3. Electrical Characteristics & Test Condition
Testing Conditions: Ambient Temperature: 25±5℃; 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.
|3.1||Normal Capacity||100Ah||After Normal charge, discharge @0.33C current to the end of discharge voltage.|
|3.2||Internal Impedance||≤40mΩ||@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 220Vac, after rectification power module, output 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 life.

5.3 sleep mode
The system would go into low-consumption mode in any of the following conditions:
Before sleep mode, please make sure there is no input voltage, otherwise it can no go to sleep mode.
5.4 wake up
Remark: single model or the whole system goes to low-consumption mode after over discharge protection, it would be wake-up every 4hs, to open discharge MOS. If it can be charged, it would exit sleep mode and start normal charge; if it fails to be charged after 10times of wake-up automatically, there would be no automatic wake-up.
