Thank you for purchasing the TURNIGY Accucell-8150. This is a
rapid charge/discharger with built in balancer, computerised with
microprocessor and specialised operating software. Please read
this entire operating manual completely and attentively before using.

Features

Optimised operating software

When charging or discharging, It has an ‘AUTO’ function that sets the
feeding current automatically. Especially for Lithium batteries, it can prevent
the over-charging can lead to an explosion by users fault. Every program in
the unit is controlled with mutual links and communication for every possible
error so it introduces a maximum safety. These can be set at users option.
Special recharge plugsport for receiver,transmitter and igniter charger. And
for frequently used charger port such as multi purpose crocodile pin etc.
It provides most convenient balance charge port for Lithium batteries, with
separated 3,4,5,6,7,8 charge port, and external reverse connector.

High-power and high-performance circuit

It employs the circuit that has maximum output power of 150W. As a result
it can charge or discharge up to 27cells of NiCd/NiMH and 8 series of Lithium
batteries with maximum current of 7.0A. Furthermore the cooling system is
so efficient that can hold such a power without any trouble of running the
CPU or the operating program.

Individual voltage balancer for Lithium batteries inside

It has an individual-cell-voltage balancer inside.This does not require any
extra balancer separately when charging Lithium batteries(Lilo/LiPO/LiFe)
for cell voltage balancing.

Balance individual cells on discharge

It also can monitor and balance individual cells of the Lithium battery pack
during the discharge process. If the voltage of any one cell varies abnormally,
the process will be stopped with the error message.

Accept various types of Lithium battery

It can accept three types of Lithium batterles- Lilo, LiPo and LiFe. They have
different characteristics by their chemistry. You can select any one of them
that you are going to process before the job. For their specifications,
refer‘Warnings and safety notes’section.

Lithium battery ‘Fast’and ‘Storage’mode

You can charge Lithium battery for special purposes. ‘Fast’charge reduces
the charging time of Lithium battery and ‘Storage’mode controls the final
voltage of the battery to be suit for long time storage.

Maximum safety

Delta-peak sensitivity: The automatic charge termination program works on
the principle of the Delta-peak voltage detection.(NiCd/NiMH)

Auto-charge current limit: When charging NiCd or NiMH at ‘AUTO’current
mode, you can set the upper limit of change current to avoid from high
current charging. This is very useful when charging the low impedance and
small capacity NiMH battery in “AUTO’mode.
Capacity limit: The changing capacity always calculated by multiple of the
charging current and time. If the charging capacity exceeds the limit the
process will be terminated automatically when you set the maximum value.
Temperature limit(*): The temperature of the battery on charging will rise by
its internal chemical reaction. If you set the limit of temperature the process
will be expired forcibly when the limit has reached.
Processing time limit: you can also restrain the maximum process time to
prevent from any possible defect.
Input power monitor: To protect the car battery using as input power from
being damaged the voltage of it always monitored. If it dorps below the lower
limit the process will be ended automatically.
Automatic cooling fan: The electric cooling fan comes into action automati­cally only when the internal temperature of the unit is raised.

Data store/load

For users convenience it can store maximum 10 data of different batteries.
You can establish the data contains program setting of the battery to charge
or discharge continually. These data can be called out at any time you need
and the process can be executed without program setting.

Cyclic charging/discharging

Perform1 to 5 cycles of charge>discharge or discharge>charge continually
for battery refreshing and balancing.

PC based analysis using USB communication(**)

For technical expert, A8 offers PC based program can analyse the charac­teristic of the battery by USB port. It shows a graph of voltage, current,
capacity and temperature curves. It also shows the individual voltage of each
cell in the Lithium battery pack.

Multi-use wires

We provide you with 7 kinds of wires for you to choose, so you can charge
and discharge your battries more conveniently.

