Custom 80V 560Ah Lithium Battery Solutions for Kramer 5055e and Other Electric Wheel Loaders

1. Electric Wheel Loader OEMs

OEMs receive a battery platform that can be designed around the machine instead of forcing the machine around a fixed catalog battery.

Bonnen Battery can support:

• Custom voltage and capacity
• Pack layout design
• CAN communication
• Charger matching
• Prototype development
• OEM branding
• Low-volume and production planning

2. Equipment Electrification and Retrofit Companies

Retrofit companies need the battery, motor controller, charger, and vehicle control system to work as one system.

A project-specific battery helps reduce risks related to:

• Incorrect voltage
• Limited installation space
• Controller startup faults
• CAN communication errors
• Charging conflicts
• High-current cable sizing
• Poor weight distribution

3. Heavy Equipment Dealers and Distributors

Dealers can offer a custom battery solution when an original battery is unavailable, too expensive, or no longer supported.

Bonnen Battery can help review the old battery label, drawings, connector details, CAN data, charger information, and machine power demand before proposing a replacement.

4. Equipment Rental Companies

Rental fleets need batteries that are simple to monitor and suitable for daily use.

An external LCD, clear fault reporting, sealed housing, and project-specific charging system can make fleet operation easier. Rental companies may also request service labels, operating instructions, and standard connector layouts across a fleet.

5. Construction, Mining, and Agricultural Fleet Owners

Fleet owners usually focus on runtime, charging time, reliability, and total operating cost.

A properly sized battery helps avoid two common problems:

• A battery that is too small and requires frequent charging
• A battery that can store enough energy but cannot safely deliver the required current

Energy capacity and current capability must both match the job.

6. Municipalities and Public Works Departments

Municipal equipment may work near homes, schools, parks, hospitals, and indoor public facilities.

Electric loaders can be useful where low noise and local emission control are important. The battery can be designed around daily routes, scheduled charging, seasonal temperature, and maintenance access.

7. Loader Service and Repair Companies

Service companies may need a replacement when the original pack has failed or when the machine manufacturer no longer supports the battery.

Bonnen Battery can evaluate the old battery system, but a replacement requires more than copying its voltage. Communication, contactor logic, charger control, mounting, and fault handling must also be understood.

8. Battery and Vehicle System Integrators

System integrators need clear electrical limits and reliable communication.

Bonnen Battery can work with the integrator to define:

• Charge and discharge current limits
• CAN message lists
• Contactor control
• Pre-charge timing
• Fault behavior
• Charger communication
• Display data
• Parallel control logic

Compatible Custom Battery Development Projects

Important: The brands listed above are examples of equipment categories that may require a custom lithium battery solution. They do not indicate that the Bonnen Battery 80V 560Ah battery is a direct replacement for every listed machine. Every application is evaluated individually based on voltage, dimensions, power demand, communication protocol, and installation requirements.

Suitable Equipment Types

1. What is the Bonnen 80V 560Ah lithium battery for electric wheel loaders?

The Bonnen 80V 560Ah battery is a 44.8 kWh custom lithium battery system developed for an electric wheel loader project involving the Kramer 5055e.

It has a 65–91.25 V operating range, 300 A continuous discharge, 500 A peak discharge for 3 seconds, an IP67 steel housing, and an external LCD.

2. Can Bonnen Battery customize a lithium battery for other electric wheel loader brands?

Yes. Bonnen Battery can develop custom battery systems for other electric wheel loader brands and models.

The customer must provide the loader’s voltage, capacity target, current demand, installation space, connector details, charger information, and communication requirements.

3. How much energy does an 80V 560Ah wheel loader battery store?

An 80 V, 560 Ah battery stores 44.8 kWh of rated energy.

The calculation is:

80 V × 560 Ah = 44,800 Wh, or 44.8 kWh.

Usable energy may be lower because the BMS keeps safety limits at the top and bottom of the operating range.

4. How long will a 44.8 kWh battery run an electric wheel loader?

Runtime depends on the loader’s average power use.

For example:

• At an average load of 10 kW, the theoretical runtime is about 4.48 hours.
• At an average load of 15 kW, the theoretical runtime is about 2.99 hours.
• At an average load of 20 kW, the theoretical runtime is about 2.24 hours.

Real runtime will be lower or higher depending on usable energy, hydraulic use, driving, slopes, temperature, attachments, and idle time.

5. Is a 560Ah battery better than a smaller loader battery?

A 560 Ah battery provides more energy at the same voltage, but larger is not always better.

A larger battery may increase runtime, weight, cost, charging time, and installation difficulty. The correct capacity is the smallest practical capacity that safely meets the required work shift and power demand.

