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.

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.

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.

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.

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!

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.

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.

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.

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.

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.

We(QSO)offer a one-stop solution. After the purchase, our technical team or certified installation partners will provide remote support to ensure a smooth installation and commissioning. The product is designed as modular and ready-to-use, significantly reducing the complexity of installation.

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).

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.

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.
