the temperature compensation. The compensate rate is 3.3mv/cell, please add it
above the voltage you selected, then you'll have the correct output voltage of charger.
2.2.9 Power Supply Choice
Easy to choose, the BP Series can work as a power supply by dip switch. It is meant that the
output of the battery charger is a fixed voltage. It is not meant for charging batteries. The
battery type and battery temperature are ignored in this mode. The remote battery
temperature sensor does not compensate the voltage, but the battery over-temperature
shutdown is still active. Through this mode, the charger can output neat DC at 13.5V (12V
models) and 27V (24v models)
2.2.10 Built-in Safety
BP Series battery charger provides the following protection features:
1) Unit shutdown if there is a short circuit on output;
2) Electronic protection for reversed polarity;
3) Unit shutdown in event of battery over voltage;
4) Unit reduces output in event of battery charger over temp, and maintain the temp at a balance
level;
5) Unit shutdown in event of battery over temp, and automatic operation reset once the temp
comes down.
2.2.11 Automatic Temperature Compensation
The remote battery temperature sensor is a standard accessory with BP Series battery
charger. With it is plugged to the battery charger, the unit provides a more accurate
temperature-compensated charge for the battery to which the sensor is attached
automatically.
2.2.12 High Ambient Temperature Rated
BP Series charger was designed to work at full load up to 40 ℃.
2.2.13 Protective Lacquer on Each PCB
To protect the PCB from the moisture and corrosion, each BP Series battery charger has
