2. DO NOT ATTEMPT TO CHARGE A NON-RECHARGEABLE BATTERY (PRIMARY CELLS). They may burst
and cause injury to people and damage to property.
3. Never charge a frozen battery. Never charge a damaged battery.
4. Explosion hazard! A battery being charged could emit explosive gasses. Avoid smoking or open sparks or flames
near the battery. Explosive and flammable substances such as fuel or solvents should not be kept near the
charger or the battery.
5. Danger of chemical burns! Battery acid is highly corrosive. If your skin or eyes are exposed to acid, immediately
rinse the affected part of the body with excessive water and seek medical advice.
6. DO NOT alter or disassemble the Battery Charger under any circumstances, incorrect reassembly may result in
electric shock or fire. Unauthorized disassembly, repairs or modifications will void the official warranty.

Parts of the Charger
•
No external relays needed.
•
By default, when there are multiple inputs
available, the charger chooses which input
should be active according to priority.
1. Alternator linked to starter battery
2. Unregulated solar power using built-in
Maximum Power Point Tracking (MPPT)
Solar Controller
3. DC Supply (HU6540 only)
•
HU6540 has one more input terminal for DC
voltage source i.e. ACDC power supply,
wind turbines, etc. The charger tracks and
utilizes the power capacity of the source.
In order to access the charger terminal, select the battery type and to
install the temperature compensation & ignition over-ride cables, the
top cover needs to be removed.
Loosen the two screws as indicated to release the cover.

Wire Size Recommendation
Use the recommended minimum cable cross
section area (mm2) to avoid significant voltage
drop (approx. 0.35V). Note: Radiated Emission
was tested using 1m cable.
Mounting the Charger
Connecting the Charger
1. The charger can operate in harsh environments but
it is best to locate far away from heat sources and
excessive vibrations; and close to the auxiliary
battery. It can be installed in any position, vertically
or horizontally.
2. Use the four mounting feet of the charger to attach
to a secure flat surface.
3. Drill the four fixing holes and use the screws
included in the package to fasten the unit.
4. Remove the top cover before wiring the charger.
Put the top cover back after wiring for protection
of the terminals.

Temperature sensor
Temperature Sensor Installation
Ignition Sensor Installation
Ignition sensor is another optional feature used to detect vehicle ignition
and identify that the vehicle is running. This ignition connection enables a
“low input operation” mode for compatibility with smart (variable voltage)
alternators found in modern vehicles.
HU6525 / HU6540 supports vehicles operating with
24V alternators. These vehicles usually have two
12V main batteries connected in series. The output
of HU6525 / HU6540 will charge 12V auxiliary
battery or battery bank.
An AC powered battery charger can be connected
to the auxiliary battery without disconnecting the
HU6525 / HU6540 if it is in standby mode and not
in any charging cycle.
The HULK HU6526 Monochrome LCD display
monitors the charging status of HU6525 / HU6540 .
The unit monitors voltage, current, state of charge
and any warnings related to the charging.
Temperature sensor is an optional feature used to compensate for the
auxiliary battery temperature and protect the battery from overheating.
1. Cut a desired length of cable (recommended AWG22) and crimp to
the M3 ring terminal included with the package to make the Ignition
Sensor cable.
2. Connect the ring terminal end of the Ignition cable to the “IGN” terminal
of the charger.
3. Connect the sensor end of the Ignition cable to the ignition wiring of
the vehicle.
1. Connect the ground of the Temp Sensor cable to the “GND” terminal
of the charger.
2. Connect positive of the Temp Sensor cable to the “Sensor” terminal
of the charger.
3. Connect the sensor end of the Temp Sensor cable to the negative pole
of the Auxiliary battery.
1 - Power: Single press toggles the display to
standby mode or active mode.
2 - Mode: Single press toggles the display
mode from three choices.
3 - Brightness Up: There are five levels of
backlight brightness. Default is maximum level.
Each single press will increase the brightness
by one level up to the maximum level.
4 - Brightness Down: There are five levels of
backlight brightness. Default is maximum level.
Each single press will reduce the brightness
by one level down to minimum level.
a) Active Input Source: The charger automatically chooses which
input to use depending on the current condition. Shows STBY
if not charging.
b) Input Voltage: Actual voltage level of the active input source.
c) Output Current: Actual current level that is being charged to
the auxiliary battery.
d) Output Voltage: Actual voltage level of the auxiliary battery.
e) Battery Temperature: The temperature of auxiliary battery.
f) Battery Type: The type of auxiliary battery selected
(AGM/Gel, Wet, Calcium, Li-ion).
g) Percentage of Charge: Actual level of charge of the main
and auxiliary battery shown as graphs.
1. Choose an appropriate location for mounting the monitor.
It should be visible enough to see while driving.
2. Fix the wall mount using screws or double-sided adhesive tape.
Wall mount fixture enables adjusting the monitor for better
viewing angle.
3. Attach the monitor housing to the wall mount fixture by fitting
the ball joint stick to the slot at the back of the monitor and
sliding it to lock.
4. Connect the USB Type-C end of the monitor cable to the
HU6526 USB connector slot. Gently push the cable plug into
the display mating connector until it clicks into position.
5. Connect the other end of the monitor cable to the HU6525 / HU6540
6-pin connector slot. Follow the marking on the cable plug and
mating connector for correct orientation. Gently push the cable
plug into the display mating connector until it clicks into position.
6. At this point, display icons should be visible in the screen if the
charger is powered.
7. Press the Power button to toggle the monitor from standby
mode and operating mode.
8. To disconnect Data Cable from the charger, apply little pressure
on the sides of the Data Cable plug and slowly pull it back.

Remote Display Warning Messages
Remote Display Installation
a) – Low Voltage Warning or Battery not connected. The main or Auxiliary battery voltage is lower than 11.4V
or there is no connection to one of the batteries. Fuses and connections must be checked.
b) Flashing Voltage with – Battery won't hold charge.
c) OVP – Over Voltage Protection. High voltage is detected at any of the SOLAR, ALT, AUX or DC terminals.
d) OCP – Over Current Protection. The detected charge current is higher than specifications. Check short
circuits or cable faults and then reset the whole system.
e) OTP – Over Temperature Protection. Charging is suspended to prevent damage to the battery when the
detected battery temperature is above 50ºC. Charger also stops if internal temperature is above 115ºC.
The device will resume charging once temperature drops to a safe level.
f) REV – Reverse Polarity Protection. The auxiliary battery connection is reversed. Check the connection.
g) BAD – Battery can’t be recovered. The charger has detected that the auxiliary battery is unable to be charged
safely. Inspect the battery, replace if necessary.
