Ampere Battery Repair, Replacement & Custom Lithium Battery Solutions

Lion Battery provides Ampere electric scooter battery testing, repair, cell replacement, refurbishment, BMS services and custom lithium battery solutions for compatible Ampere battery packs.

Ampere is an electric-scooter brand of Greaves Electric Mobility, with models including Nexus, Magnus G Max, Magnus Neo and Reo Vyb. Current Ampere models use lithium battery systems, with LFP used in several current models.

Important: Lion Battery is an independent battery service/manufacturing company and is not an official Ampere service centre or affiliated with Ampere/Greaves Electric Mobility. If your battery is still under manufacturer warranty, check the official Ampere service channel first. Ampere publishes its current warranty terms and authorized dealer/service network.

Ampere Battery Repair

An Ampere battery that has developed reduced range, charging problems or power cut-outs should be tested before replacing the complete pack.

Possible causes include:

• Weak Cell Groups
• Cell Imbalance
• Reduced Battery Capacity
• High Internal Resistance
• BMS Fault
• Wiring or Connector Problems
• Charging Problems
• Battery Age

We can inspect the battery and determine whether cell replacement, BMS service, refurbishment or complete battery replacement is the more appropriate solution.

Ampere Battery Cell Replacement

Depending on the battery design and condition, weak cell groups may be replaceable.

Cell replacement should consider:

• Original Chemistry
• Cell Capacity
• Discharge Capability
• Internal Resistance
• Series/Parallel Configuration
• Cell Matching
• BMS Compatibility

Do not mix incompatible cell chemistries or significantly different cell specifications.

Ampere Battery BMS

The BMS is responsible for monitoring and protecting the battery pack.

Possible BMS functions include:

• Cell Voltage Monitoring
• Overcharge Protection
• Over-Discharge Protection
• Overcurrent Protection
• Temperature Monitoring
• Cell Balancing
• Short-Circuit Protection

For smart EV batteries, communication compatibility can also be important. A replacement BMS should therefore be selected based on the exact battery model and electrical/communication requirements.

Ampere Battery Testing

Our testing can include:

Battery Voltage Test

Checks the overall battery voltage.

Cell-Group Voltage Test

Identifies significant voltage differences between cell groups where accessible.

Internal Resistance Test

Helps identify weak or abnormal cells.

Capacity Test

Measures the battery’s actual capacity under defined test conditions.

BMS Test

Checks available BMS protection and monitoring functions.

Charge & Discharge Test

Evaluates battery behavior under controlled conditions.

Ampere Battery Models

Ampere has sold different battery configurations across different models and model years. Therefore, battery voltage and chemistry should always be confirmed from the battery label and vehicle specifications before repair or replacement.

Current Ampere models include:

• Ampere Nexus
• Ampere Magnus G Max
• Ampere Magnus Neo
• Ampere Reo Vyb

Ampere’s current website lists these models and describes its newer battery systems, while its warranty documentation specifies different warranty periods depending on model and sale date.

Custom Ampere Replacement Battery

If a replacement battery needs to be developed, Lion Battery can evaluate:

• Voltage
• Ah Capacity
• Battery Energy
• Cell Chemistry
• Battery Dimensions
• BMS
• Connector
• Charger
• Communication
• Mounting
• Current Requirement

The exact model number and original battery label should be checked before quoting a replacement.

Ampere Battery Refurbishment

Where technically appropriate, refurbishment may include:

Battery Inspection → Cell Testing → BMS Testing → Weak Cell Replacement → Cell Matching → Assembly → Capacity Testing → Final Inspection

Refurbishment is not suitable for every damaged or degraded battery; the battery condition must be evaluated first.

Ampere Battery Safety

Lithium battery packs contain significant stored energy. Do not open, short-circuit, puncture, weld or modify an EV battery without suitable equipment and technical expertise.

If the battery is:

• Swollen
• Physically damaged
• Extremely hot
• Leaking
• Producing smoke
• Showing signs of thermal failure

stop using it and move away from the battery.

For batteries under warranty, use the authorized Ampere service channel first. Ampere also recommends using its authorized charger and charging in a shaded or ventilated area.

Frequently Asked Questions

Can you repair an Ampere battery?

Yes, compatible Ampere battery packs can be inspected and tested to determine whether repair or refurbishment is technically possible.

Can you replace Ampere battery cells?

Depending on the pack design and condition, weak cell groups may be replaceable.

Can you replace the Ampere BMS?

A compatible BMS can be evaluated based on the exact battery configuration and communication requirements.

Can you make a custom Ampere replacement battery?

A custom replacement can be evaluated after checking the original battery’s voltage, capacity, dimensions, chemistry, BMS and connector.

Should I repair my Ampere battery or buy a new one?

Battery testing should be performed first. If only specific cell groups or the BMS have failed, repair may be possible; extensive degradation may make complete replacement more appropriate.
