7. Battery safety information
Although handling non-rechargeable and rechargeable batteries in daily life is a matter of course
today, there are numerous hazards and problems. Compared with conventional NiMH rechargeable
batteries, LiPo rechargeable batteries have a high energy content. For this reason, it is essential to
comply with safety regulations to prevent the risk of a re or explosion.
Always observe the following safety information when handling batteries.
• Keep non-rechargeable/rechargeable batteries out of the reach of children.
• Do not leave non-rechargeable/rechargeable batteries lying around, as they present a choking hazard
for children and pets. Seek immediate medical advice if a battery is swallowed!

from the remote control to prevent them from leaking and causing damage. Completely disconnect the
drive rechargeable batteries from the speed controller and remove them from the vehicle.
• When handling leaking or damaged non-rechargeable/rechargeable batteries, always use suitable
protective gloves to avoid burning your skin.
• Liquids leaking from batteries are very chemically aggressive. Objects or surfaces coming into contact
with these liquids could be severely damaged. Always store batteries in a suitable location that is not
prone to damage.

Only recharge compatible rechargeable batteries and ensure that you use a suitable battery charger.
• Observe the correct polarity when inserting batteries/rechargeable batteries or connecting drive
rechargeable batteries (observe plus/+ and minus/-).

• The type of charger you require may vary depending on the type of rechargeable battery (NiMH, LiPo....).

• A suitable balancer (usually already integrated in good LiPo chargers) is required to charge multi-cell
LiPo rechargeable batteries. A balancer (often referred to as an equaliser) prevents the overcharging of
a single LiPo cell by checking the individual cell voltages.

• Never charge batteries immediately after use. Always allow them to cool down for at least 5–10 minutes.
• Always remove the drive battery from the model before charging it. Before charging the drive
rechargeable batteries, completely disconnect them from the speed controller.
