1. An electronic battery tester for use in configuring a plurality of storage batteries in a battery pack, comprising:
- a dynamic measurement circuit configured to measure a first dynamic parameter of a first storage battery;
a memory configured to store a second dynamic parameter from related to a second battery of the battery pack;
balance circuitry configured to provide an in-balance output if the second battery in the pack has a second dynamic parameter which is substantially equal to the first dynamic parameter.
