NOTE!
Under-voltage protection creates an open circuit, removing voltage from the ter-
minals� With a lead-acid battery, finding no voltage at the terminals often indi-
cates the battery has reached the end of its life� With the LifePo4 module, low
voltage at the terminals typically means the cell protection circuitry has inter-
rupted current to protect the battery module� Simply connect the module to a
charger to restore voltage to the terminals�
OVER TEMPERATURE
A battery module has one temperature sensor to measure every cell bank's
temperature and one PCBA to measure MOSFET temperature�
• The ideal hardware over temperature protection threshold of cell is around
+65°C
• The ideal hardware over temperature protection threshold of MOSFET is
around +85°C
During charging and discharging, when any cell banks temperature >60°C,
software over temperature protection appears, charge and discharges MOS-
FETS turn OFF� When any cell banks temperature < 55°C, over temperature
protection disappear, charge and discharges MOSFETS turn ON again�
When any cell banks temperature > 65°C, hardware over temperature protec-
tion appear, charge and discharge MOSFETS turn OFF� When the temperature
decreases to 55°C, the charge and discharge MOSFETS turn ON again�
BALANCING
Over time, the cells inside a battery pack diverge in both capacity and SOC�
An advantage of the module is the circuitry continuously monitors the capaci-
ty and SOC of each individual cell and balances the battery module to ensure
maximum capacity�
