Battery Performance and Discharge Capability
This battery is specified with a nominal voltage of 72V and a capacity of 52.5Ah. These ratings give a calculated nominal energy capacity of 3,780Wh, approximately 3.8kWh.
The battery is advertised with a maximum peak discharge current of 150A. This figure describes a peak limit and should not be interpreted as a continuous current rating. The supplier does not specify how long the peak rating can be maintained or the applicable thermal conditions.
The battery’s suitability for a particular electric motor and controller depends on the complete electrical system, including operating current, wiring, connectors, protection settings and installation conditions.
LG MJ1 Cells and 20S15P Configuration
The battery uses LG MJ1 cells rated at 3500mAh, arranged in a 20S15P configuration. This means there are 20 series-connected cell groups and 15 cells connected in parallel within each group.
The parallel arrangement provides a nominal capacity of 52.5Ah, while the series configuration establishes the battery pack’s nominal voltage.
These documented characteristics help technicians evaluate the battery for compatible projects. However, the cell configuration alone does not confirm the installation requirements of any particular electric motorcycle.
Bluetooth Battery Management System
The LG MJ1 battery includes an integrated Battery Management System with Bluetooth functionality. A BMS is an important component in a rechargeable battery assembly, helping manage the electrical operating conditions of the pack.
Bluetooth functionality provides a wireless interface, although the supplier does not identify the supported application, available readings or configuration controls.
Customers who require specific monitoring functions should confirm the BMS model and software compatibility before purchase.
Metal Battery Enclosure and Installation
The battery is supplied in a metal enclosure intended to provide additional physical protection. Its published weight is 14.9kg, an important consideration when planning mounting, handling and weight distribution.
The supplier does not publish the enclosure dimensions, mounting measurements, connector specifications or charging port details. These should be verified before selecting the pack for an existing motorcycle or custom frame.
A protective metal case should not be interpreted as proof of waterproofing, impact certification or compliance with a particular ingress protection standard.
Charging and Riding Range
The approximately 3.8kWh nominal capacity provides an indication of the energy stored in the battery, but it does not guarantee a particular riding range. Actual distance depends on the vehicle’s efficiency, terrain, speed, rider weight, temperature and riding style.
The product listing does not specify the charging time, maximum charging current, charging connector or included charger. Use only charging equipment confirmed as compatible with the pack’s electrical requirements.
Why Choose the LG MJ1 72V 52.5Ah Battery?
This battery combines documented LG MJ1 cells, a 52.5Ah capacity, 150A peak discharge capability and a Bluetooth-enabled BMS in a metal enclosure.
It is a battery option worth considering for experienced builders requiring a 20S15P pack with approximately 3.8kWh of nominal energy.
Compatibility with specific Talaria, Sur-Ron, E Ride Pro or Vector motorcycle models has not been confirmed by the source. Before purchasing in Germany, verify the physical fit, electrical connections, charging requirements and relevant safety documentation with the supplier.
