2.5 Series Connections
Series connections can lead to high voltages and should be carefully configured by
experienced and qualified personnel only. Please refer to proper codes and guidelines for
safe installation. Refer to the latest edition of the National Electric Code for additional
details. For series installations, it is recommended a cutoff voltage be set to 23.25V per
series module.
Ultralife suggests contacting the factory for assistance when connecting MKMs in series,
as external diodes may be required, as well as proper fusing and protection for safety.
2.6 Environmental Controls
Although the Lithium batteries in the MKM series are extremely robust, it is suggested they
be used in a controlled temperature atmosphere of between 5C and 45C for optimum
performance. Environmental exposure outside of these limits will result in decreased
overall performance and possible decrease in cycle life.
