Q1. Do you have MOQ (Minimum Order Quantity) Limit?
A: No, Elite do not have MOQ limit, 1 pieces sample order or small quantity is available.
Q2. What about the Lead time?
A: Standard product lead time: Samples: 3-5 days, Bulk order: 3-4 weeks.
Customized product lead time: 3-4 weeks both for sample or bulk order.
US & EU Warehouse Ready to Ship Products Can shipping out once your payment confirmed.
Q3. How do you ship the goods? How about the Shipping time?
A: By air door to door (6-12 days): FEDEX, UPS or DHL, suitable for urgent small order.
By sea door to door (25-50 days): suitable for bulk order.
By sea to delivery port (20-35 days): Suitable for bulk order.
By Air to airport (3-5 days): Suitable for urgent heavy package.
Q4. How to proceed with an order?
A: Firstly, providing your requirements or applications, then we will provide battery solution and quote accordingly.
Secondly, confirming the order and do the deposit for it, then we will arrange the production.
Q5. Is it available to print my logo on the product?
A: Yes. For OEM Demand Just send us your logo and we will make a label for the product. For product with metal/aluminum case, logo silk-print on the case is available.
Q6: Does the BMS have low temperature charging disconnect? A: Yes, of course! If you purchase our battery with low-temperature cutoff,our BMS has low-temperature protection cut-off function to protect your battery from low-temperature damage and extend battery life.
Low temp cut off protection (Charge): 0ºC ± 4ºC (32°F ± 39.2°F)
Low temp cut off protection (Discharge): -20ºC ± 4ºC (-4°F ± 39.2°F)
Q7: Do I have to buy a special charger for LiFePO4 batteries?
A: We recommend using a lithium iron phosphate 4-string (14.6V) charger to charge the battery.Additionally, you have two other options:
Scheme 2: You can use photovoltaic solar panels to charge the battery through MPPT.
Scheme 3: You can use an inverter with a built-in AC to DC charging function to charge the battery pack.
Q8: What is a BMS? A: A Battery Management System (BMS) is responsible for protecting the li-ion cells and the user from unsafe operating conditions, such as low or high voltage, low or high temperatures, and system shorts. It shuts off the battery to prevent damage.Our BMS also ensures cell balance. During each charge cycle, it reduces the charging rate in cells that have been topped off first, allowing other cells to catch up. This maintains cell balance and ensures the quality and efficiency of the battery pack.
Q9: How long do LiFePO4 batteries last?
A: Our LiFePO4 lithium iron batteries provide 4000+ cycles, compared to 300-500 cycles in lead-acid batteries. The service life of LiFePO4 batteries is 8 to 10 times longer than standard lead-acid batteries.
Q10: Are your Batteries safe?
A: Our LiFePO4 batteries are manufactured using automotive-grade LiFePO4 cells, offering higher energy density, no memory effect, more stable performance, and greater power.The stable Lithium Iron Phosphate chemical structure makes LiFePO4 batteries resistant to burning or exploding, even at high temperatures, short circuits, impact, and drops. They have been tested and certified for safety by CE.Our batteries do not contain heavy metals or rare metals, making them more environmentally friendly. They are often referred to as green batteries.All our lithium battery products have a built-in battery management system (BMS) that protects against overcharge, deep discharge,overload, overheating, and short circuit. The BMS also ensures a low self-discharge rate. Furthermore, our BMS has a high-temperature disconnect function. When the internal battery temperature reaches 75°C (167°F), it automatically disconnects to protect the battery. It also disconnects if the overcharge voltage exceeds 15V or the overdischarge voltage drops below 8.8V.
