Why Choose the Rich Solar Alpha 1 Lithium Battery?
- Premium A+ Grade EV Cells: Delivers over 5,000+ lifetime charge cycles at 80% Depth of Discharge (DoD)—giving you over 3 times the lifespan of traditional lead-acid batteries.
- Internal Low-Temperature Heating: Never worry about winter charging freezes. Built-in smart heating triggers automatically when ambient temperatures drop below 41°F (5°C) and halts once safe levels are reached.
- Integrated Bluetooth Monitoring: Use the dedicated companion iOS/Android app to safely toggle battery power on/off and keep an eye on real-time State of Charge (SOC), voltage, current, and temperature limits.
- Advanced BMS Safeguards: An industrial-grade Smart Battery Management System protects your system round-the-clock against overcharging, over-discharging, short circuits, overcurrent, and thermal anomalies while maintaining cellular balance.
- Ultra-Lightweight Profile: Weighing only 24 lbs, this compact unit packs twice the energy density of an AGM or flooded lead-acid battery at just one-third of the physical weight.

Versatile 3-Way Charging Options
The Alpha 1 LiFePO4 battery integrates smoothly into your current system design. Charge your battery bank efficiently through three distinct configurations:
- Dedicated LiFePO4 Smart Charger: Approximately 6 hours using a standard 14.4V 20A (0.2C) battery charger configuration.
- Off-Grid Solar Panels: Fully charge in 1 optimal sunny day utilizing a solar array matching or exceeding 400W paired with a reliable MPPT controller.
- Alternator or Generator: Safely recover capacity in roughly 6 hours via an on-board generator or alternator setup connected with a 20A DC-to-DC battery charger.
Frequently Asked Questions
What is the benefit of the internal heating technology on the Alpha 1?
Lithium iron phosphate batteries cannot safely take a charge in freezing conditions without damaging the cells. The Rich Solar Alpha 1 features built-in thermal element pads. If charging current is present and internal temperatures dip under 41°F (5°C), the system safely warms up the battery cells to above 50°F (10°C) before allowing charging currents to engage, protecting your off-grid investment.
Can I track the battery status from my smartphone?
Yes. The standard Alpha 1 series incorporates an integrated Bluetooth chip. Simply scan the battery's unique barcode label through the mobile application (available on iOS and Android) to view current capacity metrics, active amp metrics, internal cell temperatures, and turn power off or on remotely.
How long will a 100Ah lithium battery power my devices?
The Alpha 1 holds 1,280 Watt-hours (Wh) of power. To calculate runtime, divide 1,280 by the wattage load of your appliance. For example, an efficient 50-watt RV television can run continuously for up to 25.6 hours on a single charge.
