1. A battery system, comprising:
- a fixed battery pack;
a replaceable battery pack; and
a battery controller configured to;
detect electrical characteristics of the fixed battery pack,detect electrical characteristics of the replaceable battery pack,compare the electrical characteristics of the fixed battery pack with the electrical characteristics of the replaceable battery pack to determine a charge state of the replaceable battery pack and the fixed battery pack relative to a predetermined charging threshold, andcontrol either or both of the fixed battery pack and the replaceable battery pack to power one or more motors based on the comparison between the electrical characteristics of the fixed battery pack and the electrical characteristics of the replaceable battery pack.

Abstract
A battery for a vehicle having a fixed battery pack and a replaceable battery pack. The replaceable battery pack has electronic or mechanical locks to semi-temporarily hold the replaceable battery pack in place. The fixed battery pack is held in place via permanent or semi-permanent fasteners such as bolts. A battery controller controls the replaceable battery pack to power motors of the vehicle before controlling the fixed battery pack to power motors of the vehicle.
