48V (51.2V) 100Ah 5120Wh LiFePO4 Rack Battery with Active Dynamic Balancing,10 Years Warranty, 5000+ cycles life

Key Parameters that are Communicated:

Total battery string voltage, battery string capacity (SOC), battery string health status (SOH), battery voltage, battery strings, charging /discharging current, and number of battery string cycles (If the discharge exceeds 80% of the nominal capacity, the value is 1 Cycle), cumulative discharge capacity, maximum and minimum battery voltage, ambient/battery string temperature (four battery cell temperatures, one ambient temperature, and one MOSFET temperature), historical data.

Alarms and Protection Status’:

Protection function status, battery string charging/discharging status, total battery string high voltage alarm, total battery string low voltage alarm, Battery overvoltage alarm, battery undervoltage alarm, battery string short circuit alarm, battery string overvoltage/overcurrent alarm, battery string undervoltage/overcurrent alarm, battery string low capacity alarm, battery string polarity reverse connection alarm, battery high/low temperature alarm, ambient high/low temperature alarm, MOSFET temperature alarm, battery string low capacity alarm, and cell failure alarm.

Remote control:

Protection function status, alarm sound on/off, intelligent intermittent charging mode, current limiting charging mode, charging on/off, discharge start/stop, etc.

Various other functional states and parameter setting range, BMS and switching power, system output performance and matching parameters.

Reset button

• When the BMS is in a dormant state, press the button for 1 second and then release it. The protection board will be activated, and the LED indicator lights will start from “L4” for 0.5 seconds.
• When the BMS is in an active state, press the button for 3 seconds and then release it. The protection board is dormant, and the LED indicator lights will turn on for 0.5 seconds from “RUN”.

Buzzer Action Description

• When a fault occurs, the sound is 0.25 seconds every 1S.
• When the BMS is protecting, a chirp will sound for 0.25S every 2S (except for overvoltage protection).
• When an alarm is generated, the alarm buzzes for 0.25S every 3S (except for the overvoltage alarm at end of charging cycle). The buzzer function can be enabled or disabled by via the computer interface, but is disabled by factory default.

Sleep function

When any of the following conditions are met, the system enters the low-power mode:

• Cell or overall over-discharge protection is not removed within 30 minutes.
• The minimum cell voltage is lower than the hibernation voltage of 3300mV, and the duration reaches the hibernation delay (The default value is 500 seconds. No communication or current is required).
• Standby time exceeds 1 hour (0.5 to 2 hours can be configured) (no communication, no charge / discharge, and no charger is connected).

Before hibernation, ensure that no external voltage is connected to the input terminal, no external communication is available, and the on / off button is not pressed. Otherwise, the low-power mode cannot be entered.

When the voltage of any unit is lower than the undervoltage protection value of 500mV, the BMS will enter the ultra-low voltage sleep after 1 min.
