CONNECTING THE BATTERIES IN PARALLEL

Please make sure all batteries that are connected meet the following criteria:
• Batteries have the same capacity (Ah) and are the same type (LiFePO4).
• As the built-in battery management system (BMS) may vary between brands, we advise you to choose batteries from the same brand for connection.
For optimal performance, we kindly advise you to follow the requirements listed below:
• Fully charge all ready-to connect batteries.
• All battery interconnect cables should be the same wire gauge (AWG) and length, and come from the same brand. Otherwise, the impedance will be inconsistent, resulting in unbalanced charge and discharge performance.
• Connect your batteries one by one in parallel. Secure all cable connections between the cable lugs and terminals. Please do not connect batteries in series.
When determining the cable size (AWG) for your system, there are two factors to consider:
• The size of the electrical load you want to power.
• The distance between the electrical load and your batteries.
For reference, see the following chart:

HOW TO PROPERLY STORE BATTERIES

We recommend bringing our battery to a 100% state of charge, or at least a 30%-50% state of charge. Then disconnect the battery from any load by removing the terminal cables. Highly recommended charging the battery every 6 months when not in use to prevent over-discharge.

HOW TO CHARGE THE BATTERY

The optimal charging current for a single lithium battery is around 20 amps, while the maximum charging current is 50 amps. The amount of charging current is determined by your DC-DC charger, charge controller, or other compatible lithium battery charger you use.
When the battery is fully discharged at a continuous 1 00A, we do NOT recommend re-charging it at 50A immediately, which will trigger high-temperature charging protection.
