Battery
-
Keep the battery pack away from children.
-
Be careful when handling battery packs with high cell counts. It is essential to ensure good insulation, there is a risk of electric shock.
-
Do not allow leaking electrolyte to come into contact with fire, it is highly flammable and can ignite. In the event of an explosion or fire, never extinguish the batteries with water. Only extinguish with dry extinguishing agent (sand, etc.) or smother the flames by covering.
-
The electrolyte liquid should not get into the eyes, if it does, wash it out immediately with plenty of clean water and then consult a doctor.
-
The electrolyte fluid can also be washed off clothing and other objects with plenty of water.
-
Do not expose lithium batteries to excessive cold or heat and direct sunlight. Do not heat the battery, throw it into a fire or place it in the microwave. Charge and store batteries in a fireproof container or lithium safe (e.g. AN-262582).
-
Do not subject battery to pressure or impact, deform or throw. Protect from accident or fall. Never use damaged batteries and dispose of them properly.
-
Never place the charger or connected batteries on flammable or conductive surfaces. Never operate in the vicinity of flammable materials or gases. Charging the battery in the model can cause the model to burn down in case of a defect! Do not leave the battery unattended during the charging-discharging process or during operation.
Read the charger instructions carefully before charging. -
Do not charge batteries which are strongly heated or undercooled. Allow batteries to cool down to approx. 20-30°C or warm them up before charging.
-
Only cells of the same capacity and make may be charged together.
-
Make absolutely sure that the polarity of the batteries is correct and prevent short-circuits, especially through non-insulated connector systems.
-
In case of contact with water or penetration of moisture into the battery, there is a risk of explosion due to short-cir-cuiting.
-
Do not charge with reverse polarity.
-
Do not solder directly to the battery.
-
Do not modify or open battery.
-
Do not charge batteries above 4.2 volts (+/-0.05V) per cell and do not discharge below 3 volts per cell.
-
Charge batteries only with suitable lithium battery chargers with connected or built-in equalizer/balancer, never connect directly to a power supply.
-
Do not use the battery in locations subject to high static discharge.
-
All this can cause the battery to be damaged, explode or catch fire.
-
Never charge batteries unattended!
-
Never charge, store or keep the battery in the model or inside a car.
Charging procedure
Only use chargers that have been expressly approved by the manufacturer for
use with lithium batteries. Lithium batteries can only be charged using the
CC-CV charging procedure. Make sure that the charger is correctly selected. In
the first charging phase, the charger keeps the charging current constant.
With a charging current of 1C and a discharged battery, this first phase takes
approx. 50- 60 minutes. A battery capacity of approx. 80-90% is charged. When
the end-of-charge voltage of 4.2 volts/cell is reached, only the voltage is
kept constant and the charge current drops. A further 35-40 minutes are
required to charge the remaining capacity. If the value reaches the lower
current limit of approx. 5-10% of the specified charging current, the charging
process is switched off by the charging device. At a charge rate of 1C, this
means that the entire charging process takes approx. 90 minutes when the
battery is discharged. A lower charging current of 0.3-0.5 C is recommended
for the first charging process. This measure facili-tates balancing and
increases the service life of the battery.
Voltage sensor cable
Due to different cell temperatures during the discharge process, the
individual cells gradually acquire different char-ge states and voltage
levels. The total charge voltage applied is then not distributed evenly across
the individual cells, which means that cells with a higher voltage level can
be overcharged.To measure the individual cell voltage, the lithium batteries
have a separate plug connection (voltage sensor cable), from which a cable
leads to each indi-vidual cell.The black cable (Pin1) is the negative terminal
of the first cell, Pin2 the positive terminal. The next contact in each case
is the respective positive pole of the subsequent cell.
Connect the voltage sensor cable to the Equalizer/Balancer connector on the
charger for charging, which conveniently and automatically brings all cells to
the same voltage value at the same time.
