Charging with a Lithium Charger.

Recommended. To maximize performance and cycle lifetime, use a Lithium battery charger with a dedicated LiFePO₄ charging algorithm.

Charging with a Lead-Acid Charger.

It is possible. Charging with a lead-acid charger is possible only if the bulk and absorption voltages are equal to or below the bulk voltage parameters recommended for LITHIUM BLUE batteries. If the charger cannot be custom programmed, a GEL profile is typically the lead-acid setting closest to those recommended for LITHIUM BLUE.

For charging parameters, refer to the LITHIUM BLUE Installation and Owners Manual.

Table 2-1 DLB Electrical Specifications.

It is possible. However, LiFePO₄ batteries are so efficient the alternator may burn itself out over extended periods of output at or close to peak current. Therefore, the use of a voltage regulator or DC/DC converter is required. We recommended that a professional install and configure your alternator system to charge a lithium battery.

Refer to our Application Note, Installing and Charging LITHIUM BLUE with an Alternator.

Yes. LITHIUM BLUE batteries can be connected in parallel for more capacity.

Refer to the LITHIUM BLUE Installation and Owners Manual Section 6.7 Parallel Battery Installation Procedure

LITHIUM BLUE can be installed in series to create a system up to 48V, but only if a dedicated charging channel charges each battery separately. We recommend that a professional install and configure LITHIUM BLUE batteries.

Refer to our Application Note, Installing LITHIUM BLUE in series for Trolling Motors.

Additional DC overcurrent protection is required. The battery fuse on the LITHIUM BLUE battery only protects the battery’s internal BMS’s electronic components. However, to protect the system and DC battery cables, additional DC overcurrent protection and a DC disconnect switch are required.

Refer to the LITHIUM BLUE Installation and Owners Manual Section 6.4 DC Protection.

You should not charge your battery directly from an alternator without a DC converter or other form of regulator in line.

We cannot configure and set your system up for you as it is outside of what we can possibly take responsibility for. Inverter-charger configuration is the key to off-grid performance as it is the center for all sources and uses of AC and DC power. Take the time to review all the manuals for your components to gain a better understanding of what you've got, then reach out to your point of purchase to determine if they have more resources for you from your OEM.

Yes.  You can discharge LITHIUM BLUE down to -20°C. However, only charge LITHIUM BLUE when the battery temperature is 0°C or higher.

How many batteries depend on several factors. Battery banks, in general, need to be sized to power the loads for the desired runtime. Lithium batteries also need to be sized to handle the peak current generated by the loads during startup, such as an inverter and also be able to handle the maximum charge current generated by the charging device(s).

Refer to Section 2.5 Specification for System Sizing in the LITHIUM BLUE Installation and Owners Manual.

LITHIUM BLUE displays state-of-charge on your mobile device. LITHIUM BLUE batteries include a Bluetooth App that gives real-time access to the battery state-of-charge, voltage, operating, current, temperature, status, and diagnostic reports.

Damage may occur, and your warranty will be void.

You should never store a fully discharged battery. Damage to the battery will occur and your warranty will be void.

Do not store batteries below the specifications listed in your owner's manual. Damage will occur, and your warranty will be void.

These are requirements for storing any battery so as not to cause damage. Store LITHIUM BLUE at 95% SOC or higher and within a -10°C to 30°C (-14°F to 86°F) temperature range. After storage, charge the battery to 100% SOC and perform at least one full discharge and charge cycle before returning the battery to service.

Leaving a LITHIUM BLUE battery connected to a trickle load or power electronics will cause the battery to discharge during storage. Without any load, the battery will self-discharge by approximately 3% per month. Storing or leaving the battery at 0% SOC will cause irreversible damage to the battery.

Refer to LITHIUM BLUE Installation and Owners Manual Section 11.0 Storage.

Check to ensure all connections are clean and tight to avoid voltage drops due to resistance.

Ensure all cables are correctly sized for your application to avoid voltage drops due to resistance.

Ensure that you have correctly configured your charging source and that its actual output is what is expected. Instructs vary by manufacturer.

Ensure you are using the correct charger for your application (some lead chargers won't correctly charge Lithium).

If your battery is beyond its useful life age, please replace your battery.

You could be using the wrong type of charger. See recommended specifications in the owner’s manual of your specific charger.

The charger might have settings that prevent it from charging if certain thresholds have been exceeded or have not been met. We recommend using an external source to "jumpstart the battery" to bring it above the minimum threshold.

Some chargers draw energy from the already low battery before it can initiate a charge. This activity draws your battery even lower. We recommend using an external source to "jumpstart the battery" to bring it above the minimum threshold.

Check to make sure your charging source is powered.

The battery turned itself off when it reached a low voltage protection state, meaning it has reached full discharge and needs to be charged again. This is indicated by a blinking light or an alarm sound for two minutes. If you have charged your batteries or if you do not see these conditions, please get in touch with customer service for more support.

Check to make sure the battery is on by pressing the power button.

Check for a flashing LED on the power button or a buzzing alarm tone. If flashing, the battery has gone into protection mode. Check your operating parameters to make sure you are charging correctly. If you need additional support, please get in touch with Discover here.

Please visit the support page for the AES dashboard here and follow the instructions to update your firmware to the latest version and then update your clock.

This means that one of the batteries has active protection. To investigate, please troubleshoot using the AES Dashboard.

Check to make sure the battery is operating to the required specifications. I the battery charged? ( NOTE: your inverter may be acting as a load which forces the low voltage situation again. You may need to use an external charger to bring your battery up to a minimum safe charge). If the battery is not adequately charged, it will enter a low-voltage protection mode. This protection will clear once the battery operation specifications are met.

This is a result of the battery protection auto recovery. Check to make sure the battery is operating to the required specifications. Is the battery charged? Is the temperature correct? Is the load appropriately sized? Any of these conditions can lead the battery to enter a protection mode. This protection will clear once the battery operation specifications are met.
