How to connect two 12V batteries with PCM in series

The connection of the batteries with the 12V PCM is the same as the connection of any other batteries. Some additional things need to be observed:  before the assembly of the pack in series, first charge individually each of the batteries to full. Observe the voltage levels for the discharge of the batteries. The batteries should not be discharged to too low voltage levels. It is recommended to stop discharging at 11.5V or 11.8V per battery in the pack. This means to stop discharging at 23V for a pack of 2 cells in series.

From time to time it may be necessary to have the batteries charged individually to the full. That is why it may be good to have the cabling to each battery ready to allow the charging of individual battery in the pack.
