OEM&ODM

Willys Energy has been building more stable, durable, and efficient power supply solutions. We offer a wide range of lithium iron phosphate (LiFePO4) cell and battery pack, each specifically engineered to deliver a high cycle life and excellent performance over a wide operating temperature. 
 
We will offer various battery based on your application, a wide options on capacity, voltage, size to meet your request. 
 
We manufacture custom lithium iron phosphate battery packs and assemblies for many applications. Our battery design team uses the latest mechanical and electronic design tools to optimize the reliability, safety, and manufacturability of your custom LFP battery packs 
 
LiFePO4 Battery Advantages 
 
LiFePO4 custom battery packs provide excellent thermal stability, very fast charge times, and long cycle life. However, since they operate at a slightly lower voltage than standard Li-ion chemistry, they provide slightly less energy content than other Li-Ion battery packs. Some of the main benefits of utilizing a lithium iron phosphate custom battery pack over other lithium chemistries include: 

● Longer cycle life 

● Increased abuse tolerance

● Faster recharge

● Faster recharge

Lithium iron phosphate battery provide the following features: 
 
Cell Voltage: 3.2V (nominal) 
 
Capacity: 1Ah to 1000Ah+ 
 
Energy by Weight: 90–110 Watt Hour/Kilogram 
 
Energy by Volume: 220 Wh/L 
 
Discharge Characteristics: Power cells are hi-rate capable 
 
Cycle Life: 2000 to 7000 cycles. 
 
Self Discharge: ≤3% month 
 
Temperature Range: -0° C to +60° C 
 
Preferred Charge Methods: CC/CV

Sizes: 18650, 26650, 33700, and large prismatic
 
Lastly, Lithium charging follows a similar charging profile as SLA, Constant Current Constant Voltage (CC/CV). However, lithium can be charged faster, without the need for a maintenance float charge. These benefits make Lithium Iron Phosphate the chemistry of choice for the most demanding applications.
