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 !

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.

Yes, the Lifepo4 314Ah (MB31) and LF280K/280AH share the same physical footprint (173.7*71.7*207.5mm), making them a direct 'drop-in' upgrade for existing 280Ah enclosures. However, because the 314Ah cell supports higher energy density, we recommend ensuring your BMS is rated for the total capacity. This compatibility allows installers and DIYers to increase system energy by 12% without redesigning their physical battery rack structures or cabinets, maximizing energy storage per square foot.

Internal resistance (IR) is the best indicator of cell health.A low IR of ≤0.25mΩ means minimal energy is wasted as heat during operation.More importantly, qiso matches cells within a tight 0.05mΩ tolerance.This prevents the 'bottleneck effect' where a single high-resistance cell causes the entire pack to drift out of balance,triggering BMS protections prematurely.Professional matching is what separates a high-performance 15year battery wall from a 3year failure in complex solar applications.

Our MOQ for wholesale tiered pricing starts at 32pieces,which is one full pallet of cells.For individual DIY projects,we support a MOQ of 4pieces to cover a basic 12V system.Wholesalers who order full container loads(≥1000pcs)can unlock our deepest factory-direct discounts and priority production scheduling.We aim to support both small-scale custom installers and large-scale regional distributors with a flexible MOQ structure that reflects the economies of scale in energy storage manufacture.
