This battery holder is made to hold two 18650-type batteries, such as our INR18650HG2 batteries. Refer to the image below, which shows those batteries installed in this holder.

The holder has individual pins, on the bottom side, which are connected to each battery terminal. This allows you to wire (configure) this holder for series-connected cells or parallel-connected cells. On the inner part of the holder are imprinted markings and text to indicate how to install batteries for series or parallel configurations.

Care must be taken when setting up this holder with batteries in parallel; refer to the Parallel Cells Note concerning precautions for connecting parallel cells.

Precautionary Notes:
Parallel Cells Note: Caution must be used when connecting two cells in parallel. Both cells must be at the same voltage level; otherwise, if one cell has a lower voltage than the companion cell, the higher voltage cell will discharge into the lower voltage cell in an attempt to bring the two cells to the same voltage. This will eventually balance out, but if the voltages of the two cells differ enough, the resulting current through both cells can be high enough to cause the cells to overheat or worse.
Series Cells Note: When cells are connected in series, you need a special battery charger and controller that are specifically made to charge and balance series connected cells.
