OPTIMISING YOUR CHARGING
Embedded within every iTechworld X Range battery lies a sophisticated battery
management system (BMS) which sets our batteries apart from conventional
lead-acid, calcium, or even other lithium batteries. This BMS enables the battery to
accept a broad range of charge proles, including sealed, ooded, AGM, and GEL,
making it versatile for various charging systems. However, it's important to note that
the battery is not compatible with calcium-based charging proles.
For optimal performance in systems with adjustable parameters, we recommend
following our guidelines below. However, if your charger offers a dedicated lithium
charge prole, it's advisable to use that prole for the best results.
BULK: 14.4v
ABS: 14.4v
FLOAT: 13.5V
RECOMMENDED CHARGING CURRENT
iTECH400X PRO: 1-150A
iTECH240X PRO: 1-100A
iTECH120X PRO: 1-60A
iTECH120X: 1-50A
iTECH100SX: 1-50A
SAFE MODE
We are committed to delivering the safest batteries in the Australian market, which
is why we've integrated multiple safety features, including over-current protection,
over-voltage protection, high and low-temperature protection, cross polarity
protection, and over-discharge protection.
In the event that any of these safety features are activated, the iTechworld lithium
battery will drop into safe mode, rendering it temporarily unusable until it is brought
out of safemode. In nearly all situations, except for when the battery's voltage falls
below 10.5 volts, the battery is designed to automatically exit safe mode.
For example, if the battery's internal temperature surpasses 80 degrees, it will enter
safe mode. However, as soon as the internal temperature drops below 80 degrees,
the battery will automatically recover and exit safe mode.

Please follow one of the below procedures to bring your iTechworld lithium
battery out of safe mode.
If you have a solar panel in ideal weather, please follow the below steps in
sequence to bring your iTechworld lithium battery out of safe mode.
• Disconnect all loads/inputs from the iTechworld battery.
• Connect your ‘at’ battery to an unregulated solar panel.
• Leave the battery connected to the panel for 5 minutes.
• Once that 5 minutes is up. Disconnect the battery from the panel.
• Reconnect the battery to another charging source as soon as possible.
(DCDC charger, Regulated solar panel, AC charger, etc)
If you have a portable Jump Starter, follow the below steps in sequence to bring
your iTechworld lithium battery out of safe mode.
• Disconnect all loads/inputs from the iTechworld battery.
• Connect the Jump Starter cables to the battery (Positive to Positive,
Negative to Negative)
• Connect an ACDC charger to the iTechworld battery. We recommend a three
stage 20 amp or higher charger.
• Activate the jump starter to supply power to the iTechworld battery. The
charger will now detect the battery and begin to charge.
• When the charger begins to charge the iTechworld battery, disconnect the
Jump Starter from the battery.
• The charger should continue to charge the iTechworld battery, bringing it
out of safe mode.
If you have a charged battery (E.G. car battery) and jumper cables, follow the below
steps in sequence to bring your iTechworld lithium battery out of safe mode.
• Disconnect all loads/inputs from the iTechworld battery.
• Connect your ‘at’ battery to an unregulated solar panel.
• Disconnect all loads/inputs from the iTechworld battery.
• Connect the iTechworld battery in parallel to a different battery (number 2)
• Connect an ACDC charger to the iTechworld battery at the same time as the
paralleled battery and allow it to begin charging. We recommend a three
stage 20 amp or higher charger.
10
• When the charger begins to charge the iTechworld battery, disconnect
battery number 2.
• The charger should continue to charge the iTechworld battery, bringing it
out of safe mode.
• Allow the charger to fully charge the battery.
STORAGE
When your iTechworld X range battery is not in use, it is recommended to
completely isolate the battery, charge it up to 13.5V and check the voltage every 3
months, then charging the battery as needed. To ensure your battery is completely
isolated, it's essential to disconnect it from any connected devices or systems.
You can also keep our maintenance chargers connected permanently, but if the
battery is going to be completely out of use, keeping it connected is not necessary.
INSTALLATION
Your iTechworld X Range battery boasts an impressive IP67 rating, making it suitable
for installation in a wide range of environments. Here's what you need to know:
The X Range battery can be installed in any orientation, except for upside down
(with terminals facing down). For those looking to mount your X Range battery
under the bonnet of a vehicle, we recommend using a heat shield to protect the
battery from under-the-bonnet temperatures. With the robust IP67 rating and
these installation guidelines, your iTechworld X Range battery is ready to deliver
reliable power wherever you need it.
