As robotics technology advances across industries—from logistics and manufacturing to home assistants and healthcare—selecting the right battery has become critical for optimal performance. With so many options available, how do you pick the best power solution for your robot? This guide breaks down the key factors to consider.

Key Considerations When Selecting a Robot Battery

① Energy Density & Runtime

High Energy Density = Longer operation between charges (e.g., Li-ion NMC for lightweight robots).

LiFePO4 for stability & longevity (2,000+ cycles).

Calculate Runtime:

Operating Time (h) = Battery Capacity (Ah) ÷ Robot Power Draw (A)

② Safety & Reliability

✔ BMS (Battery Management System) – Prevents overcharge, overheating, and short circuits.

✔ Certifications – UL, CE, UN38.3 for transport safety.

✔ Thermal Stability – Critical for industrial robots in high-temperature environments.

③ Weight & Form Factor

Drones/AGVs → Ultra-light polymer lithium batteries.

Industrial Arms → High-power modular battery packs.

④ Charging Speed & Efficiency

Fast-charging (1-2 hrs) vs. standard charging (4-6 hrs).

Swappable battery systems for 24/7 operations.

Battery Types Compared

Type Best For Pros Cons

Li-ion NMC Lightweight robots, drones High energy density, fast charging Shorter lifespan (~800 cycles)

LiFePO4 Heavy-duty robots, AGVs Long lifespan, thermal stability Heavier, lower energy density

Solid-State (Emerging) Medical robots Ultra-safe, no leakage Expensive, limited supply

Common Mistakes to Avoid

❌ Ignoring Peak Current Needs – Ensure the battery can handle sudden power surges.

❌ Choosing Based on Price Alone – Cheap batteries often lack proper safety features.

❌ Overlooking Environmental Conditions – Outdoor robots need IP65+ waterproofing.

Why Choose First Power（Yi zhan battery） Robot Batteries?

✔ Custom Solutions – From 12V to 72V systems for all robot types.

✔ Smart BMS – Real-time monitoring via Bluetooth/Wi-Fi.

✔ Rugged Design – Vibration-resistant for industrial use.

✔ Warranty – Industry-leading support.
