Description

Long Life Time 48v 25ah Lifepo4 Battery , Lithium Battery Pack For Back Up Power

1. Deep cycle lithium battery 48V 25Ah advantage

  • Extremely safe and stable chemistry: PCB and/or BMS built inside to balance protect the battery.
  • Long life-cycle: Can be circularly used, best can up to 2000 times recycles, 8 times of Lead acid battery.
  • Lighter weight, with the best power-to-weight ratio: 1/3 of Lead acid battery weight.
  • Good performance at high temperature and high temperature resistance
  • Low self-discharge rate, less than 3% monthly.
  • No memory effects and highly efficient charge.
  • Environment friendly: Clean and Green energy poses no pollution on our environment.

No.ItemsStandardsTesting Methods
1Internal ImpedanceImpedance ≤80mΩUnder 20±5℃ Environment Temperature , the Usage Frequency of Fully Charge( 1KHz) , Use AC Internal Impedance test machine to test
2Nominal Capacity25AhRest for 0.5~1 hour after fully charge, Using electrical loader to connect with the battery output port, and discharge with constant current 0.2C till it can’t discharge. Do the cycle three times, if there is one time that the discharge time is equal or more than 285minute, you can stop.
3Short circuit protectionNONEProhibit output electrode short circuit
4Allowed Maximum continuous charge Current15Acharging with this current for more than 0.5h and the added temperature of battery pack less than 20℃.
5Allowed Maximum continuous discharge Current50ADischarging with this current for more than 0.5h and the added temperature of battery pack less than 20℃.
