Battery Reference

Current pack reference values and safety boundaries for the Asimov 1 battery.

The robot uses a rechargeable lithium-ion battery pack.

Reference data, not a charging procedure

These values identify the current pack design. They do not select or approve a charger, connector, fuse, switch, power-distribution design, emergency-stop integration, charging rate, or robot power-on procedure. Keep the pack disconnected until those procedures are validated.
