The Rich Solar ALPHA 3 PRO 12V 314Ah LiFePO4 Battery (model RS-B123SP) stores 4,019Wh at 12.8V and supplies up to 200A of continuous discharge current. Rich Solar rates it for more than 8,000 cycles at 80% depth of discharge and backs it with a 10-year limited warranty.
It's made for RVs, marine systems, off-grid cabins and backup power. The ALPHA 3 PRO is ETL certified to the UL 1973 standard for stationary and motive auxiliary power batteries, and it adds a 100W internal heater, Bluetooth monitoring through the RICH SOLAR app and an IP65-rated, flame-retardant case.
The Grade A+ LiFePO4 cells are rated for more than 8,000 cycles at 80% depth of discharge. With 4,019Wh per charge and monthly self-discharge of 5% or less, it suits systems you charge and discharge often. The LiFePO4 chemistry is maintenance-free.
The ALPHA 3 PRO carries the ETL mark for ANSI/CAN/UL 1973, the standard for batteries used in stationary and motive auxiliary power applications. Rich Solar also lists FCC, CE, UN 38.3 and MSDS for this model.
When the internal temperature reads 41°F or lower and a charger is supplying current, a 100W heater warms the cells. It shuts off at 50°F or when the charger is disconnected. The heater can't draw on the battery's own stored energy, and low-temperature charging protection releases on its own once the cells warm up.
The RICH SOLAR app shows state of charge, remaining capacity, voltage, current, power, each cell's voltage, temperatures and cycle count. History charts track voltage, current, capacity and temperature over time. A Control tab lets you switch charging or discharging on and off, and a Parameters tab records how many times each protection has triggered.
Charge at up to 200A, with 157A recommended, using a CC/CV charger set to 14.2V and never above 14.4V. The battery supplies up to 200A continuous, and the discharge cutoff is 10.0V.
The case is UL94 V-0 flame-retardant plastic with an IP65 rating. Inside, the BMS guards against over-charge, over-discharge, charge and discharge over-current, short circuits, unsafe charging or discharging temperatures and internal FET overheating, and it balances the cells passively.
Link up to four ALPHA 3 PRO batteries in parallel (4P), and the app includes a parallel connection menu. M8 terminals take 97.4 ± 10.6 lbf·in of torque, and rope handles on both ends help you set the 71.7 pound battery in place.
RVs and motorhomes. Run a 12V house system from 4,019Wh, keep charging in cold weather and watch the battery from your phone.
Off-grid cabins. Build a 12V bank of up to four UL 1973 certified batteries with a 10-year limited warranty.
Boats. Rich Solar lists marine systems among its uses, and the IP65-rated case adds protection against dust and water.
Home backup. Keep a 12V backup bank ready and use the app's charge and discharge switches during maintenance.
Reaching 314Ah with smaller batteries means more units, more cables and more connections to check. One ALPHA 3 PRO gives you 314Ah and 4,019Wh in a single 20.5 x 10.6 x 8.7 inch case with one BMS and one app connection, and you can still add up to three more later.
Without a heater, a LiFePO4 battery can't charge safely until its cells warm above freezing. The ALPHA 3 PRO warms itself from 41°F up to 50°F using charging power, so charging can continue through winter.
Set the battery upright with the terminals facing up. Don't mount it on a wall without a mounting bracket. For parallel banks, charge each battery fully on its own first so they're within 1V of each other, use cables of equal length and size, and never mix brands or models. Rich Solar calls for a qualified electrician to make the connections.
Stay at or below 200A and 14.4V when charging. The battery ships at about 30% state of charge by air or about 50% by sea. For storage over three months, keep it between 50°F and 95°F, charge and discharge it every three months and hold it at 40 to 50% state of charge.
Install the RICH SOLAR app from the App Store or Google Play, turn on Bluetooth and Location Services, then tap Add Now and pick the battery with the strongest signal. A QR code on the side of the battery links to the app download, and the device address on the battery helps when several batteries show up.
Yes, while a charger is connected. The heater turns on at 41°F or below and off at 50°F, then normal charging continues. Charging is rated for 32°F to 131°F and discharging for -4°F to 140°F.
The BMS has switched the battery off to protect it after an over-discharge, over-charge or over-current event. A lithium-compatible charger detects the low voltage, wakes the BMS and resumes charging.
Rich Solar backs the ALPHA 3 PRO with a 10-year limited warranty.
The Rich Solar ALPHA 3 PRO 12V 314Ah LiFePO4 Battery pairs 4,019Wh and 200A output with UL 1973 certification, an 8,000+ cycle rating, built-in heating, app control and a 10-year limited warranty.
