Standard Battery Parameters

WHEN ADJUSTING YOUR X2 AC PLUS CHARGING PARAMETERS, BE SURE YOU SELECT THE PROPER BATTERY TYPE AND CELL VOLTAGE FOR THE TYPE OF CELL YOU ARE CHARGING. CHARGING BATTERIES WITH THE WRONG SETTINGS MAY CAUSE THE CELLS TO BURST, CATCH FIRE OR EXPLODE.

Charging

Before charging your batteries, it is critical that you determine the maximum allowable charge rate for your batteries. The X2 AC Plus is capable of charging at high rates that may not be suitable or safe for your particular batteries. For example, Lithium cells are typically safe to charge at 1C, or the total mAh÷1000. A 1200mAh battery would have a 1C charge rate of 1.2 amps. A 4200mAh battery would have a 1C charge rate of 4.2 amps. Some manufacturers are oering Lithium cells that can be charged at greater than 1C but this should ALWAYS be veried before charging a Lithium battery at rates higher than 1C. Voltage is just as critical as the charging amperage rate and this is determined by the number of cells in series, or “S”. For example, a 3S LiPo is rated at 11.1 volts (“S” multiplied by a single LiPo cell with a nominal voltage of 3.7 volts DC. 3 cells x 3.7 volts each equals 11.1 volts DC).

Connect the battery’s main leads to the charger output: red is positive and black is negative. Keep in mind that the gauge or thickness of your charging leads from the X2 AC Plus to your battery must be of an acceptable current rating to handle the applied charge current. For maximum safety and charging eectiveness, always match or exceed the main battery lead rating when assembling or selecting your charging leads. If you charge a battery at a high current rate (amperage) with a charging lead not rated for the chosen amperage, the wire could get hot, catch re, short out and/or potentially destroy your battery and the charger.

Warning

When in doubt, always use a higher gauge wire (lower AWG number). It is common to see charging leads constructed of 14AWG, 16AWG or 18AWG wire.

Always refer to recommendations from your battery manufacturer for your specic battery type and size before initiating a charge or discharge process.

Do not attempt to disassemble or modify Lithium or Lead-Acid battery packs.

Discharging

The X2 AC Plus discharging functions are for two specic purposes:

• Refreshing the capacity of a Nickel-based battery that has lost capacity over

time (NiMH or NiCd).

• Reducing the voltage of a Lithium battery for safe storage.

LITHIUM CHEMISTRY BAT TERY PACKS SHOULD ONLY BE DISCHARGED TO THEIR MINIMUM SAFE VOLTAGE, NO LOWER. DEEP DISCHARGING A LITHIUM CELL WILL DO PERMANENT DAMAGE. REFER TO THE STANDARD BATTERY PARAMETERS TABLE ON PAGE 6 OF THIS MANUAL FOR MINIMUM DISCHARGE VOLTAGES.

LiPo & LiHV Charge/Discharge Cycling

Lithium batteries are known to reach full capacity after a break-in period of about 10 charge/discharge cycles. We do not recommend you use the X2 AC Plus charger to do this; normal use and recharging will achieve the same results. If you wish to perform a Lithium break-in on the bench with the X2 AC Plus, discharging to minimum acceptable voltages and performing a balance charge at 1C maximum rate is recommended. If you choose to break in your Lithium batteries under normal use, charging at only 1C for the rst ten cycles will help ensure full performance and service life from your Lithium cells.

Re-Peak Mode of NiMH/NiCd Battery:

In re-peak charge mode, the charger can peak charge the battery once, twice, or three times in a row automatically. This function is useful for ensuring a full battery charge.

Delta-Peak Sensitivity for NiMH/NiCd:

This automatic charge termination program is based on the principle of the Delta-peak voltage detection. When the battery’s voltage exceeds the threshold, the process will be terminated automatically.

Cyclic Charging/Discharging:

1 to 5 cyclic and continuous charge > discharge or discharge > charge sessions are optimal for battery performance and balancing.

