Question 9

Is this battery safe? Could there be a risk of fire or explosion?

Accepted Answer

The most stable lithium iron phosphate battery has been adopted. Its thermal stability far exceed that of other types of batteries. From the very beginning, it significantly reduces the risk of thermal runaway. The built-in intelligent BMS (Battery Management System) of the battery provides multiple hardware-level protections against overcharging, overdischarging, overcurrent, short circuit and high temperature. It has also passed strict certifications such as CE/ROHS/MSDS/UN38.3 to ensure safe.

Question 10

Is it necessary to use BMS? What specific protective measures does the battery management system (BMS) provide for the battery?

Accepted Answer

BMS provides overcharge protection to prevent damage to the battery cells, overdischarge protection to avoid deep discharge and battery damage, overcurrent and temperature protection to prevent circuit overheating (for example, 0°C - 45°C during charging), and automatically intervenes when the temperature is too high. Battery balancing: ensures that the voltages of all battery cells remain consistent, thereby extending the overall lifespan of the battery.

Question 11

What is the after-sales process if there is a problem with the battery?

Accepted Answer

We have a clear after-sales process: 1:Contact our customer service by email or phone and describe the problem phenomenon. 2:Our technical support team will conduct a remote diagnosis and guide you on simple troubleshooting.3. If it is determined to be a quality issue, overseas warehouse return and exchange services will be provided.For non-human-caused problems within the warranty period (accidents and the like are usually not covered by the warranty), we will bear the repair costs.

Question 12

What about after-sales service and maintenance? Who is responsible if there is a problem?

Accepted Answer

We offer clear warranty policies and a localized technical support network. In case of any issues, quick responses can be provided via hotline or online support. When necessary, professional technical engineers will be arranged for 1-on-1 special handling.

Question 13

What about the delivery time and shipping?

Accepted Answer

some of times in stock, we can make 3-7days fast delivery. For USA,Canada,Austraila and most of European country , we provide tax included services, door to door, once you place an order ,then you will receive your new battery pack in about 40-55 days at your home! We also have Oversea warehouse service, 3-7days arrive, no tax fees, please contact with our sales !

Question 14

Why would professional/technical customers choose 3.2V 314AH lithium iron phosphate lifepo4 batteries?

Accepted Answer

The battery can withstand a continuous maximum discharge current of up to 314A, thanks to its extremely low internal resistance design (less than 0.25 milliohms). The amount of heat generated during ultra-high power output is minimal, and its stability and safety far exceed those of ordinary batteries.
A 48V system with 16 series-connected cells, a discharge current of 314A, means it can support a maximum instantaneous power output of over 16 kilowatts. You can easily drive high-power inverters.

Question 15

Compared to the traditional 280Ah system, can using your updated high-capacity battery cells (such as 314Ah/587Ah) help reduce costs?

Accepted Answer

The new generation products (such as 314Ah) can help achieve lower cost per unit of electricity (LCOS). The specific savings ratio needs to be calculated based on the project.

Question 16

What are the advantages of the DIY 48V module?

Accepted Answer

Significant cost savings, extremely high customization flexibility, self-customization of capacity and shape size, performance customization, in-depth understanding and learning, process experience and sense of achievement, controllability and repairability of components.

Question 17

3.2V LiFePO4 Cell's Related Product Advantages

Accepted Answer

Ultra-long lifespan and economic efficiency; Outstanding safety performance; Strong environmental adaptability; Environmental friendliness and convenience. Unmatched Cycle Life: Enjoy over 4000~12000 cycles at 80% Depth of Discharge (DOD), significantly outperforming lead-acid batteries. This translates to more than 5-10 years of reliable service, reducing long-term replacement costs and providing exceptional value.

Question 18

Which trade terms do you support? What about the delivery time and shipping?

Accepted Answer

Supports various trade terms like EXW, FOB, CIF, DDU, and DDP.Most of the products are available in stock at overseas warehouses, we can make 3-7days ddp fast delivery. For USA,Canada,Austraila and most of European country , we provide tax included services, door to door, once you place an order ,then you will receive your new battery pack in about 40-55 days at your home! We also have Oversea warehouse service, 3-7days arrive, no tax fees, please contact with our sales !

Question 19

Question 20

How many battery packs can be connected in parallel at most? How can I calculate the capacity I need when making a purchase?

Accepted Answer

It supports 16 parallel connections, offers free scheme design and capacity planning suggestions to help customers assess their own needs (average daily electricity consumption, maximum load power, electricity price policies), and builds your home photovoltaic renewable energy system.
Modular design supports parallel expansion + compatibility with mainstream photovoltaic systems + intelligent EMS automatically optimizes power usage strategies,(Self-consumption / Peak-valley arbitrage).

Question 21

Can this battery be compatible with my existing solar inverters (such as brands like Victron, Deye, Growatt, etc.)?

Accepted Answer

Yes, the compatibility is very good. This battery supports CAN/RS485 communication protocols, and has preset communication protocols with mainstream inverters in the market (including but not limited to Victron, SMA, Deye, Growatt, Goodwe). Before purchasing, please inform us of the brand and model of your inverter, and we can assist you in confirming the compatibility and completing the matching settings before shipment.

Question 22

How do you ensure cell voltage consistency during the matching process for 14Ah/330AH Lifepo4 cells ?

Accepted Answer

QSO uses high-precision OCV (Open Circuit Voltage) testers with an accuracy of 0.1mV. We only match cells that have been stabilized in our climate-controlled aging room for at least 72 hours. This eliminates 'false' voltage readings caused by surface charge. For wholesalers, this means the cells you receive can be assembled into packs immediately with minimal top-balancing required, saving hours of labor cost and ensuring a perfectly balanced system from the first charge cycle.
