1. The voltage in above table is at 25
℃
. Please adjust the data according to table 3-3 at
other temperature.
2. Please contact the manufacture about standard for normal power supply or tough
power supply.
3. Above are standard setup parameters in table 3-1. We suggest you to set up end
voltage (LVBD) based on different load current to make the battery life longer. Please
refer to table 3-2.
