Frequently Asked Questions (FAQs)
Here are answers to the most common questions from our wholesale and business clients.
General & Certification
Q1: What does "Grade A" mean for your LiFePO4 cells?
A: "Grade A" indicates cells that meet the original manufacturer's highest standards for capacity, voltage consistency, internal resistance, and cycle life. They are not B-grade, recycled, or used cells. We provide full test reports to verify performance.
Q2: Are these cells certified (UL, CE, RoHS, UN38.3)?
A: Yes. Our cells are sourced from factories with relevant certifications. They comply with RoHS and are tested to meet UN38.3 standards for safe transportation. Specific factory certifications (like UL 1642) can be provided upon request for OEM projects.
Technical Performance
Q3: What is the expected lifespan in a solar storage system?
A: Under typical solar cycling (0.5C charge/discharge, 80% Depth of Discharge, at 25°C), these cells are rated for >4000 cycles to 80% of original capacity. This translates to over 10 years of daily use in well-managed systems.
Q4: How do these cells perform in cold temperatures?
A: LiFePO4 performs well in cold, but charging below freezing requires caution. Our cells can discharge in temperatures as low as -20°C. However, charging below 0°C without a battery management system (BMS) with low-temperature cutoff is not recommended, as it can cause permanent damage.
Q5: Can I connect these cells in parallel to increase capacity?
A: Yes. Connecting cells in parallel (positive to positive, negative to negative) increases the overall amp-hour (Ah) capacity. It is critical to use cells from the same batch with closely matched voltage before connecting and to employ proper fusing.
Shipping, Logistics & Warranty
Q6: What is the lead time for a wholesale order?
A: For standard orders, lead time is typically 10-20 business days after order confirmation. For large container loads or customized orders, our sales manager will provide a precise timeline.
Q7: What documents are provided with shipment?
A: We provide all standard export documents: Commercial Invoice, Packing List, Bill of Lading/Airway Bill, and a Material Safety Data Sheet (MSDS) and UN38.3 Test Summary required for shipping lithium batteries.
Q8: What is your warranty policy?
A: We offer a strong 5-year warranty against manufacturing defects. The warranty covers capacity fade beyond specified limits and internal failure. It requires proper usage within published specifications. Please contact us for the full warranty terms.
Application & Integration
Q9: Do I need a Battery Management System (BMS) with these cells?
A: Absolutely. For any multi-cell series or parallel pack, a high-quality BMS is essential for safety and longevity. It protects against overcharge, over-discharge, over-current, and short circuits. We can supply recommended BMS units or assemble complete packs with an integrated BMS.
Q10: How many cells do I need to make a 12V, 24V, or 48V battery?
A: LiFePO4 cells are nominally 3.2V. To create a standard voltage:
- 12V Battery: Connect 4 cells in series (4S).
- 24V Battery: Connect 8 cells in series (8S).
- 48V Battery: Connect 16 cells in series (16S).
You can then connect these series strings in parallel to increase capacity (e.g., 8S2p for a 24V 100Ah battery).

DoD describes how much of the battery's capacity has been used. A DoD of 100% means the battery is completely empty, while 0% means it is full.
SoC reflects the battery's charge level. A SoC of 100% means the battery is full, and 0% means it is empty.
C-rate, or power factor, indicates how quickly a battery can be charged or discharged relative to its capacity. A rating of 1C means the battery can be fully charged or discharged in one hour.
The battery uses Lithium Iron Phosphate chemistry and provides a cycle life of over 6,000 cycles at 90% Depth of Discharge, and over 10 years at one cycle per day.
kW (kilowatt) is a unit of power, measuring the rate of energy production or consumption. kWh (kilowatt-hour) is a unit of energy, measuring the total amount of work done or energy used over time.
EGbatt home batteries are suitable for both indoor and outdoor installation (depending on the model's protection level) and offer floor-standing or wall-mounted options. Common locations include garages, attics, or under eaves.
This depends on the load. As a realistic example, a 10kWh battery could run ten 100-watt light bulbs for 12 hours without recharging.
The number varies based on home size, energy consumption history, and personal goals (like which devices to run during an outage). For most systems, 2 or 3 batteries are installed. A detailed discussion of your needs is recommended for an accurate assessment.
Yes, it is possible, but it requires careful planning and significant investment. A true off-grid system needs a large enough solar array and sufficient battery storage to sustain your lifestyle. Cost and having an alternative energy source for when solar charging isn't possible are key considerations.
No. EGbatt focuses on building long-term relationships with business partners like battery distributors, solar equipment dealers, and installation contractors worldwide, not direct sales to end consumers.