Warnings and safety notes

�Never leave the charge unsupervised when it is connected to its power
supply. If any malfunction is observed immediately terminate the process and
refer to the operation manual.
�Keep away the unit from dust, damp, rain, heat direct sunshine and
vibration. Do not dorp it.
�The circuit of the unit is designed to be powered by a 10-18V DC only.
�This unit and the battery to charge or discharge should be set up on a
head-resistant, non-inflammable and non-conductive surface. Never place
them on a car seat, carpet or similar. Keep all the inflammable volatile
materials well away from operating area.
�Be sure to understand the information of the battery to be charged or
discharged accurately. If the program is set up incorrectly the battery can
severely be damaged. Especially Lithium battery can cause a fire or an
explosion by over-charging.

Do not connect more than one battery pack to the charge lead at any one time.
Do not attempt to charge or discharge the following types of battery.

Battery pack, which consists of different types of cell (including different
manufacturers).

-Battery, which is already fully charged or just slightly discharged.

-Non-rechargeable batteries(Explosion hazard).

-Batteries that require a different charge technique from NiCd, NiMH, Lilo,
LiPo, LiFe or Pb.

-Faulty or damaged battery.

-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 of checking the following point before charge operation.

-Did you select the appropriate program, which are suitable for the type of
battery?

-Did you set up adequate current for charging or discharging?

-Lithium battery pack can be composed with parallel and series circuits
mixed. You have to check the composition of the battery pack carefully
before charging.

-Are all connections firm and safe, or is there an intermittent contact at any
point in the circuit?

Charging

A specific quantity of electrical energy is fed into the battery during charge

process. The charge quantity is calculated by multiplying charge current by
charge time. The maximum permissible charge current varies according to
the battery type or its performance, and can be found in the information
provided by the battery manufacturer. It is only allowed to charge batteries
at rates higher than the standard charge current if they are expressly stated
to be capable of quick-charge.

-Connect the battery to charge to output terminal of the charger using
suitable charge lead. They are red, positive(+)and black, negative(-).Since
the charger cannot detect the difference between the internal resistance of
the battery pack, cable resistance and connector transfer resistance, the
first requirement if the charger to work properly is that the charge lead
should be of adequate conductor cross-section. And also high-quality
connectors (normally gold-contact type) must be fitted to both ends.

-Refer to the information provided by the battery manufacturer regarding
charging methods, and verify the recommended charge current and charge
time.Especially for Lithium batteries, you have to follow the charge instruc­tion provided by the manufacturer strictly.

-Do not attempt to disassemble the battery pack arbitrarily.

-You have to pay attention to verify the capacity and the voltage of the
Lithium battery pack. It may be composed of parallel and series connection
mixed. In parallel link the capacity of the battery pack is multiplied by the
number of cells but the voltage remains same. That kind of voltage
imbalance causes a fire or explosion during charge process. We recommend
you compose the Lithium battery pack in series only.

Discharge

The typical purpose of discharge is to determine the residual capacity of the
battery, or to lower the voltage of battery to a defined level. When you
discharge the battery you also have to pay attention on the process same as
charging. To avoid the battery becoming deep-discharged, set the final
discharge voltage correctly. Lithium batteries should not be deep-discharged
to lower than the minimum voltage, as this leads to a rapid loss of capacity or
a total failure. Generally, you do not need to discharge Lithium battery
voluntarily.

-Some rechargeable batteries are said to have a memory effect. If they are
partly used and recharged before the whole charge is drawn out,
they‘remember’ this and next time will only use that part of their capacity. This
is a ‘memory effect’. NiCd and NiMH batteries are said to suffer from memory
effect. They prefer complete cycles; fully charge then use until empty, do not
recharge before storage-allow them to self-discharge during storage. NiMH
batteries have less memory effect than NiCd.

-The Lithium battery prefers a partial rather than a full discharge. Frequent
full discharges should be avoided if possible. Instead, charge the battery
more often or use a larger battery.

-The brand-new NiCd battery pack is partially useful with its capacity until it
has beeen subjected to 10 or more charge cycles in any case. The cyclic
process of charge and discharge will lead to optimise the capacity of battery
pack.

Those warnings and safety notes are particularly important.
Please follow the instructions for a maximum safety; other­wise the charger and the battery can be damaged violently.
And also it can cause a fire to injure a human body or to lose
the property.
