Voltage
Be very careful to choose the correct voltage for different types of battery
otherwise you may cause damage to the batteries. Incorrect settings could
cause the cells to fire or explode.
Never attempt to charge or discharge the following types of batteries.
A battery pack which consists of different types of cells (including different
manufacturers)
A battery that is already fully charged or just slightly discharged.
Non-rechargeable batteries (Explosion hazard).
Batteries that require a different charge technique from NiCd, NiMh, LiPo
or Gel cell
(Pb, Lead acid).
A faulty or damaged battery.
A battery fitted with an integral charge circuit or a protection circuit.
Batteries installed in a device or which are electrically linked to other components.
Batteries that are not expressly stated by the manufacturer to be suitable
for the currents the charger delivers during the charge process.
Please bear in mind the following points before commencing charging:
Did you select the appropriate program suitable for the type of battery you
are charging?
Did you set up adequate current for charging or discharging?
Have you checked the battery voltage? Lithium battery packs can be wired
in parallel and in series, i.e. a 2 cell pack can be 3.7V (in parallel) or 7.4V (in series).
Have you checked that all connections are firm and secure?
Make sure there are no intermittent contacts at any point in the circuit.
During charge process, a specific quantity of electrical energy is fed into the
battery. The charge quantity is calculated by multiplying charge current by
charge time. The maximum permissible charge current varies depending on
the battery type or its performance, and can be found in the information by
the battery manufacturer. Only batteries that are expressly stated to be
capable of quick-charge are allowed to be charged at rates higher than the
standard charge current.
Connect the battery to the terminal of the charger: red is positive and black
is negative. Due to the difference between resistance of cable and connector, the charger can not detect resistance of the battery pack, the essential
requirement for the charger to work properly is that the charge lead should
be of adequate conductor cross-section, and high quality connectors which
are normally goldplated should be fitted to both ends.
Always refer to the manual by battery manufacturer about charging methods,recommended charging current and charging time. Especially, the
lithium battery should be charged according the charging instruction
provided by the manufacturer strictly.
Attention should be paid to the connection of lithium battery especially.
Do not attempt to disassemble the battery pack arbitrarily.
Please get highlighted that lithium battery packs can be wired in parallel
and in series. In the parallel connection, the batterys capacity is calculated
by multiplying single battery capacity by the number of cells with total
voltage stay the same. The voltages imbalance may cause fire or explosion
Lithium battery is recommended to charge in series.
Discharging
The main purpose of discharging is to clean residual capacity of the battery, or
to reduce the battery voltage to a defined level. The same attention should be
paid to the discharging process as charging. The final discharge voltage should
be set up correctly to avoid deep-discharging. Lithium battery can not be
discharged to lower than the minimum voltage, or it will cause a rapid loss of
capacity or a total failure. Generally, lithium battery doesn't need to be
discharged. Please pay attention to the minimum voltage of lithium battery to
protect the battery.
Some rechargeable batteries have a memory effect. If they are partly used and
recharged before the whole charge is accomplished, they remember this and will
only use that part of their capacity next time. This is a memory effect. It is said
that NiCd and NiMH batteries are suffering from memory effect. NiCd has more
memory effect than NiMH.

A and Channel B is identical.
1. Connection
1) Connecting to power source
There are two kinds of inputs for YUNEEC A10, DC11-20V and AC 100-240V.
A. Operating in AC mode
YUNEEC A10 comes with built in switching power supply. You can connect
the AC power cord dire ctly to the main AC socket. (100-240V AC).
NOTE: The charging power in AC mode is 200W totally for Channel A and
Channel B.
B. Operating in DC mode
Please connect YUNEEC A10 with AC/DC power supply by supplied DC input
cable. Also you could use terminal clips with DC connectors, for attaching directly to
12V car batteries. It is critically important that you use either a fully charged
13.8V car battery or a high quality AC/DC power supply in the range of 11-20V
DC output with minimum power 260W or higher to insure reliable performance.
NOTE: The charging power in DC mode is 100W for Channel A and 100W for
Channel B. Total power of A10 is 200W.
2) Connecting the battery
Important!!! Before connecting a battery it is absolutely essential to check one
last time that you have set the parameters correctly. If the settings are incorrect,
the battery may be damaged, and could even burst into flames or explode. To
avoid short circuits between the banana plugs, always connect the charge leads
to the charger first, and only then to the battery. Reverse the sequence when disconnecting the pack.
3) Balance Socket
For safety issue, the default setting for charging Lithium (LiPo, Lilo, LiFe and LiH V)
battery is using balance adaptor to connect battery and charger in Charge, Fast
Charge, Balance Charge and Storage modes. But if the battery comes no balance
wire, you could disable this function in system setting?as?following,

COMMONLY USED TERMS
Commonly used terms
Final charge voltage: the voltage at which the battery's charge limit (capacity
limit) is reached. The charge process switches from a high current to a low maintenance rate (trickle charge) at this point. From this point on 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 is
reached. The chemical composition of the batteries determines the level of this
voltage. Below this voltage the battery enters the deep discharge zone. Individual cells within the pack may become reverse polarized in this condition, and
this can cause permanent damage.
A, mA: unit of measurement relating to charge or discharge current.1000 mA =
1 A (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 2 A, it has been fed 2 Ah of
energy. It receives the same quantity of charge (2 Ah) if it is charged for 4 hours
at 0.5 A, or 15 minutes (=1/4 h) at 8 A.
'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).
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. A 8-cell
pack will have a nominal voltage of 9.6 volts (8x1.2).
-.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 (3x3.7).
-.LiIo: multiply the total number of cells in the pack by 3.6. A 2-cell LiIo wired in
series will have a nominal voltage of 7.2 volts (2x3.6).
-.LiFe: multiply the total number of cells in the pack by 3.3. A 4-cell LiIo wired in
series will have a nominal voltage of 13.2 volts (4x3.3).
-.LiHV: multiply the total number of cells in the pack by 3.7V. A 4-cell LiHV wired
in series will have a nominal voltage of 14.8 volts (4x3.7).
If the nominal voltage of the battery is not printed on the battery's label, consult
your battery manufacturer or supplier. Do not guess the rated voltage of battery.
