LIFECYCLES (BATTERY LIFESPAN)

Up to 80% capacity for 5,000 cycles under recommended conditions—compared to just 500 cycles for typical SLA batteries. Pro Guide Lithium batteries deliver exceptional longevity, reducing the cost per use to a fraction of traditional batteries.

OPERATING TEMPERATURE

Built for tough and extreme environments, Pro Guide Lithium batteries surpass SLA and other lithium options. With optimal operating temperatures from -20°F to +140°F (reliable performance down to -20°F), these batteries are designed to excel in harsh conditions. Note: avoid charging below 32°F for optimal results.

DISCHARGE

150A max continuous discharge. The flat discharge voltage curve provides a 75% bigger capacity then a SLA 50Ah battery.

CHARGE

50A 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.
