1. A vehicle lift comprising:
a power system for actuating said vehicle lift, wherein said power system comprises a hydraulic pump;
one or more batteries for providing electrical power to said power system;
a height sensor; and
a battery management system (BMS) configured to monitor data related to said one or more batteries, wherein said data includes voltages and current draws for said one or more batteries, wherein said BMS is configured to monitor voltages and current draws during charging and discharging of said one or more batteries when said one or more batteries are electrically connected to said hydraulic pump,
wherein said vehicle lift is configured to be wirelessly synchronized with at least one additional vehicle lift to provide a coordinated lifting operation of a vehicle, wherein the synchronized vehicle lifts are configured to maintain the vehicle in a substantially level orientation during the coordinated lifting operation,
wherein upon performing the coordinated lifting operation, the vehicle lift is configured to determine, via the height sensor, a new height of the lift,
wherein said vehicle lift is configured to transmit data about said one or more batteries to the at least one additional vehicle lift,
wherein said vehicle lift is configured to determine, via said BMS, whether said one or more batteries has sufficient electrical power remaining to lower said vehicle after performing the coordinated lifting operation.
