Data Sheet

The BAT+ and BAT- are the power connections and the “bal Bxx” wires are used to monitor the
voltage on each cell. It is strongly recommended to keep equal voltages on each cell during the
charging process. The charger included with ROSbot can charge batteries in the described way
and, thanks to that, the long life of the battery set is possible.
The nominal voltage of each cell is 3.7V but the useful range is 3.2V to 4.2V, so the total voltage
that supplies all ROSbot components is three times greater: 9.6V to 12.6V.
Important notes:
- Avoid deep discharging
Li-Ion batteries shall not be discharged below 3.0V per cell. The recommended lowest
working voltage is 3.2V. User should use appropriate software functions to monitor the
ROSbot battery voltage. This functionality is included in the default ROSbot firmware.
Contact support in case of further questions.
- Unplug charging connectors carefully
You shall not unplug the charger connectors holding the wires. The balancer connection
on ROSbot side has a latching tab (see photo below) that must be pressed before
unplugging. On the charger side there is no latching tab but you should also unplug this
connector holding the white plug.
