Frequently Asked Questions

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.

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.

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.

If you have close to zero volts in both on and off state, your internal protection circuit has tripped. Please get in touch with Discover here.

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

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 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.

Battery charge may be low. Charge your battery fully before applying the load.

If this is a new installation, check to ensure your system load does not exceed your battery ratings.