Automatic Charging Current Limit:

You can set the upper limit of the charging current when charging your NiMH or NiCd battery. The ‘AUTO’ charging mode, however, is recommended when charging NiMH batteries with low impedance and capacity.

LiPo Battery Meter:

The user can check the battery’s total voltage, the highest voltage, the lowest voltage and the voltage of each cell.

Battery Internal Resistance Meter:

The user can check the battery’s total internal resistance and the internal resistance of each cell.

Capacity Limit:

The charging capacity is always calculated as the charging current multiplied by time. If the charging capacity exceeds the limit, the process will automatically terminate according to the maximum value previously set.

Temperature Threshold*:

The battery’s internal chemical reaction will cause the temperature of the battery to rise. If the temperature limit is reached, the process will be terminated.

* This function is available by connecting an optional temperature probe which is available as a separate purchase.

Processing Time Limit:

Protect your battery by setting a maximum time limit for charging and discharging.

Operation Program

Description

This charging mode is for charging LiPo/LiFe/LiIon/LiHV battery in normal mode.

This program is for charging or discharging will not be used for long time.

The charging capacity may be less than normal charging but the process time will be reduced.

This mode is for balancing the voltage of lithium-polymer battery cells while charging.

The charger will charge NiMH and NiCd batteries using the charge current set by the user.

Commonly Used Terms Commonly Used Terms [cont.]

Commonly Used Terms:

A, mA:

Unit of measurement relating to a charge or discharge current. 1000 mA

= 1A (A = Ampere, mA = Milliampere).

Ah, mAh: Unit of measurement for the capacity of a battery (Amperes x Time Unit; h = hour). If a pack is charged for one hour at a current of 2A, it has been fed 2Ah of energy. It receives the same quantity of charge (2Ah) if it is charged for 4 hours at 0.5A, or 15 minutes (=1/4 hour) at 8A.

‘C’ - Rating: Capacity is also referred to as the ‘C’ rating. Some battery suppliers recommend charge and discharge currents based on the battery ‘C’ rating. A battery’s ‘1C’ current is the same number as the battery’s rated capacity number, but noted in mA or amps. A 600mAh battery has a 1C current value of 600mA, and a 3C current value of (3 x 600mA) 1800mA or 1.8A. The 1C current value for a 3200mAh battery would be 3200mA (3.2A).

Final Charge Voltage: The voltage at which the battery’s charge limit (capacity limit) is reached after which the charge process switches from a high current to a low maintenance rate (trickle charge). From this point on, any further high current charging would cause overheating and eventual terminal damage to the pack.

Final Discharge Voltage:

The voltage at which the battery’s

discharge limit it reached. The chemical composition of the batteries determines the level of this voltage. Below this voltage, the battery enters deep discharge zone. Individual cells within the pack may become reverse polarized under these conditions, resulting in permanent damage.

Nominal Voltage (V):

The nominal voltage of the battery pack can be

determined as follows:

- NiCd or NiMH: Multiply the total number of cells in the pack by 1.2. An 8-cell pack will have a nominal voltage of 9.6 volts (8 x 1.2).

- LiPo: Multiply the total number of cells in the pack by 3.7. A 3-cell LiPo wired in series will have a nominal voltage of 11.1 volts (3 x 3.7). 4-cell LiHV wired in a series will have a nominal voltage of 14.8 volts. (4 x 3.7).

- Lilo: Multiply the total number of cells in the pack by 3.6. A 2-cell Lilo wired in a series will have a nominal voltage of 7.2 volts (2 x 3.6).

- LiFe: Multiply the total number of cells in the pack by 3.3. A 4-cell LiFe wired in a series will have a nominal voltage of 13.2 volts. (4 x3.3).

- LiHV: Multiply the total number of cells in the pack by 3.7. A 4-cell LiHV wired in a series will have a nominal voltage of 14.8 volts. (4 x 3.7).

If the nominal voltage of the battery is not printed on the battery’s label, consult your battery manufacturer or supplier. Do not attempt to guess the rated voltage of the battery.
