Our take on the ALPHA 1 12V 100Ah LiFePO4 Battery

The RICH SOLAR ALPHA 1 is a 12V 100Ah lithium iron phosphate battery rated at 1280Wh, aimed at RV, van, boat, cabin and off-grid power systems. It stands out with built-in self-heating that kicks in below 41°F, Bluetooth monitoring through an app, and a BMS covering overcharge, overdischarge, overcurrent, short circuit, cell balance and temperature. It weighs 24 lb, roughly a third of a comparable lead-acid bank, and is rated for 5,000-plus cycles. Against rival 100Ah LiFePO4 batteries, the cold-weather heating and app monitoring are the differentiators; the 100A continuous discharge and charge limits are typical for the class rather than exceptional.

Pros
  • Internal heating allows charging below 41°F
  • Bluetooth app shows state of charge, voltage, current and temperature
  • 5,000-plus cycle rating, far longer than lead-acid
  • Full BMS protection set including cell balance
  • 24 lb, about a third of equivalent lead-acid weight
  • Charges from LiFePO4 charger, solar or a DC-DC charger
Cons
  • 100A charge and discharge limits cap big inverter loads
  • Heating draws on the battery in cold conditions
  • App pairing depends on scanning the battery barcode
  • No built-in DC-DC charging; a separate charger is needed

About the ALPHA 1 12V 100Ah LiFePO4 Battery

The ALPHA 1 is a 12V 100Ah lithium iron phosphate (LiFePO4) battery from RICH SOLAR. It uses A+ grade EV-grade cells and is intended for RVs, trailers, vans, boats, cabins and off-grid systems. It is lighter than a lead-acid battery, at about one third of the weight, with twice the energy density.

A built-in BMS protects against overcharge, over-discharge, over-current, short circuit and temperature extremes, and balances the cells. An internal heater starts below 41°F (5°C) so the battery can charge in cold weather. It stops above 50°F (10°C). Charging is off below 32°F (0°C).

Bluetooth lets you monitor the battery in a smartphone app. The app shows state of charge, voltage, current, temperature and remaining capacity, and it can turn power on and off. You pair by scanning the barcode on the battery. The battery can be charged with a LiFePO4 charger, solar panels or a generator through a DC-DC charger.

Questions and answers

Can the ALPHA 1 be charged in freezing weather?
Yes, down to 32°F. Internal heating activates automatically below 41°F so charging stays safe in cold climates. Discharge works from -4°F to 140°F.
How long does it take to charge?
About 6 hours on a 14.4V/20A LiFePO4 charger, or roughly one sunny day with more than 400W of solar. A 20A DC-DC charger from a generator also takes about 6 hours.
What can a 100Ah battery like this run?
It stores 1280Wh. The 100A discharge limit suits moderate inverter loads; large appliances that pull more than 100A continuously will trip the BMS.
Does it work with my existing lead-acid setup?
It is a drop-in 12V replacement in size and voltage, but charge profiles differ. Use a lithium-compatible charger or solar controller set to 14.4V.
What is in the box?
The battery itself. A LiFePO4 charger, solar panels or a DC-DC charger are separate purchases.
How do I monitor it?
Pair the battery's barcode with the Bluetooth app to see state of charge, voltage, current, temperature and remaining capacity, and to switch power on or off.
Where is the ALPHA 1 12V 100Ah LiFePO4 Battery cheapest?
At Solar Cellz USA, for $249.99, 47% under what the other stores charge, as of our latest check.
What do buyers say about the ALPHA 1 12V 100Ah LiFePO4 Battery?
Rated 5 out of 5 from 9 ratings.
Where can I buy the ALPHA 1 12V 100Ah LiFePO4 Battery?
12 stores we checked sell it, including Outbound Power, Rich Solar, Solar Cellz USA, SolarTown, Solaris.
