BASIC FEATURES OF FOXY Li-ion CELLS:
The nominal voltage of FOXY Li-ion cells is 3.7 V. In operation, the cell voltage must never exceed 4.2 V when charging and must never drop below 3.0 V when discharging. Exceeding these values ​​is highly likely to cause irreversible damage to the battery. For this reason, it is necessary to use special chargers for Li-ion batteries for charging. Failure to follow the correct charging procedure, as well as short-circuiting the cell, leads to overheating of the cell and its damage by the gases generated. In extreme cases, a chemical reaction may start with the risk of cell explosion. Although Li-ion batteries are quite safe when handled properly, do not underestimate this danger.

CHARGING FOXY Li-ion BATTERIES
For charging, always use a special charger designed for Li-ion batteries operating in constant current / constant voltage charging mode. It must be equipped with an automatic device ensuring that the maximum permitted voltage of 4.2 V (+ 1%) per cell is not exceeded. Do not charge FOXY Li-ion batteries with a current greater than 1C; for normal operation, we recommend using currents in the range of 0.5-1C.

In the case of cells connected in a set, we recommend using a balancer with each charge.

We also recommend checking the cell voltage before starting charging. If the cell voltage is lower than 3.3 V, this means that you are overloading and over-discharging them during operation.

Unlike NiCd and NiMH cells, Li-ion batteries do not require initial conditioning, but if you intend to charge the set with a current of 1C, we recommend not exceeding a current of 0.5 C for the first three charging cycles. Li-ion batteries also do not need to be discharged before charging - for example, you can charge batteries that are 50% discharged.

OPERATION OF Li-ion BATTERIES
Only use devices adapted to be powered by Li-ion batteries. Try to avoid heavy loading of batteries if they have less residual charge than about 20-25% of the nominal capacity (less than 3.3 V per cell). Li-ion cells of any brand are sensitive to overload in this area, which leads to a shortening of their service life.

Protect the receiver battery from vibrations and other shocks and jolts that may occur during the operation of RC models by wrapping it in foam rubber or similar material. Mount it in an easily accessible place on the model, but where it will be protected from the penetration of fuel, exhaust fumes and other operating fluids or water.

STORAGE
Batteries are stored in a partially charged state, the voltage on the cells should be in the range of 3.80-3.85 V. If they are stored out of operation for a longer period, check the batteries and recharge them to storage voltage at least every 3 months.
