Please follow and understand these instructions before using the
iTechworld battery; failure to do so can cause the battery to fail.
It is strictly prohibited to disassemble the battery.
Inside the battery are electrolytes. These electrolytes can be skin
and eye irritants. Don't touch the battery directly if you see any
liquid on the battery. If there is electrolyte on your skin, please
use soap and water to wash; if there is electrolyte on your eyes,
please use lots of water to wash them and go to the hospital
immediately.
SAFETY
USER GUIDE
Do not cross the polarity of the battery.
Never plug the battery directly into 240V mains power.
Do not open the casing.
Do not throw, squeeze, puncture, strike, contort, heat, burn,
or disassemble battery.
Keep children and animals away from the battery.
Battery should be stored in a dry environment away from
water.
Battery operates best if kept above 12.8V.
When charging do not exceed 15V input. A battery charger
with cut out of 14.7V and under is required.
Do not use this battery in series or parallel with a lead acid
battery, calcium battery or other brand battery.
Exposure to sunlight can increase discharge rate of battery.
If battery shows any shape change, colour change or any
liquid seeping from battery stop using immediately and
contact iTechworld.
If the battery terminal screws are corroded, be careful not to
bend the terminals when tightening or loosening.
Do no short-circuit the battery by directly connecting the
positive and negative terminals together or with metal
conductive objects.
Do not transport the battery together with metal objects that
are conductive.
Do not leave the battery in safe mode for any longer than 7
days.

USER GUIDE
The iTechworld X range of batteries has a sophisticated Battery
Management System, Cell Balancing and the Redback Operating
System pre-installed. This hardware allows the batteries to be
charged from almost all non-lithium charging profiles. We
suggest following our guidelines below to optimise the system
for charging systems where the parameters can be changed.
If your charger has a dedicated lithium charge profile, use that
profile.
BULK: 14.4v
ABS: 14.4v
FLOAT: 13.5V
Recommended charging current:
iTECH120X: 1a - 50a
iTECH120X PRO: 1a - 50a
iTECH240X: 1a - 100a

OPTIMISING YOUR CHARGING
USER GUIDE
Please note that a lithium battery's discharge curve will differ
from your previous lead acid batteries. Please study the
discharge curve below to better understand how the lithium
battery will perform.
DISCHARGE CURVE
USER GUIDE
Inside each iTechworld battery is a Battery Management System
that has several different safety features that you will not find in
lead acid, calcium or even other lithium batteries. To ensure
iTechworld batteries are the safest batteries available in the
Australian market, we install over-current protection, over-
voltage protection, high and low-temperature protection, cross
polarity protection, and over-discharge protection. If one of the
safety features is triggered, the iTechworld lithium battery will
enter safe mode, the battery will then become unusable until it is
brought out of safe mode.
SAFE MODE
USER GUIDE
In all instances, other than discharging your battery below 10v,
the battery can bring itself back out of safe mode. For example, if
the battery's internal temperature reaches 80 degrees, the
battery enters safe mode, the battery's internal temperature
cools below 80 degrees, and the battery will bring itself out of
safe mode.
SAFE MODE
USER GUIDE
Disconnect all loads/inputs from the iTechworld battery.
Connect the iTechworld battery in parallel to a different battery
(battery number 2)
Cross-reference the voltage on each battery in parallel – they
should both now read a similar voltage.
Connect an A.C 240v charger or a DCDC charger to the
iTechworld battery and allow it to begin charging. We
recommend a three-stage charger 20 – 40 amp charger for all
our batteries over 60ah.
For batteries under 60ah, the charger’s current output rating
should be approx. half of the battery’s capacity, examples:
When the charger begins to charge the iTechworld battery,
disconnect battery number 2.
The charger will continue to charge the iTechworld battery,
bringing it out of safe mode.
Allow the charger to charge the battery fully.
Do not reintroduce a load until the battery is fully charged.
The most common reason for an iTechworld battery to go into safe
mode is from draining the battery to a voltage of 10v or less. We
recommend the iTECHBC20 and iTECHBC40 AC chargers as they
automatically bring iTechworld batteries out of safe mode. If you
do not have an iTECHBC20 or iTECHB40, follow the methods below
to bring your battery out of safe mode.
If you have a charged battery (E.G., car battery), jumper cables and
a battery charger, follow the below steps to bring your iTechworld
lithium battery out of safe mode.
50ah battery = 25amp charger
24ah battery = 12amp charger
7ah battery = 3.5amp charger
