LIFECYCLES (BATTERY LIFESPAN)
Up to 80% capacity for 6,000 cycles under recommended conditions—compared to just 500 cycles for typical SLA batteries. Eternal Lithium batteries offer exceptional longevity, making the cost per use only a fraction of that of traditional batteries.
OPERATING TEMPERATURE
Built for tough and extreme environments, Eternal Lithium batteries outperform SLA and other lithium options. With optimal operating temperatures ranging from -4°F to +140°F (capable of reliable performance down to -20°F), these batteries are designed to withstand harsh conditions. Note: avoid charging below 32°F for best results.
DISCHARGE
80a max continuous discharge. The flat discharge voltage curve provides a 75% bigger capacity then a SLA 50Ah battery.
CHARGE
Peak charge acceptance 30A max for one minute. Please note: this battery should be charged using a LiFePO4 compatible charger.
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.
