LIFECYCLES (BATTERY LIFESPAN)
Up to 80% capacity for 5,000 cycles under recommended conditions—compared to just 500 cycles for typical SLA batteries. Millertech Lithium batteries offer exceptional longevity, making the cost per use only a fraction of that of traditional batteries.
OPERATING TEMPERATURE
Engineered for rugged and extreme conditions, Millertech Lithium batteries outlast SLA and other lithium options. With an optimal operating range from -20°F to +140°F (performing reliably down to -20°F), these batteries are built to handle tough environments. Note: For best results, avoid charging below 32°F.
DISCHARGE
275A max continuous discharge. The flat discharge voltage curve provides a 75% bigger capacity then a SLA 50Ah battery.
CHARGE
100a max, 14.4V recommended, 15V max Please note: this battery should be charged using a LiFePO4 compatible charger. A SLA charger may work, but will reduce performance and lifespan of the battery.
INCLUDES ACTIVE BMS PROTECTION
Equipped with an advanced circuit, this battery ensures cell balancing, low and high voltage cutoff, short circuit protection, and high-temperature protection. These features boost performance and significantly extend the battery's lifespan.
