• Emergency Backup – trusted solution for home and business backup power systems

• Off-Road Ready – built to handle rugged Australian conditions and demanding outdoor use

Safety and Protection

• LiFePO4 chemistry for inherently safe operation

• Integrated BMS safeguards against overcharge, over-discharge, temperature extremes, short circuit and current overload

• Advanced pressure release system for added safety under fault conditions

• Active balancing technology ensures even cell wear and longer lifespan

Long-Lasting Performance

• Up to 3,000+ charge cycles for a service life of 10–12 years

• No memory effect – requires only occasional charging during storage (every 3 months)

• Low resistance brass connections reduce voltage drop, heat build-up and efficiency loss

Easy Monitoring & Operation

• On/Off button with intuitive 5-second activation/deactivation

• Bluetooth app monitoring available on Android and iOS for real-time data and alerts

• Clear low charge warnings prevent unexpected power loss

Bluetooth Smart

The JK BMS includes Bluetooth, allowing real time viewing of the individual cell voltages, battery temperature, current, state of charge, state of the charge/discharge MOSFETs and alarms.
