Thank you for purchasing the Reactor 500 LiPo balancing charger from hpi-racing.
This product is a rapid charger with a high performance microprocessor and specialized operating
software. Please read the operating manual carefully before using this product, as it covers all
aspects of operation and safety.
Introduction

2
Fast and storage mode for lithium battery
There are two charge modes for your lithium cells. ‘Fast’ is the normal charge mode for everyday
use.‘Store’ mode allows you to preset the voltage cut off of the charge process at a low level. This is
ideal for storing your lithium cells
Adaptable to various types of lithium battery
All types of lithium cells are covered with charge options for Li-ion, LiPo and LiFe series cells
Balancing individual cells battery discharging
While discharging the Reactor 500 can monitor and balance each cell on the battery individually. If
during discharging it detects any abnormal cell voltages it will automatically stop and inform you.
Internal independent lithium battery balancer
The Reactor 500 employs an individual cell voltage balancer. This means it is not necessary to use
an external balancing system
Optimized operating software
The Reactor 500 features an AUTO detection function that sets the feeding current during charging
and discharging. This can prevent overcharging, especially for lithium cells, which may lead to
battery failure. If any malfunction is detected an alarm will sound and the charger will automatically
disconnect the charging circuit. All the programs are monitored in this way to achieve maximum
safety and minimize failure. All the internal settings can be congured by the user.
Special Features
Processing time limit
A user programmable maximum time limit can be set to aviod any possible defect.

3
Cyclic charging/discharging
Revive battery packs for periodic maintenance or after a long storage. The charger safely charges
the battery to full capacity then slowly discharges it to a safe level up to 5 times. Ideal if you don’t use
your batteries regularly.
Data store/load
Simplify charging by storing up to 10 battery pack proles for charging different types of car/plane
batteries, transmitter pack, receiver batteries and more.
Input power monitoring
If a DC power supply is being used for operating the charger, the DC voltage is constantly monitored
to make sure that it does not fall below an acceptable limit. If this limit is reached the charger will stop
any processes automatically.
Temperature threshold*
The cells internal chemical reaction while charging will cause the temperature of the cell to rise. If the
threshold is reached the charging process will be terminated.
*This function is available when connecting the temperature probe. Available as an optional part.
Capacity limit
The charging capacity is always calculated as charging current multiplied by time. If the charging
capacity exceeds your chosen limit, the charge process will be terminated automatically.
Automatic charging current limit
It is possible to manually set the maximum charging current when charging your NiCd or NiMH battery
packs. When charging low impedance and capacity NiMH packs the ‘AUTO’ charging mode is useful.
Special Features
Maximum safety
Delta-peak is a charge termination program based on voltage detection. When the battery’s voltage
exceeds the threshold, the charge process will automatically stop.

Never attempt to charge or discharge the following types of batteries:
Do not connect more than one battery pack to the charger at any one time.
To avoid a short circuit between the charge leads always connect the charge cable to the charger
rst, then connect the battery. Reverse the sequence when disconnecting.
Warning and Safety Notes

9
The Maximum charge current varies depending on the battery type or its performance,
and this information can be found in the manufacturers battery instructions.
Only batteries that expressly state they are capable of being quick charged are allowed
to be charged at higher rates than the standard charge current.
When connecting the battery pack to the charger: Red is Positive and Black is negative.
Always make sure that the connection leads are of an adequate conductive cross
section and that the connectors used are of high quality, normally gold plated. This
reduces the resistance and allows the charger to function correctly.
Charging
Has the correct program been selected for the type of battery you wish to use?
Did you set an adequate current for charging or discharging?
Have you checked the battery voltage? Lithium battery packs can be wired in parallel
and in series, 2 cell pack can be 3.7v (in parallel) or 7.4v (in series)
Have you checked that all the connections are rm and secure? Make sure there are
no intermittent contacts at any point in the circuit.
Please be aware of the following before commencing charging:
Warning and Safety Notes

10
The main purpose of discharging is to clean residual capacity, or to reduce the battery
voltage to a dened level. The same attention should be paid to the discharge process as
charging. The nal dened discharge voltage should be set up to avoid deep discharging.
Lithium cells are especially prone to this, if discharged below a minimum voltage it will
cause a rapid loss of capacity or total failure of the cell.
Some rechargeable batteries (NiCd & NiMh) have a memory effect. If they are partly used
and then recharged, they can “remember” this and will only use that part of there capacity
next time. A discharge cycle can help return the battery to it’s normal operating cycle.
It is not recommended to fully discharge and charge Lithium Battery packs. Always keep
partially charged. From new a lithium cells full capacity can be optimized by putting the
pack through 10 or more charge cycles. The cycle process of charge and discharge will
optimize the capacity of the battery pack.
Always refer to the battery manufacturers instructions for charging methods, recommended
charging currents and times.
This is especially true for Lithium batteries. Also note that Lithium cells can be wired in both
parallel and in series. Please make sure you have the correct voltage and capacity before
commencing charging.
Do not attempt to disassemble the battery pack arbitrarily.

The screen displays the nominal voltage of the Lithium battery. There
are three kinds of Lithium cell: LiFe(3.3v), Li-ion(3.6v) and LiPo(3.7v). It
is very important that you check the battery carefully and set the correct
battery type before charging.
The Reactor 500 will recognize the cell count of the lithium battery
automatically at the beginning of the charge or discharge process.
A re-check time can be set into the process to prevent an incorrect
reading, this can happen with a deeply discharged battery. Normally 10
minutes is enough for the charger to correctly perceive the cell count.
You can increase or decrease this time depending on the capacity of the
battery pack and the overall charge time. The default setting will cover
most applications.

Initial Parameter Setup (User Setup)
Temp Cut-Off
With use of the optional temperature probe you can set the
temperature cut off to ON or OFF. If you set to ON, you can set the
maximum temperature at which the charger should allow the battery
to reach during charge. Once a battery reaches this limit, the charge
process will be stopped to protect the battery.

When a charge process starts, the integrated safety timer starts to run.
If an error is detected or the delta peak circuit can not detect whether the
battery has fully charged or not, this program will prevent overcharging.
Safety Timer Calculation
When charging NiCd or NiMH batteries, divide the capacity of the pack
by the charge current, then divide the result by 11.9 Set this number as
minutes for the value in the safety timer menu. If the charger stopped at
this time about 140% of the capacity will have been fed into the battery.

This program is only suitable for the charging/discharging of Lithium(LiPo/Li-ion/LiFe) batteries with
a nominal voltage of 3.3/3.6/3.7v per cell. Different batteries have a different charge technique.
There are two methods, constant voltage and constant current. The charge current varies
depending on the battery capacity and specication. The nal voltage is very important. It should
precisely match the voltage of the battery: LiPo is 4.2v, Li-ion is 4.1v and LiFe is 3.6v. The current
and voltage of the battery should be set correctly. When you want to change the parameters, press
START/ENTER key to make your selection blink then use DEC or INC to change the value. The
START/ENTER key will then conrm and store the value.

The “BALANCE” function is for balancing the voltage of Lithium-Polymer battery cells while
charging. In balance mode, the battery needs to have the balancing lead connected to the balance
port on the right side of the charger. The power leads must also be connected to the positive and
negative terminals. Charging in this mode means the built-in processor monitors individual cell
voltage and controls the input current fed into each cell to equalise the voltage of that individual cell
with the others in the pack.
