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
