Abstract
The present disclosure includes a method that includes receiving, via a processor disposed within a lithium ion battery module, a voltage signal associated with a resistor coupled to a negative terminal of the lithium ion battery module. The negative terminal of the lithium ion battery module is coupled to a negative terminal of a lead acid battery module. The method also includes determining, via the processor, one or more properties associated with the lead acid battery module based on the voltage signal.
