Safety Guidelines & Warnings
⚠️ IMPORTANT SAFETY NOTICE ⚠️
LiFePO4 batteries require proper handling and knowledge to ensure safe operation. Failure to follow safety guidelines may result in fire, explosion, serious injury, or property damage.
General Safety Guidelines
✔ Only purchase and use if you fully understand lithium iron phosphate (LiFePO4) battery safety.
✔ Always charge using a compatible LiFePO4 charger—never use non-compatible chargers.
✔ Store batteries in a dry, cool environment away from direct sunlight and heat.
✔ Use only within manufacturer-listed specifications and in protected battery packs.
✔ Ensure proper battery management system (BMS) usage for safety and longevity.
✔ If assembling a battery pack, ensure proper cell balancing before use.
✔ Resellers must provide these warnings to all customers.
🚫 Prohibited Uses & Handling
⛔ DO NOT short circuit, puncture, cut, crush, incinerate, or modify the battery.
⛔ DO NOT use if the battery casing is damaged, swollen, or leaking.
⛔ DO NOT overcharge or over-discharge—this can lead to cell damage and reduced lifespan.
⛔ DO NOT expose the battery to water, extreme heat, or direct sunlight.
⛔ DO NOT connect in series or parallel without ensuring proper voltage balancing.
⛔ DO NOT solder directly—only use spot welding for battery pack assembly.

Frequently Asked Questions
The outbound quality control report is done by all manufacturers and tests electrical performance metrics to ensure they meet all standards.
The cells are tested many times throughout the manufacturing process but EVE will only provide us with the final test report which is done just prior to them leaving the EVE facility.
Because the EVE LF280K we offer include the EVE Dual screw terminal block, which is manufactured and installed by EVE, our cells get sent to the EVE pack building production line for this process.
The outbound quality control test report we provide is completed by the pack building production line and may appear slightly different from the report done by the cell production line. (ie. Our EVE LF105 cells).
Other vendors will choose to have the terminal welds done themselves or by a third party. In this case, EVE will only provide the green/yellow quality control report from the cell production line.
Additionally, EVE cannot file for a dangerous goods export certificate once the cells leave their facility and go to a third party facility in China for processing. That third party facility will be the one required to file for a dangerous goods export certificate or what is often the case, they will choose to ship the cells undeclared and illegally (duty free AKA special line).
In our experience, once you introduce a third party facility to apply spec result stickers, custom logo packaging and weld onto your cells, it opens the door for many bad possibilities.
The cells we offer have not been handled by ANYONE besides EVE Energy and us ensuring 100% certainty you will get the Grade A cells you are expecting with 10+ years design life!
Our EVE LF280K cells are shipped to us in wooden crate pallets which provide the greatest level of protection during the long sea freight process.
We are able to offer the cells in these crates for larger purchases.
*Please note they come 40pcs per crate.
For smaller orders, we will repackaged into custom foam packaging we have designed. This ensures for a safe transit during the domestic shipping process.
