Play Longer with LITHIUM BULE

DISCOVER LITHIUM BLUE BATTERIES FOR RECREATIONAL BOATS.

LITHIUM BLUE Premium Series batteries offer BMS controlled safety, long life, lightning-fast charging performance and real-time Bluetooth access to battery State of Charge, voltage, current, temperature status. LITHIUM BLUE batteries reflect Discover’s Design for Excellence philosophy, incorporating suitcase style carrying handles, terminal protection and field serviceable fuses. LITHIUM BLUE batteries are safe, easy to install and parallel for more capacity.

No. There are no special tools required to install LITHIUM BLUE. They are the same as for installing a deep-cycle lead-acid battery. If you can install a deep-cycle lead-acid battery, you can install LITHIUM BLUE.

Yes. LITHIUM BLUE is made with cobalt and nickel-free LiFePO₄ cells that are thermally safe and long-life. LITHIUM BLUE is also IP 67 rated and suitable for applications in humid and wet environments.

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 settings closest to those recommended for LITHIUM BLUE.

For charging parameters, refer to the LITHIUM BLUE Installation and Owners Manual Table 2-1 DLB ElectricalSpecifications.

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

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

Yes. You can discharge LITHIUM BLUE down to -20⁰C. However, LITHIUM BLUE must only be charged when the battery temperature is 0⁰C or higher.

A Bluetooth App displays battery 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. Search for Discover BLUE on the App Store or Google Play.

Not recommended. For the reasons stated below, it is not recommended to use an alternator as a charge source.

It is possible. Charging with an alternator is possible. However, use one of the following is REQUIRED:

Voltage regulator, battery isolator, or DC/DC converter

Note: If the alternator charge voltage or current is too high, the BMS will protect the battery by disconnecting the battery from the system. In a one-battery system, a large voltage spike may also be created, potentially damaging both the alternator and BMS.

Note: LiFePO₄ batteries are so efficient the alternator may burn itself out over extended periods of output at or close to peak current.

Yes. LITHIUM BLUE was purpose-built for the drop-in 12V, 24V, and 36V groupings of the popular BCI G24 and GC12 sized lead-acid batteries.

North America BCI Size	G24	G12
L x W x H – Inches	10.3 6.9 x 8.3	12.2 x 7.0 x 10.8
International Equivalents	D26, H6, L3	H7, L4
L x W x H – MM	262 x 175 x 210	312 x 177 x276

No. Do not use LITHIUM BLUE to start an engine, doing so will cause irreversible damage.

Additional DC Overcurrent protection is required. The Battery fuse on the LITHIUM BLUE battery is intended to only protect the electronic components of the battery’s internal BMS. 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.

This depends on several factors. Battery banks in general need to be sized to power the loads for the desired run time. Lithium batteries also need to be sized to handle the peak current generated by the loads during start-up, 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 Specifications for System Sizing in the LITHIUM BLUE Installation and Owners Manual.

There are requirements for storing any battery so as not to cause damage. Store LITHIUM BLUE at 95% SoC or greater, and within a -10°C to 30°C (-14°F to 86°F) temperature range. After storage, charge the battery to 100% SOC and then perform at least 1 full discharge and charge cycle before returning the battery to service.

Leaving a LITHIUM BLUE battery connected to a trickle load, or to power electronics will cause the battery to be discharged 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.