6. What does 4,000 cycles at 80% DOD mean?

It means the battery has a stated test target of 4,000 charge-discharge cycles when each test cycle uses 80% of the battery’s available capacity under defined conditions.

DOD means depth of discharge. An 80% DOD cycle uses 80% of the battery’s available energy before recharging.

7. Can this IP67 battery work in rain, mud, and dusty construction sites?

It is designed for demanding outdoor conditions, but the final installation still matters.

Connectors must be locked, seals must remain undamaged, drain paths must stay clear, and cables must be protected from impact and abrasion. The machine installation should not expose the battery to conditions beyond its approved design.

8. Does the 80V 560Ah battery include a BMS?

Yes. A high-capacity loader battery requires a BMS to monitor cells, temperatures, current, state of charge, and fault conditions.

The BMS settings and communication must be configured for the specific loader project.

9. Can Bonnen Battery match my loader’s CAN protocol?

Bonnen Battery can review and customize CAN communication for qualified projects.

The customer should provide a CAN protocol document, DBC file, message list, CAN log, or access to the existing battery and machine. CAN matching cannot be confirmed from connector photos alone.

10. Does this custom loader battery include an external LCD?

Yes. The 80V 560Ah platform includes an external LCD.

The exact information shown depends on the BMS and display setup. Typical data includes state of charge, voltage, current, temperature, status, warnings, and fault codes.

11. What charger should I use for an 80V 560Ah lithium battery?

The charger must match the battery’s maximum charge voltage, charging current, cell chemistry, BMS logic, connector, and communication method.

The battery supports up to 200 A continuous charging, but the selected charging current should also match the available AC supply, cooling system, charge-time target, and battery-life goal.

12. How long does it take to charge a 560Ah electric wheel loader battery?

Charging time depends on the charger current and the amount of energy being replaced.

As a simple estimate:

• A 100 A charger would need about 5.6 hours to deliver 560 Ah.
• A 200 A charger would need about 2.8 hours to deliver 560 Ah.

Actual charging takes longer because current may reduce near full charge and because of charging losses, temperature limits, BMS control, and the starting state of charge.

13. Can two 80V 560Ah batteries be connected in parallel?

Yes, but only when parallel operation is designed into the battery and machine system.

Each pack should have coordinated BMS logic, protection, contactors, fuses, pre-charge control, communication, and balanced high-current cables. Two standard packs should never be connected in parallel without approval.

14. What capacity would two 80V 560Ah batteries provide in parallel?

Two matching 80V 560Ah packs in parallel would provide a combined rated capacity of 1,120 Ah and a combined rated energy of 89.6 kWh.

The system voltage would remain 80 V. The actual current limits would depend on the BMS strategy, wiring, contactors, fuses, cooling, and controller.

15. Can this battery replace an older lithium battery in an electric loader?

Possibly, but voltage and size are not enough to confirm compatibility.

Bonnen Battery must also check:

• Voltage range
• Continuous and peak current
• CAN communication
• Contactor logic
• Pre-charge system
• Charger control
• Connectors
• Mounting
• Cooling
• Low-voltage power
• Fault handling

A replacement battery must act correctly inside the complete machine system.

16. Can this battery be used for a diesel-to-electric wheel loader conversion?

Yes, the platform can be evaluated for loader conversion projects.

The conversion company must define the motor, controller, hydraulic motor, DC/DC converter, charger, vehicle control unit, power demand, installation space, weight target, and expected runtime.

17. Is a steel battery case suitable for an electric wheel loader?

A steel enclosure can provide strong impact resistance, good structural support, and practical mounting for heavy equipment.

Its main trade-off is weight. The steel thickness, internal frame, mounting points, corrosion protection, and total battery weight should be reviewed during mechanical design.

18. Can Bonnen Battery make the loader battery housing from aluminum?

Yes, aluminum may be considered when lower weight or corrosion resistance is important.

However, an aluminum enclosure may require a different wall thickness, frame structure, welding process, sealing design, and cost. The best material depends on the machine and project target.

19. Can the battery size and connector position be customized?

Yes.

Bonnen Battery can adjust the pack layout, enclosure dimensions, mounting points, connector type, connector direction, cable outlet, LCD location, and service access, subject to cell layout and safety limits.

20. Can Bonnen Battery add my company’s logo and model number?

Yes. OEM labels, company logos, battery model numbers, serial numbers, warning labels, and customer-specific packaging can be discussed for qualified projects.

Branding is completed after the technical design is approved.

21. How do I start an electric wheel loader battery project with Bonnen Battery?

The process has three steps:

1. Send the machine, battery, and operating information.
2. Review the proposed electrical and mechanical design.
3. Approve the specification, drawing, communication, and charging setup.
