THUMPER – ULTIMATE PORTABLE DUAL BATTERY SYSTEM

Blue Apple power packs are designed and manufactured in Australia for the harsh Australian environment. The Thumper range is designed to take the place of, or even work alongside of a dual battery system in the vehicle.

Your Thumper unit is designed to offer 12 volt power for the running of portable refrigerators and other 12 volt accessories.
Your Thumper is also designed for jump starting via the Heavy duty 175Amp Anderson connector; completely ‘spike protected’ when jump starting, the Thumper ensures protection of the vehicles computer chips, in built GPS systems etc.

Your Thumper unit consists of multiple 12 volt AGM (Absorbed Glass Matt) cells, linked in parallel. These cells are maintenance free and will not leak or gas when charging; perfect for use inside the vehicle or enclosed areas.
Your Thumper does not hold a ‘memory’, which means that at any stage, regardless of the state of charge, your Thumper may be recharged or discharged, without damage occurring to the life of the battery.

Your Blue Apple Thumper unit is completely recharge before purchase. The condition of the cells can be checked by pressing the push button on the front of the unit illuminate the blue LCD display gauge. Cross-reference the gauge against the voltage available. This gauge is extremely low draw and can be left on if require to monitor the Thumper’s condition. If left illuminated the gauge will draw approx 1 Amp over a 14day period.

Your Thumper will operate at any angle, in temperatures ranging from -25C - +75C.
The unit is internally marinised to aid in the protection against salty air and high humidity; perfect for the marine industry.

The outlets on the front of your Thumper are marine grade and are protected via a 15Amp circuit breaker. If the circuit breaker trips, simply push it backing to reset.

All connections on the Thumper may be used for recharging or discharging.

Jump leads are provided and may be used as required by connecting to the 175Amp Anderson connector located on the side of the unit. Disconnect jump leads after use.

Your Thumper is provided with a 50Amp Vehicle Charging System, which remains the best method of recharge. The charging kit is designed to be hard mounted into the vehicle, if installed correctly; this kit will provide a charge rate of up to 50Amps.
Depending on the unit’s requirements and the vehicle’s alternator, the charge kit has the ability to recharge the unit within 2-4 hours of driving.
Your Blue Apple Thumper can be continuously connected to the vehicle charging kit without risk whilst simultaneously providing power for on-board accessories (for example – car fridge) if desired.

Your Thumper can charged from 240 Volt; however, the charger MUST be regulated or automatic to ensure that the cells are not damaged if accidently left for extended periods. Simply connect the alligator clamps of your regulated or automatic charger to the Thumper via the 175Amp Anderson connector (positive to the positive terminal and negative to the negative terminal)

Chargers should not exceed 14.8 volts as this will result in damage to the cells and will void the warranty of your Thumper unit.
• A 240 Volt – 12 Volt power supply to run your fridge is not a suitable device for charging.

Blue Apple power packs are considered flat at a voltage of 10.5 Volts.
When recharging via 240 Volt, the charger should have the ability to fully recharge the unit within 25 – 30 hours. Longer periods of charging will not result in better performance and may result in damage to the cells, which will affect your warranty.

For an accurate reading of your Thumper’s state of charge, wait for 30 minutes after disconnecting from the charger as will allow time for any “surface charge” to fade.

Your Thumper is compatible to recharge from solar panels, providing they are “ regulated”. Remember that the solar panels are capable of producing 19 – 21 Volts and will damage the cells of the Thumper if directly connected to the unit without the use of a solar regulator. The panel may be connected to any outlet of the Thumper in order to recharge.
** Please feel free to contact BLUE APPLE for further information about solar.
Home of 12 Volt now offers a range of fixed mount and portable solar panels.

Although your Thumper unit is 12 Volt, it is compatible with the use of inverters. Inverters convert 12volt DC to 240 Volt AC for the running of 240volt appliances when away from power.

Home of 12 Volt stock the complete range of Blue Apple inverters – please contact us for further information. ( 08 8262 6890 – 8391 3121)

Overloading inverters will cause damage and will void warranty. Never attempt to use an inverter beyond maximum output capacity, E.G a 300 watt inverter has a maximum load of 300 watts ONLY. * Check the rating of all appliances before using on your inverter.

The inverter may be operated when charging unit from 12 volt (vehicle charging); however, it is recommended to not exceed a 500 watt draw when doing so.

Do not operate the Inverter when charging from 240 Volts as the increased voltage may result in damage to the inverter.

Any Inverter 150 watts or less may be connected via the Thumper’s Cigarette/Hella outlet. (If a 300watt Inverter is connected to the Cig/Hella outlet then it is recommended to only utilise up to 150watt draw as an increase draw may result in damage to the outlet).

Inverters exceeding 300 watts should be connected via the 50Amp or 175Amp Anderson connection. * Please feel free to Contact Home of 12 Volt for more information regarding the connections and use of inverters with the Thumper.

The Inverter will use power from the Thumper unit if left turned on even if an appliance is not in use. The draw is approx 0.5 Amp per every hour left on. It is considered good practice to always switch the inverter off when not in use to ensure both safety and minimise power consumption.

The Inverter may have a warm up time delay of approx 3 – 5 seconds when starting up. Always switch the Inverter on first then the appliance.

Care and Maintenance
The Thumper is basically maintenance free. However, there are things that can be done to help prolong the life of your Thumper.

If the unit is not continuously charged through the (which is the best method of prolonging the life expectancy (, then it is recommended to:

• Always store the Thumper in a fully charged condition (12.7Volts or above)
• Never store the Thumper directly on a concrete floor for prolonged peroiods

Trouble Shooting
Thumper fails to operate at front sockets – no 12 volt output
• Be Sure to check the unit is in a charged condition
• Check if the circuit breaker has tripped, simply push to reset
• Contact Home of 12 Volt if the above does not resolve the problem

Thumper fails to operate through jump leads
• Check the unit is in a charged condition
• Check that output terminals are clean and that battery terminals are clean
(make sure terminals are making good contact)
• Be sure that battery in car is fitted, even though battery is flat. Units are designed to download to an existing battery.

Thumper fails to recharge from a 240 Volt charger
• Use only fully regulated or automatic chargers on all Thumper units. (Refer to section Charging from a 240 Volt source). Many 240 Volt chargers are voltage activated and if the Thumper’s voltage is less than 8-9Volts then the charger may not switch on. Charging is then only possible via the vehicle charging system.

Thumper performance decreases with each use
• The Thumper is not fully charged for subsequent use (Refer to Charging Methods)
• If problems persists contact Blue Apple (08 8391 3121)
• Possible repack of cells may be required (2 year warranty is renewed)
