3. Electrical Characteristics & Test Condition

 

Testing Conditions: Ambient Temperature: 25±5℃ (68℉~86℉); Huminity:45%~75%.

Normal charge:Charge battery under CC(0.33C)/CV(58.4V) mode until over charge protection or the charge current reduce to 0.05C, and then rest for 1h.

 

NO Items Criterion Condition
3.1 Normal Capacity 50Ah After Normal charge, discharge @0.33C current to the end of discharge voltage.
3.2 Internal Impedance ≤50mΩ @50% SOC @1kHz AC internal resistance test instrument.
3.3 Short circuit protection Auto cutoff load when short circuit Connect the positive and negative of this battery pack through a lead with 0.1Ω resistance.
3.4 Cycle life @DOD100% ≥2000 cycles After Normal charge,discharge @0.33C current to the end of discharge voltage. Repeat above process until discharge capacity reduce to 80% of initial value.

5. User guide

 

5.1 TB48XXF-T110X Operation principle and Wiring hint

 

Input AC 220V, after rectification power module, output DC 48V. When the power grid normal, the battery will supply power according to system requirement, and to be charged at same time; when power off, the battery will supply energy, to make sure the DC power system working normally, to realize uninterruptible power supply. The power supply has second disconnection function, when the battery voltage is low, the battery output would be cut off to protect battery.
