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 LiFePO4-compatible 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.

User Responsibility & Risk Acknowledgment

  • The user assumes full responsibility for proper handling, charging, and storage.
  • Misuse or mishandling may result in serious injury or damage.
  • No guarantee of compatibility with any specific device is provided.
  • Usage of this battery is at your own risk.

By purchasing and using the JGNE 3.2V 26650 4000mAh 11.4A LiFePO4 Battery, you acknowledge and agree to follow all safety guidelines. Failure to comply may result in hazardous consequences. Prior knowledge of LiFePO4 battery safety is required before purchase.

Stay safe and handle responsibly.

Frequently Asked Questions

Find answers to common questions about our products

Yes. All cells we sell are guaranteed authentic, Grade A, and brand new. Not reclaimed, used, or rewrapped. We also prioritize fresh manufacturing dates, so you’re not receiving cells that have been sitting around for years.

Some sellers offer Grade B cells that can have inconsistent voltage, higher internal resistance, reduced performance, or other issues. You will never receive a Grade B, reclaimed, or used cell from us.

These are sold as bare cells (no welded tabs or leads) unless the listing explicitly states otherwise.

To make pack building easier, our cells are sorted and batched for matching internal resistance, voltage, and date code, so they arrive ready to be assembled into a pack.

U.S. orders ship from Atlanta, Georgia.

For international orders outside the USA, we may ship from a different fulfillment hub depending on the product’s manufacturing location, to ensure faster and more efficient delivery.

Shipments within the USA, delivery in 1–3 days (up to 5). Expedited shipping available. International shipping varies—contact us to inquire.