In addition, the voltage of each individual cell is monitored.
Technical data:
- Rated voltage: 3.7 volts/cell
- Low charge rates protect the battery,
- high charge rates reduce the number of cycles by approx. 10%.
- End-of-charge voltage: 4.2 volts/cell (to be maintained to within 0.05 volts)
Discharge rate/discharge current:
Depending on battery type, e.g. a 25C battery can be discharged at a constant rate of 25C (25 times the rated capacity in Ah), and for a short time (for 3 seconds) up to 50C (twice the constant discharge rate). Examples:
- 25C (discharge rate), means capacity value x C rate = discharge current.
- 25C-battery with 1000mAh (1Ah) x 25C = 25A discharge current continuous/50A short time
- 30C battery with 1000mAh (1Ah) x 30C = 30A discharge current duration/60A short-term
- 45C battery with 1000mAh (1Ah) x 45C = 45A discharge current duration/90A short-term
End of discharge voltage:
Lithium cells should be disconnected under load, at the latest at about 3
volts /cell. If the voltage falls below the limit, the cell may be destroyed,
explode and start to burn.
Maximum temperatures
- Charging: +45°C, discharging +60°C
Temperature behavior
- Lithium cells have a distinct temperature curve.
At temperatures below 10…15°C the removable capacity is significantly lower than at 20…35°C. Even at higher temperatures (above 35…40°C) the removable capacity is noticeably lower.
The maximum external cell temperature should not be exceeded during both charging and discharging, otherwise the cell will suffer permanent damage in the form of capacity loss. If exceeded for a longer period of time, it will be destroyed and may explode and start to burn.
Self-discharge:
Lithium cells have an extremely low self-discharge rate (about 0.2% per day)
and therefore can be stored for long periods without problems. If the voltage
drops below 3 volts/cell, it is essential to recharge.
Deep discharge must be avoided, otherwise the cell will suffer permanent
damage in the form of capacity loss and render the battery pack unusable.
Storage:
Before longer storage, the batteries should be charged to the storage voltage
of approx. 3.8…3.9 volts/cell. After approx. 3-5 months they should be
recharged. Never store or keep fully charged but only fully charge immediately
before use. Store batteries in a fireproof lithium safe or tested lithium bag.
Store and keep at room temperature (17-22°C).
Lifetime:
The theoretical life of a cell at low discharge currents, is approximately 500
charge/discharge cycles. At medium discharge currents, the lifetime is lower
and is only about 300 cycles. At high discharge currents, the number of cycles
is in the range of 150-200 cycles. At very high discharge currents even
significantly lower.
After that, the battery is used up and must be disposed of. If the lithium
batteries are only discharged to approx. 70-75% during operation, they will
thank you with a longer service life. Stop operation before a noticeable loss
of power becomes apparent. Disconnect the battery from the load after
operation to avoid further discharge.
Memory effect, cell capacity
Since lithium cells have no memory or lazy-battery effect, the discharge
charge (cycling, matching) required for NC and NiMH batteries is not
necessary. Discharging before charging should also be avoided. Since the
capacity of the lithium battery decreases slightly with each charge, this
would cause unnecessary loss of capacity to the cell.
Interconnecting battery packs
Interconnecting lithium cells in series or parallel to increase voltage or
capacity is problematic because of the diffe-rences in charge voltage and
capacity. Only selected cells can be connected together to form a battery
pack. For our lithium battery packs, only selected cells are connected
together to form a battery pack.
Disposal of rechargeable batteries
Never dispose of rechargeable batteries in the household waste. To protect the
environment, give defective or used batteries only discharged to the
appropriate collection points. These are all sales points for batteries and
recharge-able batteries, or municipal special waste collection points. To
avoid short circuits, please tape off any bare contacts with adhesive tape.
Disclaimer
Since MODSTER cannot supervise the handling of the batteries, any liability
and warranty is excluded.
