What we make
Power solutions, shaped around the job.
From battery packs to supporting electronics, start with the equipment and the power it needs.
LiFePO₄ battery systems
Battery options for solar, backup and other applications suited to LiFePO₄ chemistry.
Custom configurations
Talk through voltage, capacity, dimensions, connectors and the runtime you expect.
Electronics, power & repair
PCB and module assembly, chargers, BMS, inverters, custom electronics, service and repair.
Applications
Battery systems for the work you need to do.
The right pack depends on the equipment, load, runtime, charging method and available space. These are some of the applications you can discuss with E4tech.
E-scooters & electric mobility
Replacement and custom battery-pack enquiries for electric vehicles and mobility equipment.
Solar energy storage
Discuss battery options for solar systems and everyday energy storage.
UPS & backup power
Talk about a battery matched to your inverter, load and backup requirement.
Industrial & portable equipment
Custom pack requirements for tools, control equipment and other battery-powered devices.
Battery configuration
A good fit starts with the right details.
A battery is more than a voltage and capacity number. These are the points that help shape a suitable pack.
Cell chemistry
Discuss lithium-ion or LiFePO₄ based on the use, charging setup and operating requirements.
Voltage & capacity
Share the equipment rating, load and the backup or runtime you want from the pack.
BMS & charging
The battery management system and charger need to suit the pack chemistry and configuration.
Size & connections
Dimensions, enclosure, cable length and connector type all affect how the pack fits your device.
