KAVAN Li-Fe 6.4 V / 2900 mAh RX

Kavan lithium-phosphate (LiFe) batteries for RC receivers are an ideal source of power for on-board electronics in RC models of all kinds - directly using receivers and servos designed for voltages higher than 6 V or with a suitable UBEC power stabilizer with 5 V output for classic receivers and servos. They are characterized by high energy "density" providing high capacity with relatively low weight and small size; they are more mechanically resistant and less prone to damage than conventional "bag" LiPo batteries. Thanks to the advanced technology used in the manufacture of the electrodes, they enable fast charging - with long life and a favorable purchase price.

BASIC FEATURES OF KAVAN LiFe ARTICLES:

The nominal voltage of LiFe cells is 3.2 V. During operation, the cell voltage must never exceed 3.6 V during charging and must not drop below 2.5 V during discharging. Exceeding these values can cause irreversible damage to the battery. For this reason, special chargers for LiFe batteries should be used 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 resulting gases. In extreme cases, the chemical reaction can involve the risk of exploding the cell. LiFe batteries are safe if handled properly, do not underestimate this danger.

CHARGING KAVAN LiFe BATTERIES

Always use a special charger designed for LiFe batteries for charging. It must be equipped with automation to ensure that the maximum allowable voltage of 3.6 volts (+ 1%) per cell is not exceeded. Do not charge KAVAN LiFe batteries with a current higher than 1C *, we recommend using currents in the 0.5-1C range for normal operation. We recommend using a balancer for each charge.

We also recommend checking the voltage of the individual cells of the kit before charging. If the voltage of the cells is lower than 2.8V, it means you are overcharging them and overcharging them during operation.

Unlike NiCd and NiMH cells, LiFe batteries do not require pre-forming, but if you intend to charge kits at 1C, we recommend not exceeding 0.5C for the first three charging cycles. LiFe batteries also do not need to be discharged before charging - you can, for example, charge batteries that are 50% discharged.

OPERATION OF LiFe BATTERIES

Use only equipment designed to work with LiFe batteries. Try to avoid placing heavy loads on batteries if their remaining charge is less than about 20-25% of rated capacity (less than 3.0 volts per cell). LiFe cells of any brand are sensitive to overcharging in this area, leading to shorter life.

Protect the receiver battery from vibration and other shocks and bumps that can occur during RC model operation by wrapping it in foam rubber or similar material. Mount it in an easily accessible place on the model, but protect it from the ingress of fuel, exhaust and other operating fluids or water.

STORAGE

Batteries are stored in a partially charged state, the voltage on individual cells should be between 3.30-3.35 V. If the batteries are stored for a long time, they should be checked at least every 3 months and charged to the storage voltage.
