​
Batteries

Your kit contains one 11.1V 2200mAh LiPo (Lithium-ion Polymer) battery. These batteries are high-energy density cells similar to those used in laptops. While they are lightweight and efficient for robotics, they require careful handling. Kit Equipment:
  • One 11.1V 2200mAh LiPo Battery.
  • One battery charger.
  • One battery charging bag (“LiPo Safe” Bag).
You must not use any batteries, chargers, bags, or cables not explicitly authorized by Robocon Oxfordshire. To request permission for alternative equipment, email support@roboconoxon.org.uk.

Battery Safety

Battery Safety Instructions
  • Never leave batteries unattended while charging or in use.
  • Always use the provided charging bag when charging or storing batteries.
  • Do not charge or use a battery that shows signs of physical damage.
  • Do not tamper with battery wires.
  • If you notice cuts, exposed copper, or bulging, contact us immediately.

​
Storage and Maintenance

When not in use, ensure all batteries are disconnected from electrical equipment and placed inside the provided LiPo safe bag. Store the bag in a cool, safe location.

​
Long-term Storage

If you do not plan to use your batteries for more than a week, charge them to approximately 70% capacity before storage.
  • Why: LiPo batteries have a slow self-discharge rate. Allowing them to over-discharge can cause permanent chemical damage.

​
Operating Batteries

To power your robot, connect the battery exclusively to the power board.
  • Over-current Protection: The power board features an integrated regulator to protect against short circuits.
  • Fuse Safety: A fuse is placed inline with the power cord.
Do NOT, under any circumstances, bypass or replace the fuse. If the fuse has blown then the power board has failed and MUST be replaced for safe operation. If you suspect the fuse has blown then please contact support@roboconoxon.org.uk right away.

​
Mechanical Protection

Punctures or high-impact forces pose a serious fire risk.
  • Secure the battery firmly to the robot chassis.
  • Construct a protective compartment to shield the battery from collision damage.

​
Discharged Batteries

When the battery reaches a critically low voltage, the power board will trigger a low-power shutdown to protect the cells. You should disconnect the battery immediately and begin the charging process.
Do NOT store a discharged battery for more than a few days. Extended storage in a discharged state can lead to irreversible cell damage.

​
Charging

Only use the charger provided by Robocon Oxfordshire.
  1. Connect the battery to the charger.
  2. Place the battery inside the LiPo safe bag.
  3. Keep the battery in the bag until the charger indicates a full charge (all lights turn green).
