Rich Solar ALPHA 2 LITE 12V 200Ah LiFePO4 Battery
The Rich Solar ALPHA 2 LITE is a value-focused 12V 200Ah lithium iron phosphate battery built for RVs, trailers, vans, boats, cabins, camping setups, and off-grid solar systems. With 2560Wh of nominal energy, 4,000+ cycles at 80% DoD, durable LiFePO4 cell construction, BMS protection, and a compact 52.9 lb design, it gives 12V power systems a dependable lithium upgrade without overcomplicating the build.
ALPHA 2 LITE: size your 12V RV or off-grid battery bank
One ALPHA 2 LITE stores 2,560Wh nominally at 12.8V and 200Ah. Its 200A maximum continuous discharge is a battery-side limit. Inverter losses, wiring, temperature and the reserve you keep reduce usable AC energy; watt-hours do not guarantee appliance runtime.
Cold-weather protection without a heater
This LITE model has no internal heater or Bluetooth. Its low-temperature charging protection can interrupt charging in cold conditions. The published charging operating range is 32–131°F (0–55°C); protection thresholds are not permission to charge frozen cells.
Choose the charging system and installation space
The current series sheet recommends 100A charging and lists 200A maximum charging current. Use a LiFePO4-compatible charger or solar charge controller, with a 14.2V recommended charge voltage and 14.4V maximum in that sheet. Solar panels do not connect directly to the battery without charge regulation.
Case dimensions: 20.9 × 8.1 × 8.5 in. Published net weight: 52.9 lb. Leave room for terminals, cable bends and service access. The manufacturer documents up to four same-model batteries in parallel; this is not permission to mix LITE/PRO models or assume series wiring is supported.
Discharge setting note: the linked model manual lists an 11.2V nominal discharge cutoff, while the August 2026 family sheet lists 10.0V. Confirm the applicable supplied-revision setting before changing a charger or inverter cutoff; the lower published number is not an instruction to discharge further.
What’s included
- 1 × ALPHA 2 LITE LiFePO4 battery
- 2 × M8 × 12 mm combination screws
- 2 × M8 × 16 mm combination screws
- 2 × M8 × 20 mm combination screws
- 1 × ALPHA 2 LITE user manual

Compare features and warranty
LITE’s 4,000+ advertised cycles are stated at 80% depth of discharge. Those different test conditions are not a like-for-like service-life guarantee. The 5-year warranty is prorated, subject to RICH SOLAR’s limited-warranty terms.

Product Overview
The ALPHA 2 LITE is designed for customers who want a practical 12V lithium battery with strong storage capacity and dependable protection, without paying for extra premium features they may not need. It is a strong fit for RV solar battery banks, camper vans, travel trailers, boats, small cabins, sheds, and backup energy storage setups.
Compared with traditional lead-acid batteries, LiFePO4 chemistry offers longer service life, more usable energy, lower maintenance, and a lighter footprint. The ALPHA 2 LITE keeps the setup simple while delivering enough storage for serious mobile, marine, and off-grid power needs.
Built for RV, Marine, Cabin, and Off-Grid Power
The ALPHA 2 LITE gives 12V power systems a strong lithium storage upgrade with the capacity and protection needed for real travel, backup, and off-grid use. It works well for customers who want reliable battery storage for solar charging, lighting, electronics, DC loads, and inverter-supported essentials.
Key Features That Matter
The ALPHA 2 LITE keeps the focus on the features customers actually care about when choosing a 12V lithium battery: longer battery life, safer operation, usable capacity, compact sizing, and dependable LiFePO4 performance.
Built for 4,000+ cycles at 80% DoD, the ALPHA 2 LITE is designed to maintain consistent performance through years of regular use. That makes it a smart upgrade for customers who want longer-lasting storage than traditional lead-acid batteries.
The ALPHA 2 LITE is designed for real-world mobile and off-grid conditions. Low-temperature and overheat safety support helps make it practical for RV compartments, trailers, cabins, and seasonal power systems.
The built-in battery management system helps protect against overcharge, over-discharge, over-current, short-circuit conditions, and high or low temperature issues. That added protection is important for solar, mobile, marine, and backup power systems.
At 52.9 lb with a compact 20.9 x 8.1 x 8.5 in footprint, the ALPHA 2 LITE is easier to place in RV compartments, trailers, boats, and small off-grid setups while still delivering 2560Wh of lithium storage.

ALPHA 2 LITE: compare the versions
Each ALPHA 2 LITE stores 2,560Wh nominally in a 12V-class, 200Ah battery. The versions below share the same nominal capacity; heating, monitoring and cycle ratings distinguish them.
| Model | Bluetooth | Internal heater | Advertised cycles |
|---|---|---|---|
| ALPHA 2 LITE | No | No | 4,000+ (80% DoD) |
| ALPHA 2 | Yes | Yes | 5,000+ (80% DoD) |
| ALPHA 2 PRO | Yes | Yes | 7,000+ (70% DoD) |
Cycle ratings depend on the manufacturer’s test conditions and do not guarantee identical service life. Nominal watt-hours describe stored energy; inverter losses and your chosen discharge reserve reduce usable AC energy.
The current ALPHA 2 series datasheet lists 14.2V recommended charging, 14.4V maximum and 200A maximum continuous discharge. Match the charging setup to the supplied battery revision and temperature limits in its manual.
