Congratulations on your purchase of the Hitec H4 Multi-Charger. You are now the owner of a compact multi chemistry battery charger with battery management and
integral Lithium battery balancing features.
The Hitec H4 Multi-Charger features four totally independent and identical 120 watt charging circuits for a total power of 480 watts. As a result, it can simultaneously
charge or discharge up to 4 separate battery packs.
The Hitec H4 Multi-Charger can be attached to a 12 volt car battery with the included connector.
You can connect it to a 11 ~ 18 V DC power supply with an amperage rating of 35~40 amps (480~500W).

The Hitec H4 Multi Charger automatically controls the current rate during the charging or discharging process. This feature can prevent the user from overcharging
their batteries which could lead to damage or injury. If the charger detects a malfunction, the circuit automatically disconnects and an alarm will sound. The operat-
ing functions of the Hitec H4 Multi Charger are controlled through a two-way communication link in order to maintain maximum safety with minimal errors.
All of these functions and settings are easily conſgured by the user.

During the charge process, a speciſc 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 provided by the battery manufacturer. Only batteries that are expressly stated
to be capable of quick charge should be charged at rates higher than the standard charge current.
Connect the battery to the terminals of the charger. RED is positive and BLAC-is negative. In the event there is any signiſcant
resistance in the battery cable and/or connector, the charger will not be able to properly detect the resistance of the battery
pack, resulting in an error. It is essential, in order for the charger to operate properly, that the battery charge leads should be of
adequate quality for the size of the battery.
Always refer to the manual by the battery manufacturer pertaining to charging methods. Operate according to their recommended
charging current and charging time. Lithium batteries, in particular, should be charged strictly according to the manufacturer’s
instruction. Pay close attention to the connection of lithium batteries.
9CTPKPIUCPF5CHGV[+PHQTOCVKQP
Do not attempt to disassemble the battery pack.
You should note that lithium battery packs can be wired in PARALLEL and in SERIES.
In the PARALLEL conſguration, the battery’s amperage capacity is calculated by multiplying the single battery’s capacity by the
number of cells, bearing in mind that total voltage stays the same. If the voltage is imbalanced, it may cause a ſre or explosion.
In the SERIES conſguration, the battery's voltage is calculated by multiplying the single battery’s voltage by the number of cells,
bearing in mind that total amperage stays the same. If the voltage is imbalanced, it may cause a ſre or explosion.
Lithium batteries are always recommended to be charged in series.
 &+5%*#4)+0)
The main purpose of discharging a battery is to clean the residual capacity of the battery or to reduce the battery’s voltage to
a deſned level. It is critical that the same attention be paid to the discharging process as to the charging process. The ſnal
discharge voltage should be set correctly to avoid deep discharging. Lithium batteries cannot be discharged to a voltage lower
than the minimum voltage for the cell type. Doing so will result in a rapid loss of capacity and/or total failure.
Generally, lithium batteries should not be discharged and it is not recommended. If you choose to discharge your lithium
batteries, make sure to pay attention to the minimum voltage setting.
Some rechargeable batteries have a memory effect. If they are partly used and recharged before the complete charge/discharge
cycle is accomplished, they remember this and will only use that part of their capacity next time. It is generally known that NiCd
and NiMH batteries suffer from this memory effect.

The Hitec H4 Multi Charger provides a minimum discharge voltage for your battery. This function is helpful in safely discharging your Lithium chemistry batteries.
Before changing this setting, refer to the data from the battery's manufacturer. The factory set up is the ‘Default’ value which is: LiPo = 3.7v, LiIon =3.7v,
and LiFe = 3.3v. You can manually set it up by 0.01v increments.

This sets the ſnal charge/discharge current at the end of the process. In ‘Auto’ mode, the process will terminate when the charging current goes to 1/10th of its initial
value. Otherwise, the charge current will be decreased until the designated value has been reached. The end current should be less than the initial charge current.

In ‘Cycle Mode,’ the batteries' internal temperatures are increased when charged and discharged and need time to cool down. You can manually set up cool down

When you start to charge or discharge the battery, the H4’s internal clock will start counting total processing time. By having a set safety time, the function will help
