FAQs About 48V, 96V and 144V Heavy-Duty AMR Battery Systems

You need more than just a single lithium ion battery pack​. You need a veteran manufacturer who has been in the field for 10+ years to save your project time, build your brand and grow your profits. Let Bonnen Battery help you achieve business success.

The right voltage depends on your traction controller, motor power, vehicle weight, payload, duty cycle, and required operating time. A 48V system can suit medium to heavy-duty AMRs with moderate traction power, while 96V is better suited to many heavier industrial AGVs and AMRs. For higher-power autonomous transporters, a 144V architecture can deliver more power without requiring proportionally higher current, but the final voltage should always be matched to the vehicle’s complete electrical architecture.

It can be, depending on the vehicle. The 48V 304Ah configuration provides 14.59kWh of nominal energy and is based on a single low-profile battery module. Whether that is enough depends on the AMR’s total mass, payload, motor power, speed, grade, operating hours, auxiliary loads, and charging opportunities rather than battery capacity alone.

Yes, a 96V 304Ah battery system can be a good fit for heavy-duty AGVs and AMRs that need more traction power and energy than a typical 48V platform. The Bonnen configuration uses two coordinated 48V 304Ah modules to provide 29.18kWh of nominal energy, with the final system engineered around the traction controller, BMS, high-voltage components, charging system, and vehicle duty cycle.

A 144V 304Ah battery is worth considering for high-power heavy-duty AMRs, large AGVs, and autonomous industrial transporters carrying substantial loads. The three-module configuration provides 43.77kWh of nominal energy and allows higher system power at the same current level than the 48V or 96V versions. Final suitability still depends on motor requirements, payload, grade, operating time, and controller voltage limits.

The amp-hour capacity remains 304Ah, but system voltage and total energy increase as additional modules are added in series. The 48V system provides 14.59kWh, the 96V system provides 29.18kWh, and the 144V system provides 43.77kWh. Higher voltage also allows more power to be delivered at the same current, which can be useful for heavier vehicles and higher-power traction systems

For a heavy-duty traction application, we do not recommend treating two independent smart batteries as ordinary batteries and simply connecting them in series. A 96V AMR battery should be engineered as one coordinated system with module monitoring, a master-slave BMS architecture, appropriate contactors, pre-charge circuitry, fusing, current sensing, communication, and system-level fault management.

Yes, but they should be designed as a coordinated 144V traction battery rather than three unrelated standalone batteries. In Bonnen’s architecture, three 48V 304Ah modules can form a 144V 304Ah system, with the modules supervised through a master-slave BMS and supported by appropriately rated high-voltage protection and control components.

This battery platform is intended for larger industrial mobile robots rather than small warehouse shelf robots. Typical applications include heavy-duty flatbed AMRs, automotive chassis transport AGVs, EV battery pack transport AMRs, die and mold transport AGVs, steel and metal material transporters, heavy-duty tugger AGVs, aerospace component transporters, and large custom autonomous forklifts.

Yes, the platform is intended for multi-ton autonomous transport applications, but vehicle weight alone is not enough to select the battery. Payload, acceleration, maximum speed, road grade, wheel and drivetrain efficiency, motor power, operating hours, charging opportunities, and installation space all need to be considered when sizing a battery for a multi-ton AMR.

LiFePO4 is well suited to many industrial AMR and AGV applications because it combines cycle-life potential, thermal stability, high-current capability, and practical durability. Bonnen’s 48V 304Ah base module uses LiFePO4 cells and is designed as a building block for heavy-duty industrial traction battery systems.

The base 48V 304Ah battery module uses an aluminum enclosure rated to IP67. This makes the module suitable for demanding industrial environments where protection against dust and temporary water exposure is important, although the complete vehicle installation, connectors, cables, vents, and external components must also be designed to maintain the required environmental protection level.

The base module measures approximately 580 × 410 × 260mm and weighs about 105kg. A complete 96V or 144V system uses multiple modules, so the finished system weight will also include high-voltage control components, cables, connectors, mounting hardware, and other project-specific equipment.

The 580 × 410 × 260mm module was designed as a relatively low-profile building block for industrial mobile robots. Depending on the chassis, modules can be evaluated for central, side-by-side, or distributed installation while considering ground clearance, wheelbase, axle loading, center of gravity, connector access, and future maintenance.

The 48V 304Ah base module is specified for up to 300A continuous discharge and up to 600A peak discharge, with the permitted peak-current duration subject to engineering confirmation. The final vehicle-level current and power rating also depends on the BMS, contactors, fuse, cables, connectors, thermal conditions, and traction controller.

There is no universal kWh value for a heavy-duty AMR because two robots with the same payload can have very different energy consumption. Battery capacity should be calculated from the vehicle’s real duty cycle, including loaded and unloaded travel, acceleration, speed, gradients, turning, idle time, onboard electronics, operating hours, charging opportunities, and the usable SOC window.

Start with the AMR’s average energy consumption during a representative working cycle rather than dividing battery kWh by motor nameplate power. Traction motors rarely operate continuously at rated power, so the correct calculation should consider loaded travel, unloaded travel, acceleration, stopping, idle periods, auxiliary loads, regenerative braking if available, usable battery energy, and the required reserve at the end of the shift.

Yes. Multi-module configurations are managed through a coordinated master-slave BMS architecture. Slave monitoring units supervise individual battery modules while the master BMS manages system-level functions such as monitoring, protection, switching, communication, and fault handling across the complete traction battery.

Yes, the communication interface and message requirements can be developed around the target AMR controller, charger, and vehicle architecture. When requesting a custom AMR battery, it is helpful to provide your controller documentation, communication protocol, required messages, baud rate, fault-handling requirements, and any available CAN database or interface specification.

Yes. The charging interface and charging strategy should be matched to the system voltage, battery capacity, operating schedule, available charging time, and the AMR’s working pattern. This is especially important for robots using opportunity charging between tasks or short charging windows during multi-shift operation.

Not every heavy-duty AMR requires liquid cooling. Thermal requirements depend on continuous current, peak power, ambient temperature, duty cycle, enclosure location, charging rate, available airflow, and how frequently the vehicle operates under high load. The thermal solution should therefore be selected during system engineering rather than assuming that every AMR battery needs the same cooling method.

Yes. Battery packaging can be developed around available chassis space, wheel position, structural members, motors, ground clearance, axle loading, and service access. Using the common 48V module as a building block also makes it possible to evaluate different central or distributed layouts for 48V, 96V, and 144V vehicle architectures.

The most useful information includes the AMR application, vehicle weight, maximum payload, motor voltage and power, continuous and peak power demand, maximum speed, grade, required operating time, charging method, charging window, available battery space, communication requirements, and environmental conditions. These details allow the battery system to be sized around the actual vehicle rather than selecting a battery only by voltage and Ah.

That is not a problem. You can send the information you already have, such as motor voltage, motor power, payload, approximate operating hours, available installation space, or even just the vehicle concept. Bonnen’s battery engineering team can use the available information to identify what additional data is needed before finalizing the battery configuration.

Yes. Automotive chassis transport AGVs and EV battery pack transport AMRs are among the types of heavy autonomous transport applications this modular platform is intended to support. The final battery is engineered around the transporter’s payload, traction power, duty cycle, required operating time, charging strategy, chassis space, vehicle communication, and service requirements rather than using a generic off-the-shelf battery.
