BYD C13 125 Ah Prismatic LiFePO4 Cell, Used/Tested

Lithium Performance, Lead Acid Price

These BYD lithium iron phosphate (LiFePO4) cells offer outstanding performance at a rock-bottom price. Weighing in at only 3.45 kg (7.6 lb), they fit far more capacity than lead acid in the same volume. In fact these have an outstanding energy density of 19 pounds per kilowatt-hour. They can operate for thousands of cycles at 80% depth-of-discharge and have a flat voltage curve.

These cells have M8 female terminals. Bolts are included. We also have flexible copper bus bars (1/4" thick x 5/8" wide) available for $1 each, contact us if you need them and we'll add them to your order.

These cells feature a one-way safety valve to release gas and heat. They're certified with UL1642 single-cell standards, and testing such as nail penetration, short circuit, over-charge/temperature/voltage, and dropping has confirmed that they won't catch fire or explode even when abused. Additional certifications include MSDS, UN38.3 and CE.

About These Cells

At Higher Wire, our goal is to turn nuisance waste back into useful assets and maximize the life of every lithium battery. We work with collection centers, OE manufacturers and end users and help them avoid the cost of handling and recycling lithium batteries.

Many of these cells were discarded because of cell imbalances or the failure of one or two cells. We perform a suite of visual and cycling tests to check the state of health of each cell independently. All cells are charged to nominal voltage of 3.2v and checked prior to leaving our facility.

All of these cells have greater than 80% of original capacity and include a limited 90 day warranty. They will show signs of wear or corrosion and may have slight swelling. Warranty does not cover use in higher-drain applications such as golf carts, scooters, e-bikes, EVs, or any application that regularly sees greater than 0.5C (i.e., 50 amps for a 100Ah cell).

Every cell that is not viable for continued use is properly recycled with one of our reputable partners per R2 standards. It costs a little more, but it's money well-spent to close the loop on the lithium battery supply chain.

Safety

Lithium batteries can be potentially dangerous! Even when properly handled, lithium batteries may ignite or explode. It is imperative that you use quality battery management and charging systems when operating lithium batteries. All users of lithium-ion batteries MUST read the warning and safety instructions on our website before using lithium-ion batteries.

Warranty

All of these cells have greater than 80% of original capacity and come with a limited 90 day warranty. If a cell or pack fails within that window, we will replace it no questions asked. Note that the replacement may not have the same capacity as the original purchase, and may be lower capacity. Because these are Second Life, they are not covered for high-drain applications that exceed 0.5C (i.e., 50a for a 100Ah battery). High-drain applications include but are not limited to golf carts, EVs, e-bikes and scooters. See our warranty page for limitations.
