SAFE MODE

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, overvoltage 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.
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.
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.

• 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:

50ah battery = 25amp charger
24ah battery = 12amp charger
7ah battery = 3.5amp charger

• 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.

If you have a portable Jump Starter, follow the below steps 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 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:

50ah battery = 25amp charger
24ah battery = 12amp charger
7ah battery = 3.5amp 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 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.

If you have a portable solar panel, follow the steps below to bring your iTechworld lithium battery out of safe mode.

• Disconnect all loads/inputs from the iTechworld battery.
• Disconnect the solar controller/regulator from the solar panel.
• Connect the unregulated solar panel to the iTechworld battery.
• Leave for 5 minutes.
• Disconnect the unregulated solar panel from the iTechworld battery.
• The iTechworld battery will have voltage present, allowing for use with a charger or regulated solar panel.
• Charge the battery to 100%
• Do not reintroduce a load until the battery is fully charged.

ITECHWORLD LITHIUM BATTERY BYPASS SWITCH

The bypass switch, allows the reset mechanism to be permanently wired to your iTechworld battery and allows for remote BMS resetting, both batteries must be on the same negative ground:

1. Install the bypass switch connecting only the positive terminals of the iTechworld battery and your main starting battery, or any other battery. Both batteries must share the same negative ground, the arrow indicated on the switch must point to the iTechworld battery.
2. Once the cable is installed you can simply press and hold the button for a few seconds to reset the BMS.

If you have our DCDC charger, you can wire it according to the diagram below.

1. Install the bypass switch connecting only the positive cable of the iTechworld battery and your main starting battery or any other battery. 2. Both batteries must share the same negative ground, iTechworld DCDC chargers have an internal common ground. Once the cable is installed, you can simply press and hold the button for a few seconds to reset the BMS.

STORAGE

Long-time storage in a hot or wet environment will damage the battery. The battery should be stored in dry and ventilated environment. The ideal storage temperature is below 25. If stored this way, it will extend the battery life. If the storage temperature surpasses 40 for an extended period (more than 30 days), battery life may be shortened; if the storage temperature surpasses 55, the battery can be damaged. When the battery is stored for more than 50 days, the preferred storage voltage is 13.2V. Checking the voltage and charging when required should be done every 60-90 days.

TRANSPORTING

The iTechworld lithium battery should always be carefully handled. Don’t throw the battery and avoid squeezing it i.e do not pack heavy objects on top of the battery.
The battery is robust and designed to handle off-road bumps.
Ensure the battery is in a secure spot where it cannot be punctured. Do not store battery with flammable, explosive goods of sharp metals. Upon delivery of battery from iTechworld please inspect for openings in the casing or other damage that could have been caused in transit. Contact iTechworld immediately if the battery does not seem right after taking delivery.
