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, over-voltage, high and low temperature, cross polarity, and over-discharge protections. If any of these safety features are activated, the iTechworld battery will drop into safe mode, rendering it temporarily unusable until it is brought out of safe mode.
- In nearly all situations, except for when the battery’s voltage falls below 10V, the battery is designed to automatically exit safe mode. For example, if the battery’s internal temperature surpasses 80°C, it will enter safe mode. However, as soon as the internal temperature drops below 80°C, the battery will automatically recover and exit safe mode.
Please follow one of the procedures below to bring your iTechworld lithium battery out of safe mode. If you have a solar panel in ideal weather, please follow the steps below in sequence to bring your battery out of safe mode:
- Disconnect all loads/inputs from the battery.
- Connect your ‘flat’ battery to an unregulated solar panel.
- Leave the battery connected to the panel for 5 minutes.
- Once the 5 minutes are 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, er etc.)
- The charger should continue to charge the battery, bringing it out of safe mode.
If you have a portable jump starter, follow the steps below in sequence to bring your battery out of safe mode:
- Disconnect all loads/inputs from the battery.
- Connect the jump starter cables to the battery (positive to positive, negative to negative).
- Connect an ACDC charger to the battery. We recommend a three-stage 20A or higher charger.
- Activate the jump starter to supply power to the battery. The charger will now detect the battery and begin to charge.
- When the charger begins to charge the battery, disconnect the jump starter from the battery.
- The charger should continue to charge the battery, bringing it out of safe mode.
If you have a charged battery (e.g., a car battery) and jumper cables, follow the steps below in sequence to bring your battery out of safe mode:
- Disconnect all loads/inputs from the battery.
- Leave the battery connected to the panel for 5 minutes.
- Once the 5 minutes are 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).
- The charger should continue to charge the battery, bringing it out of safe mode.
CHARGING
Embedded within every iTechworld battery lies a sophisticated Battery Management System (BMS) that sets our batteries apart from conventional lead-acid, calcium, or even other lithium batteries.
Including lead acid, gel, and AGM, making it versatile for various charging systems. However, it’s important to note that the battery is not compatible with calciu.m
For optimal performance in systems with adjustable parameters, we recommend following the guidelines below. However, if your charger offers a dedicated lithium charging profile, it’s advisable to use that profile for the best results.
| Charge Stage | Charge Voltage |
| BULK | 14.4V |
| ABS | 14.4V |
| FLOAT | 13.5V |
