• Are you thinking of building a battery?
• You will need these jumpers.
• New batteries/batteries are partially charged at the factory.
• Operation of batteries/batteries is only possible with protection circuits. Without the use of protection circuits, balancers and BMS, permanent damage to the batteries will most likely occur.

Wide range of applications for the EVE C40 LiFePO4 battery

The EVE C40 lithium battery is rechargeable and ideal for universal use. For example, it is suitable for flashlights, e-cigarettes, electronics, e-bikes and e-scooters. Its compact size and high energy density make it ideal for mobile and portable devices.

Flexible battery systems

These batteries can be easily stacked in seriesfor higher voltage. Using 4 pieces will give you a 12V system, 16 pieces will create a 48V system. This flexible approach allows for easy customization to your specific needs.

Advantages of LiFePO4 technology

EVE's LiFePO4 batteries feature almost zero self-discharge and have no memory effect, which means they can be recharged at any stage of discharge. They are safer than Li-ion batteries and offer better performance than Ni-Cd, gel or conventional lead acid batteries.

LiFePO4 EVE C40 battery safety and protection

EVE C40 batteries can be discharged to a maximum of 2.5V and charged to 3.65V. It must be ensured that the cell voltage never exceeds these limits, otherwise they will be irreversibly damaged and the capacity will be reduced. Protection against undercharging and overcharging must be provided by suitable electronics. Each cell is provided with a pad for easy connection to other cells by soldering or a special spot welder.
