Key Features

Quick-Release “Hot-Swap” Design: The battery features a “plug-and-play” mechanism, allowing researchers and developers to swap depleted units for fresh ones in seconds, minimizing downtime during long testing sessions.
Intelligent BMS (Battery Management System): An integrated proprietary system monitors individual cell status in real-time. It provides accurate power calculations and ensures stable energy output even during high-current maneuvers like jumps or sprints.
Eight-Fold Safety Protection:
- Self-Discharge Protection: Automatically discharges to a safe level (approx. 65%) if left unused for long periods to prevent cell swelling.
- Temperature Control: Built-in sensors prevent charging or discharging at unsafe temperatures (typically outside 5°C to 55°C).
- Electrical Safeguards: Includes overcharge, over-discharge, short-circuit, over-voltage, and under-voltage protection.
Built-in LED Indicators: A simple visual display on the battery casing allows you to check the remaining charge level without powering on the robot.

Usage Best Practices

To maintain the longevity of your R1 battery, it is recommended to stop operation when the robot indicates low power (typically one bar) and avoid storing the battery at 0% or 100% for extended periods.
