- Self-discharge occurs in the lithium-ion battery. If you store mBot2 Shield with the battery voltage lower than 3.6 V for a long time, the battery will be over-discharged and its internal structure may be damaged, which reduces the endurance of the battery. Therefore, to store mBot2 Shield for a long time while keeping the battery intact, you need to charge the battery once every three to six months to 3.8–3.9 V (the best voltage for storage is 3.85 V), which allows the discharge depth of 40% to 60%.
- Store mBot2 Shield at 4℃ to 35℃ in a dry place or keep it away from moisture through packaging.
- Keep it away from heat or direct sunlight.
Programming
You can use mBlock 5 to program mBot2. mBlock 5 provides two editors, namely the block-based graphical editor (the default editor, referred to as mBlock 5) and Python editor (referred to as mBlock-Python Editor).
For details about programming, see "Program mBot Neo with mBlock 5."
