5.1 LiFePO4 battery pack
Figure 17– LiFePo4 Battery Pack
The battery pack is composed of eight LiFePO4 cells and a protection circuit module.
The whole package is protected with shrinkable tube.
The batteries must be kept clean and dry in order to avoid escape currents. Check
the wear out of the battery wires to prevent short circuits.
The battery can be separated from the robot by taking out the bottom aluminum
protection and unplugging the power supply connector (red and blue wires) and the
charge connector (yellow wire).
It is recommended to have the robot upsidedown to do this process. The battery
weight is 4kg and will fall when the screws are removed.
Recharge the batteries ASAP if fully discharged. Keeping the voltage low for a long
time will greatly reduce the lifecycles.
