WEIGHT

14 lbs

SIZE

9.00" x 5.40" x 8.25"
(Equal to Group 22 Battery in dimensions)

STORAGE CAPACITY

54 ampere hours (Ah). Astro Lithium batteries provide consistent power for all 54 amp hours. Astro Lithium LiFePO4 batteries have a flat voltage curve, which means they have a steady power output as the battery discharges. The power output will not dramatically drop like similar sized SLA batteries. You get all the juice down to the last drop.

ENGINE STARTING POWER

Rated to 500 Marine Cranking Amps (MCA) of engine starting power. Suitable for marine engines under 100hp. 1/4-1/2 the weight of a normal car battery.

Bluetooth Capable

Yes

VOLTAGE

12.8V

ENERGY

691Wh

TERMINALS

M6

LIFECYCLES (BATTERY LIFESPAN)

Up to 90% capacity for 3,000 cycles in recommended conditions. The typical SLA has 500 cycles. Astro Lithium batteries last so long that the price per use is a fraction of traditional batteries.

OPERATING TEMPERATURE

Ideal for rugged & harsh environments. Much better than SLA or other lithium’s. -4'F min, +140'F max optimal operating temps (battery performs well down to -20'F). Avoid charging below 32'F.

DISCHARGE

54 A max continuous discharge, 100 A max pulse. The flat discharge voltage curve provides a 75% bigger capacity then a SLA 50Ah battery.

CHARGE

Recommend for longest life 30A or less (1C), 14.4 V recommended, 15 V max, BMS protection from over charging will cut off at 15V. 

INCLUDES ACTIVE BMS PROTECTION

Contains a circuit that handles cell balancing, low voltage cutoff, high voltage cutoff, short circuit protection and high temperature protection for increased performance and longer life.
