Freight LTL Shipping to Lower 48 USA states only via Ground Shipping. No shipping to PO Boxes. No international shipping including Hawaii, Guam, Puerto Rico. These modules are brand-new and carefully designed without spot welding. They are assembled at a 52V nominal voltage, making them compatible with most 48V inverter systems. The cells are reinforced with fiber tape and encased in clear shrink tubing for enhanced protection and durability. Originating from a large-scale government project that was discontinued, we have a substantial inventory available—perfect for bulk orders, so feel free to reach out if you need higher volumes. Each module incorporates custom PCB busbars, offering excellent performance and reliability. They've been rigorously tested to handle up to 1000A for two minutes, ensuring they deliver impressive power output. These need to be shipped in a pallet so freight shipping is required and will be billed after order is placed.  LTL shipping for 1 - 4 modules  starts at around $300 to western usa destinations  and goes up to $550  to East coast addresses so it makes sense to order multiple modules to get best shipping.   If you need less than 45 cells you can purchase them here.  Shipping charges example: 1 module 200Lbs  To FL   - $4682 Modules 400Lbs  to FL =  $5003 Modules 600Lbs to FL  = $5464 Modules 800Lbs to FL = $546 Typical Capacity: 256Ah , 13.3kWhLength: 22"  InchesWidth:  15.5" InchesHeight: 10"  InchesWeight: 200 PoundsPower: 1000A (120 seconds)Voltage nominal: 52.4 VCharge voltage cut-off: 58.8v   (4.1 V/cell)Discharging cut-off: 42v dc (3.00 V) Get loose cells here
