Dependable Backup Power Solution

The Exotronic 12V 20Ah Alpha Series is purpose-built for compact energy systems requiring consistent, deep-cycle performance. With its highly efficient LiFePO4 chemistry and integrated smart BMS, it delivers stable backup power for security systems, emergency lighting, communication equipment, and other essential low-demand devices. This makes it perfect for users seeking a long-lifespan alternative to AGM or lead-acid batteries in small-scale installations.

Ideal for Portable and Off-Grid Electronics

Its lightweight footprint and strong IP67 protection make this battery an excellent choice for portable power stations, surveillance units, scientific instrumentation, small off-grid setups, and remote monitoring systems. Whether supporting a caravan setup, tiny home, marine electronics, industrial control systems, or battery-powered tools, the 20Ah Alpha Series ensures uninterrupted performance where reliability is critical.

Precision Power for Technical Installations

For engineers and system designers, the battery’s stable discharge curve, enhanced thermal management, and intelligent low-voltage cut-offs provide the accuracy required for equipment such as DC UPS modules, IoT gateways, and energy-efficient automation systems. This precision is further supported by its Bluetooth-enabled monitoring for real-time insight into cell health, current flow, temperature, and charge status.

IP67-Rated Durability for Harsh Environments

The rugged casing and sealed design offer full dust protection and resistance to water immersion up to 1m for 30 minutes, making this unit ready for exposed or environmentally demanding installations. From marine electronics and RV accessories to industrial sensor housings and off-grid power banks, the Alpha Series withstands moisture, debris, and vibration without compromising performance.

Advanced Safety and Long-Term Protection

  • Inherently safe LiFePO4 chemistry with high thermal stability
  • Strong ABS housing engineered for impact resistance and longevity
  • Pressure-relief rupture discs for added safety in cell protection
  • Comprehensive over-charge, over-discharge, and short-circuit safeguards

Smart BMS Oversight

The integrated JBD BMS continuously manages voltage, temperature, and current to prevent damage and extend lifespan. This ensures optimal performance even under fluctuating loads often found in small solar systems, workshop tools, and backup power applications. The system’s data-driven cell balancing increases cycle life and maximises usable capacity for everyday and intermittent-use scenarios.

Optimised for Efficiency and Longevity

Featuring premium aluminium-cased prismatic cells, the 20Ah Alpha Series delivers exceptional service life with up to 3,000 cycles, maintaining consistent voltage output and high round-trip efficiency. Its low self-discharge rate supports long-term storage—perfect for infrequently used backup systems, seasonal equipment, or remote installations requiring reliable standby power.

Bluetooth Smart Monitoring

With the JBD Bluetooth interface, users can access detailed battery analytics including individual cell voltages, internal temperatures, load current, SOC, and protective MOSFET status. This feature is especially beneficial for technicians managing solar charging systems, off-grid controllers, and precision backup hardware.

Perfect for Compact Energy Demands

The Exotronic 12V 20Ah Alpha Series delivers powerful performance in a small form factor, supporting applications such as portable electronics, caravan accessories, marine navigation equipment, security systems, industrial automation modules, and tiny home installations. Wherever dependable small-capacity lithium power is required, this battery provides unmatched reliability and versatility.
