Commonly Used Terms

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).

Commonly Used Terms [
cont.]
- 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
Note
or supplier. Do not attempt to guess the rated voltage
of the battery.
