3 Year WarrantyHazardous MaterialsThe next generation of power storage is here! These LiFePO4 batteries weigh less than half of their Lead Acid counterparts. They may look fairly similar to lead acid batteries, but internally they’re a totally different, next generation concept. They’re actually made up of regular 32650 LiFePO4 cells, which are in mass production for many portable devices. An internal battery management system (BMS) ensures all cells are uniformly charged and discharged, as well as providing short circuit, over current, and reverse polarity protection. This provides you with a higher degree of protection than a traditional lead acid battery which is unprotected, and can discharge rapidly under short circuit conditions, causing fire and damage. The internal BMS will also limit discharge and manage cut-off voltage, to further protect the internal cells. This 12h model can provide continuous current up to 12A. Absolutely perfect for high capacity portable power, and replacement of similar capacity lead acid / AGM battery. Features:- Much lighter than Lead Acid and AGM Batteries- Robust LiFePO4 Cells- Excellent life spanSpecifications:Capacity: 12AhService Life: 10yrs+Cycle Life: 1500+ cycles (> 80% capacity retention)Cut-Off Voltage: 10V approx.Charge Type: Constant Current / Constant VoltageDischarge Current: 12AMax Continuous Current: ≤20A (≤5 sec)Internal Cells: 32650 LiFePO4 Maximum Internal Resistance:  85M?Output Terminals: M5 Bolt DownOperating Temperature: 0-45°C (60°C max discharging)Operating Humidity: RH < 85%Storage Temperature: 0-40°C (15-25°C recommended)Storage Humidity: RH < 50%


Notes on Charging

While the internal battery management system will take care of most charging, in order to maintain optimum operation and capacity, were commend using a charger which is designed for LiFePO4 charging. These chargers are developed to work in the optimum method for recharging, providing longer service life.If you’re installing them as a house battery, then a DC-DC charger between your main battery system and the house batteries is also recommended, such as the MB3683Dual Input Multi-Stage.If you’re charging from mains power, we recommend the following chargers (see page 284 for individual details)• MB3611 4-Stage Multi-Voltage• MB3613 9-Stage Multi-Voltage• MB3621 Multi-Stage ChargerIf you are installing them off grid we recommend upgrading your charge controller to MP3741.
