Custom Batteries for Robots & UMVs

Custom Battery Packs for High-Performance Robotics

No same battery for two different robots. A warehouse AMR needs long shifts and fast swaps, a legged robot needs high current inside a tight body, and a field robot has to shrug off rain and temperature swings. That is why every battery pack we build starts with your robot, not with a catalog.

At CM Batteries, we engineer custom lithium battery packs for AMRs, AGVs, humanoid and legged robots, and agricultural, service and companion robots. Most of the projects we see run on 12V to 48V platforms, with 24V the most common, in LiFePO4 or NMC, with CAN 2.0B or RS485 communication and IP67 or IP68 protection where the work demands it.

Share your robot and its requirements, or size it first with our Battery Pack Configuration Calculator, and our engineers will reply with a proposal.

Custom Battery Packs for AMRs and AGVs

A logistics robot earns its keep by staying on the floor. We build the pack around your bay, your fleet software and your shift pattern.

What you are facing
How we build for it
The battery bay is fixed and every millimetre counts.
→ We lay out prismatic or 21700 cells to your bay, then add parallel strings for capacity inside the same footprint.
Fleet software needs live SOC and fault data.
→ CAN 2.0B or RS485 BMS reports SOC and SOH, with the protocol aligned to your controller. Details are shared under NDA.
Robots cannot idle while a pack charges.
→ Hot-swap capable designs, with BMS charge limits matched to your charger or dock. We have also delivered a sealed IP68 pack for warehouse floors.

Engineer Superior Robotics Batteries

For over a decade, CM Batteries has been the power behind the most demanding industrial robots, AMRs, and service machines. We’ve distilled this experience into five core pillars that ensure your robots operate safer, last longer, and perform smarter.

 

•

Intelligent BMS with CAN/RS485

Features CAN 2.0B compatibility for seamless integration with your robot’s control system. Our BMS employs intelligent algorithms to monitor State of Charge (SOC) and State of Health (SOH), enhancing range and charging efficiency. Hot-swap capability ensures continuous operation with zero downtime.

•

Modular & Scalable Design

Overcome space constraints with our flexible modular architecture. By connecting battery packs in parallel, we can customize the pack’s capacity and footprint to perfectly fit your unique dimensional and power requirements.

•

Diverse Chemistry Portfolio

Choose from a range of advanced chemistries including LiFePO4 for longevity and safety, or high-energy-density NCM. We offer both prismatic and cylindrical cell options, engineered into lightweight packs of various form factors.

•

Robust IP67 Enclosure

Built to withstand harsh environments. We provide complete structural engineering, including custom 3D-designed IP67 waterproof enclosures, ensuring protection and compliance with relevant certification standards.

•

Next-Gen Solid-State Technology

Prepare for the future with batteries that offer higher energy density, inherent safety, and a superior discharge profile. Ideal for next-generation high-end AMRs and heavy-duty robotic applications.
