Troubleshooting Guide

If you charge your "Deep Cycle" battery above 15V for 12V battery, the BMS inside the battery terminal will turn off. The cut-off voltage settings will vary slightly depending on current levels, temperature and part tolerances. To turn ON the battery again, disconnect the charging source and let the battery rest for several seconds (~30 sec) it should come on. In the event the 12V battery had voltages higher than 18V, the internal BMS is damaged and will not turn ON.

The main system cables that run to your DC distribution (loads) should be connected across the whole bank as illustrated in the diagrams in this manual. This ensures the whole battery bank is charged and discharged equally, providing optimal performance. The main system cables and the cables joining the batteries together should be of sufficient size (diameter) to handle the total system current. Ensure the terminals and connectors are making a solid connection and are tight.

Make sure that the terminals are free of plastic caps, paint, rust, dirt, or grease that can hinder the connection. Clean the terminals as required to ensure a proper connection between the wires and battery terminals.

Make sure that you are using a lithium battery charger. You can use a lead acid charger in non-sulfate mode but the battery will not charge to 100% (about 14.6 Volts)

Your Ionic battery has a protection circuit that will attempt to put the battery in "sleep mode" if you have a short circuit, over/under voltage situation, had reversed the polarity or you pulled too much current(overload). The Battery Management System(BMS) may not be able to protect the battery from damage in all circumstances. The BMS itself may be damaged in the process of protecting the cells. In this case, if the cells were protected, you will need to have the BMS replaced by Ionic. The BMS cost is usually a fraction of the total cost of the battery.

If the battery is crystalized, it will be shorted and will need to be replaced. Crystalized batteries cannot be charged or jump started.

If the battery is completely dead; it will show voltage below 4V. 

Make sure the load is not exceeding the rated continuous output current. If the electrical load exceeds the limits of the BMS, the BMS will shut down the pack. To reset, disconnect the electrical load and troubleshoot your load and make sure that the continuous current is less than the maximum continuous current for the pack. To reset the pack, attach the charger back to the battery for a few seconds. If you need a battery with additional current output, please contact us.
