Battery bank more than 4 months

  • I have purchased three 48v 100ah batteries for my solar system that I intended to be permanently installed in parallel why do you say not to leave them more than 4 months?


  • 1) If you mean to leave the batteries for more than 4 months without use, Generally speaking, if you plan to leave it on hold for a long time, we recommend that you turn it on every 30-40 days after full charge to check the condition of the battery 
    2) If you mean whether the battery purchase time between parallel connections can exceed 4 months, different brands of lithium batteries cannot be connected, because the batch of cells is not the same. Even if it is the same brand, If the purchase interval is more than 4 months, it is also not recommended to connect. Because the energy decay between the cells is not consistent.
