same performance as CATL 3.2V 280Ah cells.
Warranty
The warranty period is 5 years from the date you receive.
We only replace new cell for free due to the failure of manufacturing.
Before the shipment, we will detect the cell voltage/resistance/appearance and other issues. we can only ensure that single cell is good before the shipment.
When arrival you can test the cells within 1 week, if you found problems please contact us for refund or replace. Any return behavior buyers need to be responsible for shipping fee.
Remark
Please read carefully all the description before taking orders, the battery is suitable for DIY lovers with experience, people who are not familiar with the safe use of lithium battery knowledge, please go to our shop to buy the finished product.
DIY battery pack must get the cells balanced (same voltage ) before assembly.
And we don’t accept refund for buyers who don’t know how to assembled or unbalanced assembly.
Please use the correct BMS during assembly. We don’t accept refund for the problem caused during assembly process or after the assembly. Such as not use the BMS, the BMS connected to the wrong wire lead to battery damage, charger failure, the assembly error or unbalanced assembly, etc.
Before assembling, please make sure use the same capacity cell and use the same brand of the cell. It is forbidden to mix cells with different capacity and brand in the same battery system. Otherwise, we will not be responsible for quality assurance.
Application
Solar energy storage, solar power system, UPS supply, Engine starting battery, Electric bicycle/motorcycle/scooter, Golf trolley/carts, RV, EV, Caravan So on.

Q1: What are the environmental features of this battery?
The battery is made from lithium iron phosphate (LiFePO4), an environmentally friendly material that does not contain heavy metals or rare metals. It is safe and stable, not prone to burning or exploding under high temperatures, impacts, or short circuit conditions.
Q2: How should this battery be maintained to prolong its lifespan?
Regularly check the battery's exterior and connections to keep them clean and dry. Avoid keeping the battery in a state of overcharge or deep discharge for extended periods. Be mindful of the ambient temperature during use; avoid charging in extremely cold conditions.
Q3: What are the installation requirements for this battery?
The battery can be installed in any position as it does not contain acid. Ensure that the battery is securely mounted to prevent vibrations and impacts during movement.
Q4: How long do BetterESS batteries last?
Our LiFePO4 lithium iron batteries can provide 2000+ cycles, which is significantly more compared to the 300–500 cycles typically found in lead-acid batteries. The service life of LiFePO4 batteries is 8 to 10 times longer than standard lead-acid batteries.
Q5: Are your batteries safe?
Yes, our LiFePO4 batteries are designed with safety in mind. They are manufactured using Automotive Grade LiFePO4 Cells, offering higher energy density, no memory effect, and more stable performance. The stable chemical structure of LiFePO4 ensures they do not burn or explode, even under high temperatures, short circuits, impact, or drops.
Q6: Are there any special handling or maintenance tips for this battery?
The LiFePO4 battery requires minimal maintenance. However, it is recommended to regularly check connections and ensure the battery is kept in a dry and ventilated space. Avoid exposure to extreme temperatures to prolong battery life.

Battery capacity is very large, can reach more than 295ah, after 15 days of transport received the battery is very good, no damage, I am very satisfied
D
The package arrived after about 5 days. All cells look good and got correct parameters. Happy to have it, will order more after some long term testing
S
Batterie arrivate e tutte alla stessa tensione ottima comunicazione con il venditore per adesso perfetto!!!
S
The batteries arrived quickly, well packaged, and all 16 cells were at the same voltage — 3.29V. All of them are in perfect shape. Now I'm doing the top balancing, and then I will assemble the two batteries.
