Associated hazards and risks

Deep discharge

If the voltage drops below ~3.0 V/cell, the battery is irreversibly damaged.

It may become unusable or dangerous when recharged.

Overcharging

Above 4.2 V/cell there is a risk of swelling, toxic gas leakage, fire or explosion.

Charging should only be done with a Li-Po charger with a balancing function.

Too high current (above the C limit)

If the replica requires more current than the battery can deliver, it heats up excessively.

Internal short circuit and fire may occur.

Mechanical punctures or impacts

Physical damage to the cells can lead to violent chemical reactions → instant flame.

Inappropriate temperature

>60 °C: rapid degradation, risk of explosion.

<0 °C: low performance, risk when charging.

Unattended charging

There have been cases of fires during charging.

Charging must be done under supervision and in a fireproof bag (Li-Po bag).

Storage and safety when not in use

Do not leave the battery fully discharged; the voltage should be within the recommended range (~3.8 V/cell for storage).

Do not leave the battery connected to the replica when not in use. Even if the replica is turned off, "parasite" consumption can discharge the battery below the safe limit.

Store the battery in a cool place, away from fire and, ideally, in a fireproof bag.

Damaged, swollen or deformed batteries should not be used.

Safety recommendations

Use only dedicated Li-Po chargers with balancing.

Check and maintain the appropriate charge level for storage.

Do not expose the battery to water, shock or short circuits.
