Key Performance Features
Advanced Battery Management System (BMS)
Each battery features a built-in intelligent BMS acting as your internal safety warden. It automatically protects cells against over-charging, extreme over-discharging, short-circuit faults, and thermal runaways, ensuring complete structural integrity during operation.
Rugged IP65 Weatherproof Structure
Encased in a UL94 V-0 flame-retardant ABS case, the entire unit boasts an IP65 waterproof and dustproof architecture. It easily withstands severe road vibrations, accidental water splashes, and harsh weather variables, keeping your primary energy bank safe.
Flexible High-Capacity System Scaling
Want a larger system? Expand your energy potential with up to 4 parallel and 4 series connections (4P4S configuration). Wire them together to quickly scale a basic 12V setup into a heavy-duty 24V or 48V power grid tailored precisely for your custom needs.

Frequently Asked Questions
Can I use the Standard or PRO version in below-freezing weather?
Yes! Both the ALPHA 3 Standard and PRO models include built-in internal heat technology. When the core temperature falls below 41°F (5°C) and a charging current is applied, the internal system draws power to safely heat the cells above freezing before accepting a charge. This prevents cold-charging damage.
What is the primary difference between the Rich Solar ALPHA 3 LITE and Standard models?
The LITE version offers a highly competitive price point by focusing entirely on basic power storage. It excludes Bluetooth wireless monitoring and internal heating pads, which are standard features on the regular ALPHA 3.
Why should I choose the ALPHA 3 PRO variant?
The ALPHA 3 PRO increases your usable capacity to 314Ah, provides an extreme lifecycle of over 8,000 charges, and holds a **UL 1973 Certification**. This certification is highly important for passing building inspections and meeting strict off-grid insurance compliance mandates.
How many hours will a single Rich Solar ALPHA 3 (300Ah) battery run my appliances?
The battery stores a total of 3,840 Watt-hours (Wh). For example, a typical 50W smart TV found in an RV can run continuously on this single battery for approximately 76 hours without requiring any solar recharge.
Can I connect multiple of these batteries together for more capacity?
Yes. These batteries are designed to be wired in parallel (same voltage, more capacity) or in series (for systems that support it) to build a larger battery bank, as long as you stay within the battery's documented max parallel/series configuration.
Is there a display or app for this battery?
Monitoring on this range is generally through Bluetooth to a phone app rather than an onboard screen, reading directly from the battery's management system. The specifications above confirm whether this model includes it.
How many years will this battery realistically last?
Work it back from cycles rather than years. At a rating in the thousands of deep cycles, a bank cycled once a day lasts well over a decade, while one cycled lightly lasts longer still. Lead-acid, by comparison, is often finished after a few hundred deep cycles.
Is this a drop-in replacement for my lead-acid or AGM battery?
Yes, in most cases. This 12V LiFePO4 battery is built to the same physical form factor and voltage as comparable lead-acid/AGM batteries, so it typically drops into the same battery box or compartment while delivering more usable capacity and a longer lifespan.
Does it have a built-in Battery Management System (BMS) for safety?
Yes. Rich Solar LiFePO4 batteries include an internal BMS that protects against overcharge, over-discharge, short circuits, and temperature extremes, which is part of why they're considered safer than lead-acid for enclosed spaces.
What size charger or solar controller do I need to charge this battery?
Use a charger or solar charge controller rated for 12V LiFePO4 batteries specifically (not a generic lead-acid profile) so the charging voltage and absorption curve match this chemistry. Match the controller's max charge current to the battery's rated capacity.
