Your robot uses lithium-ion polymer (LiPo) batteries. These are similar to those used in laptops, and are small and light for the amount of energy they contain. This is great for your robot but it is vital to treat such a high concentration of energy with respect. If you do not, there is a serious risk of fire and injury. To avoid this, you should follow the safety information on this page closely, at all times.
You must not use any batteries, chargers, bags or cables not explicitly authorised by SourceBots.
- Never leave batteries unattended when they are in use.
- Always place the batteries in the provided bag when not in use.
- If a battery has any cuts, nicks, exposed copper on wires or is bulging to the point of no longer being squishy, contact us immediately.
Disobeying the above warnings greatly increases the risk of damage to your battery, which can have fatal consequences. If you have any questions or doubts, talk to a member of staff immediately.
When your batteries are not actively in use, they should be safely stored. You must disconnect the batteries from all electrical equipment, and place them in the battery charging bag. You should then store the charging bag in a safe location.
To use your batteries, you must connect them to the power board. Do not tamper with the cable or connect the batteries to anything other than the power board (or the charger when charging).
During operation, the battery is protected by over-current protection and a fuse in the power board. If any equipment is short circuited, the over-current protection will activate, protecting the battery. In extreme circumstances the fuse may blow to prevent damage to the battery. This is an important safety feature: do not, under any circumstances, bypass the fuse. It is not user serviceable and if it has blown then the power board must be replaced. If you suspect the fuse has blown then please contact us straight away.
Mechanical damage to a battery can be dangerous, and a puncture or large force applied to a battery causes a serious risk of fire. To avoid this, your battery should be shielded from mechanical damage while you operate it. Secure your battery to your robot, so that it does not move or fall off while the robot moves. You should also build a compartment for the battery to be placed in, so that accidental collisions do not damage the battery.
When the battery has been almost completely discharged, the Power Board will automatically turn off and the LED marked “Power / Flat Battery Indicator” in the diagram will flash red and green. You should immediately disconnect the battery. Flat batteries should be given to a facilitator in exchange for a freshly charged battery.
