No matter where you are!
The 4WD Caravan Camping Thumper Battery range of portable dual battery systems have been on the market since 1997 and have sold in excess of 120,000 units Australia wide. This Australian made product has evolved over the years in line with increasing customer requirements.
The past 15 years on the market have seen many changes in the Thumper Battery such as the upgrade to the use of stainless steel or aluminium fittings, internal circuit breaker protection and Marinising of the internal circuits to protect against corrosion.
Changes to the vehicle charging system have also been made to allow for an automatic disconnection of the Thumper Battery pack when starting your vehicle. The 4WD Caravan Camping Thumper Battery range is designed to take the place of, or even work alongside a dual battery system in the vehicle.
The units are supplied with a charging system for the vehicle or boat, which when installed correctly, will allow for a recharge time of 2 – 4 hours.
Each Thumper unit consists of multiple 12 Volt AGM cells (Absorbed Glass Matt) linked together in parallel. The cells are maintenance free and will not leak or gas when charging; perfect for use inside the vehicle or enclosed areas.
You will have absolute peace of mind when jump starting with your Thumper Battery as the entire range is ‘spike protected’. This means that no damage will occur to any in built computer systems.
With all that said and done, there is only one thing left to ask:

Introducing the Thumper Mini!
This limited edition unit is the smallest of the 4WD Caravan Camping Thumper Battery range. Offering 15 AH of battery storage, 1 x cigarette type outlet, digital volt meter for accurate reading and a two pin socket for charging, this unit is designed for a person with a small power draw.
Ideal for running lighting and small draw 12 Volt accessories, the Thumper Battery Mini will even have the capability of running a 40Lt compressor type fridge for an approx time of 6 – 8 hours (variables apply).
The Thumper Battery comes included with a 2 Pin to cigarette plug charge lead. The 2 pin socket in the Thumper Battery is diode protected. This simply means that the 2 Pin socket is a “one way feed”, designed to be used for charging. The diode will prevent any “back feed” of power, allowing you to charge the Thumper Battery via an existing cigarette socket in the vehicle and not permitting power to feed back to the car stereo, etc.
It must be kept in mind that when charging via 240 volt through the 2 Pin socket, many 240 Volt battery chargers must detect voltage in order to activate the charger. As the 2 pin socket is diode protected it means that no voltage will read from the socket and therefore it is not possible to charge via this outlet by 240 volt in most cases.
The 4WD Caravan Camping Thumper Battery Mini is a perfect companion to link with a larger Thumper Battery in order to increase your capacity. It may also be linked to a larger Thumper Battery in order to recharge together from the same charging source.
Please contact 4WD Caravan Camping for options to charge you Thumper Battery Mini via 240 Volt.
Frequently Asked Questions
What is a Thumper Battery?
The Thumper Battery range is designed to take the place of, or even work alongside a dual battery system in the vehicle, boat etc. They are the perfect option for those who either have no space for a traditional dual battery system or would like to have the freedom of a portable dual battery system that can be easily separated from the vehicle with a massive spike protected jumpstarting capability. Most commonly used for powering 12 volt refrigerators & lighting although the applications stretch only as far as your imagination.
What Type of Batteries are used in the Thumper Battery Range?
Each Thumper Battery unit consists of multiple 12 Volt AGM cells (Absorbed Glass Matt) linked together in parallel for the super-fast recharge time. The batteries are 100% maintenance free and will not leak or gas when charging; perfect for use inside the vehicle or enclosed areas. The AGM batteries allow for not only deep cycling but they additionally allow for the massive cranking ability. The cells like to charge at a voltage rate between 13 - 14 Volts, which means that they are fully capable of charging via the supplied vehicle charging kit. Your Thumper Battery unit is completely recharged before delivery. The condition of the cells can be checked by pressing the push button on the front of the unit to illuminate the blue LCD display gauge. Cross-reference the gauge against the voltage readings on the sticker above to determine the remaining voltage available. The gauge has an extremely low power draw and can be left on if require to monitor the Thumper Batteries condition. If left illuminated the gauge will draw approx. 1 Amp over a 14 day period.
Will they leak or spill?
No. The AGM batteries completely sealed battery’s, meaning that you will not have to worry about the cells leaking acid, fuses, gases or any nasty odours. Due to the fact the batteries are completely sealed, it allows for the batteries to be stored on any one of their side’s even upside-down while working to full efficiency!
Can I store the unit in a non-ventilated area, such as under a bed?
Yes. Considering that the batteries are completely sealed it means that the batteries do not require a ventilated area for storage. This results in the perfect battery to have stored in an out of the way area such as under a bed in a caravan or under a vehicle's seat, even in a draw in the back of 4WD!
Do the batteries hold a memory?
Unlike many batteries on the market, the Thumper Battery does not hold a "memory", which means that at any stage, regardless of the state of charge the Thumper Battery may be recharged or discharged, without affecting the life of the unit which is approximately 5-7 years after which the units can be re-packed and given a brand new 2 year warranty.
