Advantages of 48V 50Ah LiFePO4 Battery

 

Long Life Warranty

The period of warranty is 36 months from the date of shipment. MAXLI guarantees to give a replacement in case of battery with defects proven due to manufacturing process instead of the customer abuse and misuse.

 

LIFECYCLES (BATTERY LIFESPAN)
Up to 100% capacity for 3,000 cycles in recommended conditions. The typical SLA has 400 cycles. Lithium batteries last so long that the price per use is a fraction of traditional batteries.

 

Smart Built-in BMS

Passive balancing (active balance optional), low voltage cutoff, high voltage cutoff, short circuit protection and temperature protection for increased performance and longer life. Besides, Bluetooth function for option that enables to monitor battery status, such as, voltage, capacity and so on.

 

LiFePO4 Battery Performance and Test Conditions

 

1. Standard test conditions

Test should be conducted with new batteries within one week after shipment from our factory and the batteries shall not be cycled more than five times before the test. Unless otherwise specified, test and measurement shall be done under temperature of 20±5℃ and relative humidity of 45~85%. If it is judged that the test results are not affected by such conditions, the tests may be conducted at temperature 15~30℃ and humidity 25~85%RH.

 

2. Standard Charge/Discharge

Standard Charge: 0.2C

Charging shall consist of charging at a 0.2C constant current rate until the battery reaches 14.6V. The battery shall then be charged at constant voltage of 14.6 volts while tapering the charge current. Charging shall be terminated when the charging current has tapered to 0.05CA. Charge time: Approx 7.0h, The battery shall demonstrate no permanent degradation when charged between 0 ºC and 45 ºC.

Standard Discharge: 0.2C

Battery shall be discharged at a constant current of 0.2C to 10V @ 20º ± 5C
