ECO WORTHY 12V 30AH LiFePO4 Battery, Rechargeable Lithium Ion Phosphate 4000+ Deep Cycle Battery for Trolling Motor, Golf Gart, Kids Scooters, Power Wheelchairs

Long service life: Lead-acid batteries usually only last for 300-400 cycles, while our lithium-iron batteries can continue for more than 4000 cycles and maintain 80% capacity after 3000 deep cycles. The service life is more than 8 times that of lead-acid batteries Small size and light weight: The 30Ah lithium battery weighs only 7.05 pounds, which is only 1/3 of the weight of a lead-acid battery, easy to move and install. It is an ideal choice for outdoor camping power supply and simple indoor installation BMS Comprehensive Protection: The lithium battery has a built-in Battery Management System (BMS) that can protect it from overcharging, deep discharge, overload, overheating and short circuit, and low self-discharge rate Capacity Expansion: The batteries support series and parallel connections for larger capacity and higher voltage. For instance, to build a 48V battery bank, you can arrange 4 identical batteries in a 2P4S configuration (two parallel groups connected in series), which is within the recommended limit of no more than 4 units per parallel string Suggestions: Recommended with ECO-WORTHY 12V 5A or 10A Automatic Smart Battery Charger. When LiFePO4 battery is completely protected by BMS, ECO-WORTHY battery charger can activate the battery, charge the battery normally, and restore the battery to normal voltage state
