Understanding Battery State of Charge (SOC)

State of Charge is a metered reading from a Hall Effect Shunt and is a count-down meter that is most accurate on its first cycle after calibration but becomes less accurate over time. What this means is that once the batteries are fully charged the SOC reading will be more accurate but as you use the batteries thru *micro cycles and do not fully charge them the SOC will no longer be accurate. You may see a 80% SOC but the batteries might actually be at a 20% rate. Lithionics recommends performing a full charge on the batteries every 2 weeks to recalibrate the internal Hall Effect Sensor shunt. *Please see attached document: "Lithionics - Understanding SOC" for more information. *A micro cycle is considered a discharge/recharge where the batteries are used but not fully charged.

Voltage vs SOC

Lithium batteries maintain a higher voltage throughout the state of charge compared to sealed lead acid (SLA) batteries. Voltage is not a good indicator to determine the state of charge for a Lithium battery as the charge/discharge curve is not linear. The battery management system counts AMPs going in and out to determine SOC, however, as stated above a full charge cycle on the batteries must occur every 2 weeks to keep it calibrated for proper readings. With this being said there is a chart to display ROUGH assimilation between SOC and open circuit voltage. Please see the attached document: "Lithionics Voltage vs SOC" for more information as well as graphs & charts regarding voltage and state of charge.

Lithium Battery Storage Procedures

Proper storage of your Lithium batteries is very important in order to keep the battery healthy and give it the most life. Proper storage is determined by the length of storage as well as the temperature and humidity at which they will be stored. Please see the attached document: "Lithionics Storage Procedure Rev. 7" for more information. Note: Lithionics has updated the storage procedure to include storing the batteries with a constant charge if you are storing in winter conidtions.

Lithionics Battery Bluetooth App

The Lithionics batteries can be monitored via a bluetooth connection with your smart device. You will need to download the Lithionics app and connect to the battery. NOTE: You can only connect to a single battery at a time. Please see attached document: "Lithionics Battery App" for more information. If you already have the app but are having trouble connecting to your battery, please see attached document: Lithionics Bluetooth Connectivity Support".
