A mixed chemistry battery is provided. The mixed chemistry battery includes a reference module having a first chemistry and a battery module having a second chemistry that is different that the first chemistry, the battery module is connected to the reference module in series. The mixed chemistry battery also includes a battery monitoring system configured to monitor an open circuit voltage of the reference module, an open circuit voltage of the battery module, and a current flow through the reference module and the battery module. The battery monitoring system is further configured to calculate a state-of-charge (SOC) and state-of-health (SOH) of the battery module based at least in part on a SOC of the reference module.
