How to assemble large -capacity batteries?battery for solar energy storage Manufacturing

  Ni-MH battery pack manufacture

  For example, want a large -capacity battery of 6000mAh, 16V. If the voltage of a battery is 4V and the capacity is 1200mAh, then you need 20 battery cells. That is, 4 battery cells are required to form a series of unit groups to become a 16V battery pack. The capacity of such a battery pack is 1200mAh, and then connect 5 such unit battery packs. Large -capacity lithium batteries.

  The 12V large -capacity battery refers to a battery nominal voltage of 12V and a battery capacity of more than 20000mAh. 12 Lithium battery is combined with 3 3.7V lithium batteries. The voltage full of a single lithium battery is 4.2V. Generally, it is also called 4V. The voltage of the series battery is added. Power also = 12V, which is what we call the 12V lithium battery. Some battery capacity can reach 20AH, or 50AH. The more the battery is connected, the greater the capacity. According to the formula of physics: in parallel circuit: total = i1+i2+i3. Generally, batteries with a capacity of more than 20000mAh are called large -capacity batteries.

  1. The voltage difference difference between the battery cell used should not be too large, it is best to be within 20mv;

  2. It is not recommended to use the same type of batteries of different manufacturers for assembly, because manufacturers will cause inconsistency between the working efficiency between the battles due to the differences between the production technology and the formula of the battery material, which will easily damage the battery.

  3. Even the lithium battery cells of the same manufacturer cannot be mixed with old and old;

  4. Even the cells of the same manufacturer, it is recommended to use the same batch of battery cells;
