Thank you for purchasing a
Thumper DC
battery box.
Your satisfaction is important to us, so please take the time to read and use the information enclosed
to ensure the optimum performance of your battery box for many years to come.
General Information
The Thumper battery box is hand built in Australia by Blue Apple Thumper.
Designed to allow the user to install up to a 130 AH AGM / GEL / WETCELL type battery, the Thumper DC Battery Box now
incorporates the use of a sophisticated DC charger for both vehicle and solar charge (The Projecta IDC25). The characteristics of
this charger may vary from chargers you have used in the past, therefore, we highly encourage you to read through the provided
information carefully to ensure a complete understanding of the operation of this unit.
Operating your Thumper DC Battery Box
Your Thumper DC battery box has been designed to include the most popular sockets on the market today. The box comprises of
2 x Marine grade cigarette sockets, 1 x Engel Fridge socket (unique 2 prong socket), 1 x Dual USB socket and 4 x 50 Amp Anderson
connectors.
The two 50 Amp Anderson connectors positioned on the front and rear of your box are labelled “INPUT / OUTPUT” and will allow
you to use these sockets as both inlet for charging or an outlet for running your appliances, such as a fridge or light. The two
Anderson connectors positioned on the back left hand side of the battery box are wired directly to the IDC25 charger and are
clearly labelled “Alternator input” or “Unregulated solar input”
. Please see below information for more on these sockets.
The Thumper battery box is fitted with a digital volt meter, which will allow you to monitor the level of charge of your battery
when ON. Pressing the push button located near the volt meter will illuminate the digital volt meter,
which can then be cross-read with the voltage sticker on the top of your Thumper lid.
Please note: In order to obtain an accurate reading of your voltage, please remove any load (input
charge or discharging appliances) from your Thumper before taking a voltage reading.
Use of the USB socket:
It is important to note that the LED volt meter gauge must be illuminated in order to power the USB socket.
The USB sockets will have a minor discharge from a battery, even when not in use but when turned ON. It is therefore important
to be able to switch off the use of the USB and Volt meter when your battery box is in storage. Simply press the push button to
turn these on / off.
Internal circuit breaker protection:
Your Thumper DC battery box is fitted with internal automatic reset circuit breaker protection.
The outlet sockets located on the front of your Thumper battery box are protected internally with a 30 Amp automatic reset
circuit breaker. The Anderson connectors are protected by an independent 50Amp automatic reset circuit breaker.
Using your outlet sockets:
All of the sockets within the Thumper are wired as bi-directional, allowing the user to charge or discharge from any outlet *An
exclusion to this is the USB socket, which is purely an
outlet
offering 5Volts – min of 2.5 Amp rating. In addition to this, the two 50
Amp Anderson connectors, labelled ‘Alternator input’ and ‘Unregulated solar input’, allow only for an INPUT charge – see
information below for more details on these
The Projecta IDC25 DC Battery Charger
Your Thumper DC battery box is fitted with the latest technology in DC charging; The Projecta IDC25. This particular DC charger is
designed to allow for an optimal input charge to be harnessed from the use of both newer and older model vehicles as well as
unregulated 12 volt solar panels. The Projecta IDC25 has been hardwired to the Thumper battery box with internal circuit breaker
protection and heat sync protection. The IDC25 has a number of key functions, all of which contribute to the operation and
charging of your Thumper battery pack. It is important to understand the features of this particular DC charger as sometimes such
features can be mistaken for faults.
