Special instructions for discharging LiPo batteries
A continuous current of approx. 15 C is no major problem for the LiPo batteries. For larger
currents, please refer to the information in the respective product data sheets. A discharge to
below 2.5 V per cell permanently damages the cells. Avoid this deep discharge unconditionally! It
is essential to switch off the motor before you notice any loss of power. Then LiPo batteries
would already be damaged. Therefore, leave a remaining capacity of approx. 20 % in the battery
for safety reasons. If individual cells were to be fully charged differently, the regulator's low-
voltage cut-off might be too late, so that individual cells could be deeply discharged. Avoid short
circuits. A short circuit causes a very high current to flow which heats up the cells. This leads to
electrolyte loss, gas leakage or even explosions. Due to the danger of a short circuit, avoid the
proximity of conductive surfaces or contact with LiPo batteries. Permanent short-circuits lead to
destruction of the battery, high temperatures and possible spontaneous ignition can be the result.
The batteries must never reach temperatures above 70° C during discharge. Provide cooling or
lower discharge. You can easily check the temperature with an infrared thermometer.
Stability of the battery housing foil
The foil of the aluminium housing can easily be damaged by sharp objects such as needles,
knives, nails, motor connections, soldering or similar. Damage to the foil will render the battery
unusable. The battery must therefore be installed in the model in such a way that the battery
cannot be deformed even in the event of a crash. If the battery is short-circuited, it could burn.
Temperatures above 70° C can also cause leakage of the housing. The battery becomes
unusable due to electrolyte loss. Add defective cells individually packed in poly bags or foil to the
hazardous waste.
Mechanical shock
The LiPo batteries are not as mechanically stable as batteries in metal cases. Avoid mechanical
shocks by dropping, hitting, bending, etc. Therefore, you must never cut, tear, deform or drill the
laminate film. Never bend or twist LiPo batteries. Do not apply pressure to the battery or
terminals.
Handling of the connections
The LiPo connectors are not as robust as other batteries. The aluminium (+) connection in
particular can easily break off. Never use damaged cells: Never use damaged cells. You can
identify damaged cells by one of the following methods: Damaged housing packaging,
deformation of the battery cells, smell of electrolytes, leaking electrolytes. In these cases, further
use of the batteries is no longer permitted. Dispose of them.
