SP-24V10-EP Data Sheet STARKPOWER "Deep Cycle" ENERGY STORAGE BATTERY: StarkPower’s “Deep Cycle” Lithium Iron Phosphate (LiFePO4) battery is the ultimate in weight versus power technology. This is a drop in replacement for your Lead-acid battery, and will require no change to your existing system. It can be placed in scooters, wheelchairs, UPS Backups, photography or anything that uses a sealed lead acid battery. FEATURES: • Ultra light. One fifth the weight of lead-acid batteries on average • Twice to four times the service life of lead-acid batteries • Drop-in replacement for your OEM battery • Fast recharge rate • No explosive gasses during charge, no lead, no acid • Environmentally friendly SAFETY: • Internal over charge protection. • Internal low voltage protection. • Internal short circuit protection. • Internal cell balancing. • Auto Restart function. • No presence of toxic substances. LIFETIME: • Expected number of charge cycles over 2,000. • Self-discharge rate only 2% per month. • Expect 8-10 years of battery life that will reduce your operating cost by half compared to lead acid.

SP-24V10-EP Data Sheet CHARGING: The "Deep Cycle" energy storage battery is intended to be used as a direct replacement for lead acid batteries used in energy storage systems. It is best for the "Deep Cycle" battery not to be trickle charged but to use advance chargers that turns OFF charging current when the battery is completely charged at 29.2V. StarkPower sells "Smart" chargers for lithium batteries. Using lead acid chargers that charges up to 32V, along with leaving them ON, will damage the Lithium battery over extended time. Dimensions equal to the standard battery for direct replace. LiFePO4 contains no poisonous lead, no acid, and does not create gasses during charge, as traditional Lead-Acid batteries do. Compared to lead-acid, Lithium Iron Phosphate batteries are also extremely light, have much lower self-discharge, do not sulfate, and are environmentally friendly. StarkPower “Deep Cycle” Models have a Battery Management System (BMS). BMS monitors the key operational parameters during charging and discharging such as voltages, currents and internal temperatures.