In Vehicle Charging!
All units are supplied with a Complete Charging System for the vehicle or boat, which when installed correctly, will allow for a recharge time of 2 - 3 hours and never let your vehicles starting battery go flat as it automatically separates the Thumper Battery from the starting battery when the motor is not running. Your Thumper Battery will be supplied with a 20 Amp In Vehicle Charging System. The charging kit is designed to be hard mounted into the vehicle and when installed correctly; this kit will provide a charge rate of up to 20 Amps depending on the unit's requirements and the vehicle's alternator. Your Thumper Battery 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. (We do not recommend charging the unit straight from a vehicle's cigarette socket, as the unit will never reach full charge)
Can I charge my unit and discharge it at the same time?
YES! This is the perfect way to use your Thumper Battery. All connections on the Thumper Battery may be used for recharging or discharging.
Charging from a 240v Source
Your Thumper Battery can be charged from 240 Volt; however, the charger MUST be regulated or automatic to ensure that the cells are not damaged if accidentally left for extended periods. Chargers should not exceed 14.8 volts as this will result in damage to the cells and will void the warranty of your Thumper Battery Pack. A 240volt to 12 volt power supply to run your fridge is not a suitable device for charging. Simply connect the alligator clamps of your regulated or automatic charger to the Thumper Battery via the 175Amp Anderson connector (Positive to the positive terminal, negative to the negative terminal). Blue apple power packs are considered flat at a voltage of 10.5Volts. When recharging via 240Volt, 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 Batteries state of charge, wait for 30 minutes after disconnecting from the charger as this will allow time for any “surface charge" to fade.
Can I recharge my unit straight from my generator?
YES! We recommend putting a regulated battery charger between the generator and your unit for a faster recharge and to protect you batteries from the spikes that can occur with Generators charge outputs.
Can I use Solar Panels to charge my unit?
Yes. Solar panels can be used for charging and/or maintaining the Thumper Battery packs. Keep in mind those solar panels that are rated at 10 watts or higher must be regulated when connected to any type of battery. This will prevent the solar panel from over-charging the battery and potentially causing damage. We also sell solar panels, check our other listings.
Using your Thumper Battery
Will it run my fridge?
Yes it will and many other appliances also! One of the main accessories in which people use with the Thumper Batteries are 12/240Volt compressor type fridges. As the batteries are deep cycle it allows for the running of accessories even while the battery is charging through vehicle charging, Solar or even 240 Volt! We do not recommend running gas fridges for prolonged durations due to the high power draw (approx. 12 + Amps per hour).
Can I use inverters for 240 Volt appliances?
Yes. We now offer a range of Inverters which allows the units 12 Volt power to be converted into 240 Volts for the running of 240Volt appliances. Inverters come in a variety of sizes ranging from 150 watts at 240 Volts through to 3000 watts or more. These units will allow for the running of appliances such a laptop computers, recharging phone and camera batteries to even running TV's, DVD players or even powering tools such as drills and 4 inch angle grinders!
How long will the battery last while running my appliances?
The duration of time that the Thumper Battery will last with running accessories such as a fridge largely depends on the amp draw of the appliance in question. For example: a fridge with an average draw of 1 amp per hour would run for 30 hours with a 30 amp hour unit.
What is an Amp Hour?
Amp hour is the rated capacity of the unit. If a unit holds 60 AH and you discharged the unit using a fluorescent light that draws 1 Amp per hour the unit would last for duration of 60 hours before needing recharging.
What size Thumper Battery do I need?
To work out the size you need simply multiply the average amp per hour draw of your fridge by the amount of hours you want your fridge to run for. Take into account that if you are driving a little every day your unit will be recharging i.e. 1 hour of driving you will have put 25% charge back into your Thumper Battery.
What is the life expectancy of the batteries used?
The AGM cells used in the Thumper Battery range have a life expectancy between 5 - 9 years.The life of the Thumper Battery range largely depends on the method in which the unit is charged. Over 10 years on the market has proved that the life expectancy of the units increase when the units are charged via the provided In car charging kit. When the unit is not in use (discharged regularly), the best method of maintaining the Thumper Battery is leaving the unit connected to its In Car kit. This maintains the Thumper Battery and aids in prolonging the life of the cells used in the Thumper Battery pack.
What is the warranty of the Thumper Battery?
4WD Caravan Camping offers a Blue Apple Manufacturing 2 year warranty from the date of your purchase.
What do I do when my cells in my unit die?
Although 4WD Caravan Camping offers a Blue Apple Manufacturing 2 year warranty and has a life expectancy between 5 - 9 years, we offer our customers the chance to have their unit repacked when the cells do eventually die out! Once a customer has paid for a repack we offer our customers a new 2-year manufacturer warranty on the unit from the date of repack.

Each unit is hand made from start to finish to produce the best portable dual battery system. 100% Satisfaction Guarantee
