Certifications

The manufacturing processes are ISO9001 and ISO14001 approved, and many products have obtained CE, IEC, VDS certificates to ensure industry-leading stability and top-tier reliability.

⚠️ Daily Maintenance Guide

Check the voltage data on the BMS display and the actual battery voltage value to ensure accuracy. If they are inconsistent, proofreading is required (error should not exceed 10mV).
Verify temperature readings of the BMS against actual values; the difference should not exceed 3°C to ensure protections trigger reliably at extreme temperatures.
Check the BMS current readings against actual currents; the variance should stay below 1% to prevent overcurrent risks.
Verify the reliability of your charging equipment to ensure it acts according to regulated BMS current and voltage.
Inspect overall connections of the battery pack periodically to make sure contacts are healthy and free of dust, powders, or metallic debris.

🚫 Important Precautions

Children are strictly forbidden from handling or operating the battery system.
Do not attempt to disassemble the battery cells or pack under any circumstances.
Keep the batteries away from hazardous materials, environments, high temperatures, or corrosive chemicals.
Improper use (like external short-circuits, overcharging) may cause smoke. If smoke occurs, cut off power immediately, evacuate, and utilize carbon dioxide/dry powder fire extinguishers or sand to isolate.
Never short-circuit the positive and negative terminals directly. Avoid any metallic object contact to prevent sparks and injuries.
Do not submerge the battery in water, liquids, or use in environments with humidity levels exceeding 95%RH.
Do not combine different models or battery chemistries in series or parallel loops.

Frequently Asked Questions (FAQ)

What payment methods and delivery terms are available?

Payments are accepted via T/T, Western Union, and PayPal under standard FOB Shenzhen, CFR, or CIF terms. Buyers are responsible for taxes and bank charges in their respective countries.

What is the estimated shipping and dispatch timeline?

Products are typically shipped within 30-60 days following the confirmation of the bank receipt. A unique tracking number along with actual product photos will be emailed as soon as the dispatch is completed.

How long is the design lifespan and expected cycle count of this LiFePO4 battery?

This battery has an exceptional design lifespan of 10 years at a constant 25°C. In terms of usage, it boasts over 6,000 cycles at 80% Depth of Discharge (DOD) before falling below 80% of its original capacity.

Can I configure these batteries in a larger parallel or series battery bank?

Yes. The battery cells and BMS are engineered to support flexible configurations of up to 4 units connected in series or up to 4 units connected in parallel to increase either the voltage or total capacity of your power storage.

How does the integrated Intelligent BMS protect the battery?

The built-in Battery Management System (BMS) automatically protects internal cells against over-charging, over-discharging, over-temperature, and short-circuit conditions. It continuously manages balance among individual cells to maximize performance, safety, and operational lifetime.

What should be done if the battery swells or emits smoke?

Under excessive thermal stress or extreme usage, if smoke occurs, immediately cut off the power supply, evacuate the area, and smother the fire using a carbon dioxide or dry powder extinguisher, sand, or mud. If cell swelling is observed, stop operation immediately and reach out for technical diagnostic assistance.
