12.8v 100ah 1.28Kwh Ecco Lithium Battery Longer Cycle Life: Offers up to 20 times longer cycle life and five times longer float/calendar life than lead acid battery, helping to minimize replacement cost and reduce total cost of ownership. Lighter Weight: About 40% of the weight of a comparable lead acid battery. A 'drop in' replacement for lead acid batteries. Higher Power: Delivers twice power of lead acid battery, even high discharge rate, while maintaining high energy capacity. Superior Safety: Lithium iron phosphate chemistry eliminates the risk of explosion or combustion due to high impact, overcharging or short circuit situation. It can parallel up to 4 units or series up to 4 units SPECIFICATIONS Nominal Voltage : 12.8V Nominal Capacity : 100Ah Nominal Energy : 1280Wh Combination Method : 4S Cycle Life : 5000 cycles @50%DOD @35 Months Self Discharge : Months Self Discharge Efficiency of Charge : 97% Standard Discharge Cut-off Voltage (V) 10.8V Recommended Charging Voltage : 14.2V Recommended Charging Current : 50A Recommended Discharging Current ; 100/150 A Weight : 12kg Size: 330 x 172 x 220 IP 65 Notes: When the battery pack is idle for a long time, please keep its power level at about 50%; When the battery pack needs long-term storage or idleness, it should be recharged every three months, and the power level is maintained at about 50%.

Please keep the battery pack in a dry and ventilated place, avoid contact with corrosive substances, and keep away from fire and heat sources. 3 Years Warranty Warranties: All inverters and batteries must be installed by a qualified electrical wireman or Master electrician with a valid registration with the Department of Labour. A valid electrical certificate of compliance (COC) must be issued once installed, specific to the installation of the backup or solar system. The installation must be compliant with SANS 10142 and ALL its parts. Any warranty claim submitted without installation photos, a valid COC and proof of a qualified wireman/master electrician installing the unit, can be rejected and will render the warranty claim null at void.
