We took our time to find a Lithium Battery that was affordable but still have a great warranty and performance. The Solar King 100ah LiPo4 is a great battery option for a setup with a Thumper Lithium DC-DC Portable Battery Box. One obvious benefit is the physical weight of the battery, truly making the package a easy to lift portable system.
The usable amp hours of the LifePO4 100ah battery is equivalent to a 130amp AGM battery.
The Solar King Lithium battery has a 80amp maximum discharge rate, which is ideal for a battery box setup where you are likely to power a 12v fridge, lights and charging Ipads and Tablets.
The maximum charge rate of the Solar King Lithium battery is 80amps maximum, even though the suggested charge rate is 30amps. The Solar King Lithium battery will accept what it needs as the internal BMS unit will adjust the charge input. We suggest charging the battery with a 30amp Lithium compatible battery charger. The Powertech battery can be charged on a AGM setting but this will take longer to charge.

PROJECTA IDC LITHIUM DC/SOLAR BATTERY
The IDC25L DC-DC charger is purposely designed for charging auxiliary batteries.
It includes all the features needed to maintain the auxiliary battery to its optimum
condition and to prolong the battery life.
The IDC25L converts your vehicle’s 12VDC/24VDC alternator power to the voltage
level allowing your batteries to be fully charged, prolonging battery life and
reliability. With the latest synchronous switching technology, efficiency of IDC25L
exceeds 94% at typical full load condition.
DUAL INPUT OPERATION
Allows two energy sources to power the IDC25L simultaneously. Solar input takes
precedence if solar and alternator inputs are present. When solar input cannot provide
enough energy to the load, the IDC25L will draw power from solar and alternator
The IDC25L utilises sophisticated MPPT (Maximum Power Point Tracking) solar
regulator technology. MPPT maximises the power generated from the solar panels
to the auxiliary battery.
POWER SUPPLY (CONSTANT VOLTAGE OF 13.8 VOLTS)
This sets the charge in power supply mode giving a constant voltage of 13.8VDC.
This mode is best used where appliances are drawing power from the battery,
for example a fridge.
Power supply mode can also be used to reactivate a lithium iron phosphate battery
which is on internal low voltage disconnect mode. Currently, most high capacity
12V lithium iron phosphate batteries have an in-built battery management system
(BMS). When you discharge a 12V lithium iron phosphate battery to very low output
voltage, it will activate the battery’s internal low voltage disconnect protection –
the battery will be disconnected from the charger and load. However, in charge
mode, the IDC25L will only start charging if it detects the battery is connected.
To overcome this, set the IDC25L to power supply mode until the battery internal
low voltage disconnect protection is deactivated.
SUPERIOR 5 STAGE CHARGING
Using high speed microcontroller and proprietary charging algorithm, the IDC25L
delivers a sophisticated 5 stage charging process resulting in a faster and more
powerful charge, ideal for deep cycle batteries. The first two stages increase battery
life by gently starting to charge the battery at 5% and 25% of the bulk charge
respectively. The third stage, bulk (constant current), charges the battery much faster
while the fourth stage, absorption (constant voltage), ensures the battery is thoroughly
charged. The final stage, float, maintains the battery at a safe voltage allowing it to
be maintained and ready for use indefinitely.
The ignition connection activates the lower input voltage operation to suit vehicles
with smart (variable voltage) alternators.
The IDC25L is supplied with a 2 metre temperature sensor. The sensor monitors
the battery temperature and adjusts (compensates) the charger’s output to
prevent overcharging. This is ideal for batteries used in warmer/cooler climates or
REMOTE CHARGER STATUS INDICATION
A pink wire is provided for driving an external panel mount LED indicator (Eg Narva
P/No. 62090BL) to show the status of the charger. It shows whether the auxiliary
battery is on charge (Solid Colour) or the charger is in a fault condition (Flashing).
The IDC25L will not start charging the battery (no output) unless the load is securely
connected. It prevents the output leads from sparking due to accidental short circuit
making the charger safer to use around batteries.
Reverse Connection Protection
Reverse connection on input and output terminals does not damage IDC25L internal
circuit. The IDC25L detects reverse connection condition and indicates whether input
or output connection is reversed.
Over and Under Voltage Protection
The charger will automatically shut down if there is an over voltage or under
Over Temperature Protection
The charger will lower its output current if the temperature of the unit begins
