Poland Eu Stock Lifepo4 315Ah Prismat Lithium Ion Battery 10000 Cycle Life 315 Ah Amp Lf330 315A 3.2V 330AH Powland Bateria Cell

At QSO, Every 314Ah/315AH/330AH cell comes with a fully intact,unscratched QR code.This allows you to trace the production date and factory test reports via professional third-party software or original factory systems. we provide a complete transparency report showing internal resistance≤0.25mΩ and capacity above 314Ah.This is crucial for long-term stability in high-demand ESS projects where cell consistency is the primary safety factor for preventing unbalanced battery strings.

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 314AH/315AH (Grade A) is engineered for 8,000 to 10,000 cycles at 0.5C/0.5C charge-discharge rates before reaching 80% SOH (State of Health). In a typical daily home energy storage scenario (1 cycle/day), this translates to a lifespan of over 15-20 years. To achieve this, qiso ensures that all cells are strictly matched for internal resistance within a 0.05mΩ delta, significantly reducing the thermal stress during cycling compared to unmatched market alternatives that age unevenly.

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 !

UPS, FEDEX , Post Mail and so on. We can also ship with your own shipping agent. Tracking No. will be offered as soon as your order be shipped out. Before that, our sales will be there to check the packing status, photo you the done order and let you know the forwarder picked it up.

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.

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.
