The battery then charges at constant voltage of 14.6V while tapering the charge current. Charging will end when the current has tapered to 0.05C. The battery should be charged between 0°C and 45°C, then rest for 30 minutes before discharging. Do not exceed the max charging current, voltage, or temperature limits as specified in this document. Do not reverse-polarity charge the battery. Standard Discharge Battery should be discharged at a constant current of 0.2C to 10.0V at 20±5°C, then rest for 30 minutes before charging. Storage The batteries should be stored open circuit, and protected against the possibility of a short between the terminals. The battery should be charged once every 6 months if not in use to prevent over-discharging. They batteries should be stored at room temperature, and charged to 30-50% SOC. Warnings If the battery is over-charged and over-discharged too frequently, this will affect the long-term performance and capacity of the battery. If the battery is stored for too long, reduced capacity and performance can be expected. It is important to cycle the battery at least once every 6 months and stored at the appropriate SOC to prevent deterioration to the battery. BATTERIES PARALLEL CONNECTION GUIDE General positive General negative PARALLEL CONNECTION GUIDELINES CAUTION: Severe damage to the battery, short circuiting and sparking will happen if the batteries are not connected correctly or properly maintained. We recommend assembly be completed by fully trained professionals only. Do not reverse connect the anode and cathode, as this will damage the batteries and/or any equipment connected. DO not connect the batteries in parallel AND series at the same time. Before install Ensure wires can withstand twice the capacity rating of the battery. (Ex: ELBT6-LFP has a capacity of 6Ah, so the wire must be able to withstand 12A.) Charge all batteries with 14.6V per standard charge. Ensure all batteries have the same voltage level by fully charging each battery prior to connecting in parallel. (Voltage difference <0.2V) Install Make sure the connections are tight and the connector is protected from corrosion, wear, and seismic situations. Connecting impedance <0.1mΩ DO NOT connect more than 4 batteries per circuit. Copyright © 2022 ELB. All rights reserved. https://www.ecolithiumbattery.com/ Maintenance Make sure capacity stays within 50-60% when storing the batteries. The temperature should be 0-35 °C, humidity 75-85% and fully charged every 3 months and discharged to 50-60% capacity. Once a year, the batteries should be removed from string and individually charged. The voltage difference upon reassembly should be no more than 0.2V. BATTERIES SERIES CONNECTION GUIDE General positive General negative SERIES CONNECTION GUIDELINES CAUTION: Severe damage to the battery, short circuiting and sparking will happen if the batteries are not connected correctly or properly maintained. We recommend assembly be completed by fully trained professionals only. Do not reverse connect the anode and cathode, as this will damage the batteries and/or any equipment connected. DO not connect the batteries in parallel AND series at the same time. Before install Ensure wires can withstand twice the capacity rating of the battery. (Ex: ELBT6-LFP has a capacity of 6Ah, so the wire must be able to withstand 12A.) Charge all single batteries with 14.6V per standard charge and series batteries at a voltage of 14.6 times the number of batteries in series. Ensure all batteries have the same voltage level by fully charging each battery prior to connecting in series. (Voltage difference <0.2V) Install Make sure the connections are tight and the connector is protected from corrosion, wear, and seismic situations. Connecting impedance <0.1mΩ DO NOT connect more than 4 batteries per circuit for the ELBT Series line Maintenance Make sure capacity stays within 50-60% when storing the batteries. The temperature should be 0-35 °C, humidity 75-85% and fully charged every 3 months and discharged to 50-60% capacity. Once a year, the batteries should be removed from string and individually charged. The voltage difference upon reassembly should be no more than 0.2V.. Copyright © 2022 ELB.
