Store in a fireproof container and away from children. Capacity For a longer-lasting product, it is best to store your battery at a 50% charge level and recharge every three months if it is not going to be used for a long time. Tightly screw in the post bolts. Having loose battery terminals will cause the terminals to build up heat resulting in damage to the battery. This battery is not intended to be used to start any devices,please DO NOT use it as a starting battery. Suggestions for Long-term Storage: Please take care to avoid metal or conductive objects touching the positive and negative terminals of the battery at the same time during your operation, otherwise it is likely to cause a short circuit. DO NOT install the battery sideways or with the top down. If ou are not sure about the installation direction,please contact to confirm the direction. THINGS TO KNOW BEFORE USING THINGS TO KNOW BEFORE USING Recharge Every 3 Months 10°C~35°C Based on the characteristics of Lithium Iron Phosphate (LiFePO4) batteries, the voltage measured by all LiFePO4 batteries during charging/discharging is not the real voltage of the battery. Therefore, after charging/discharging and disconnecting the battery from the power source, the voltage of the battery will gradually drop/increase to its real voltage. If you need to test the real voltage of the battery, please disconnect all the connections to the battery and test its voltage after putting it aside for over 30 mins. CHARGING METHODS CHARGING METHODS THE VOLTAGE WHEN CHARGING & DISCHARGING Put the red probe (+) tightly on the tightly screwed positive post bolt, and the black probe (-) on the tightly screwed negative post bolt. Do not touch the metal part of the probes with your hands during use. Tips When Testing The Battery Voltage by A Multimeter 51.2v CC (Constant Current) Phase(T1) In the beginning, a discharged battery will be charged with a constant current and voltage will be climbing steadily until reaching the constant voltage setpoint which varies for different charging methods. The material characteristics of the LiFePO4 battery determine that its charging curve is obviously different from that of a lead-acid battery. Compared with a lead-acid battery, the LiFePO4 battery has a simpler charging process and mode. Therefore, it is recommended to select LiFePO4 for your charging mode. If LiFePO4 mode is not available, please refer to the recommended parameters on Page 07~08 for setting. CHARGING METHODS CV(Constant Voltage) Phase(T2) The battery maintains a constant voltage during this phase while the current gradually decreases to 2A (0.02C)which is also known as tail current . At this point, the charging is cut off and the battery is fully charged. Tail Current(A)= Battery Capacity*0.02C.E.g.,100Ah*0.02C= 2A tail current. BATTERY CHARGING LOGIC LiFePO4 Battery Charging Curve LiFePO4 Battery Charging Mode Absorption Phase(T2) The battery reaches the absorption voltage setpoint and holds the voltage constant while the current gradually decreases until the battery is becoming full (within10-20%). Generally, absorption will not exceed 3 hours to prevent overcharging. (This phase is basically equivalent to the CV phase of LiFePO4 battery charging.) Bulk/ Boost Phase(T1) In the beginning, a discharged battery will be charged with maximum current and voltage will be climbing steadily until reaching the absorption voltage setpoint. (This phase is basically equivalent to the CC phase of LiFePO4 battery c…
