ALPHA 2 12V 200Ah LiFePO4 Battery for RVs and Off-Grid Use

Product Overview

The ALPHA 2 12V 200Ah LiFePO4 battery is a high-capacity, long-life energy solution for RVs, vans, boats, and off-grid cabins. With 12.8 volts and 200 amp hours of storage, it delivers approximately 2,560 watt hours of energy in a Group 31 case, designed to fit common RV and marine battery slots. This battery provides a reliable house bank without the maintenance demands of traditional lead acid systems.

Why This Product Makes Sense

The ALPHA 2 uses LiFePO4 cells rated for around 5,000 charge and discharge cycles, providing long-term reliability for daily solar use or occasional outages. Its stable, non-explosive chemistry and ABS housing, rated IP65, protect the battery from dust and low-pressure water jets in practical installations. This makes it a dependable core for any 12V system, feeding inverters, DC loads, and charge controllers without constant monitoring.

With 200 amp hours of capacity, it suits users who require a true house bank. Nominal voltage is 12.8 volts, nominal energy is 2,560 watt hours, and the integrated battery management system supports up to 100 amps continuous discharge. Charge voltage is 14.4V ±0.2V, compatible with lithium-capable chargers and MPPT controllers, and short-term surges of 110 amps are supported for brief peak loads.

Cold weather challenges are managed with an internal 100-watt heating system. Below 41°F (5°C), the heater draws from an external source to safely warm the cells, turning off above 50°F (10°C) so normal charging can continue. The battery is rated for charging from 32°F to 131°F, discharging from -4°F to 140°F, and storage from 14°F to 113°F, making it suitable for variable environments in RV bays and cabins.

The onboard battery management system handles day-to-day protection, monitoring overcharge, overdischarge, overcurrent, short circuit, and temperature, while balancing the cells to maintain long-term health. Integrated Bluetooth monitoring allows real-time tracking of state of charge, voltage, current, temperature, and remaining capacity. Users can also switch the battery on or off remotely from their phone for added convenience.

What To Expect From It

Physically, the ALPHA 2 measures 20.9 x 8.1 x 8.5 inches, fitting standard Group 31 compartments, and weighs about 48.5 pounds—substantially lighter than an equivalent lead acid bank. The ABS plastic housing provides durability and flame retardance, with a five-year manufacturer warranty included.

In use, the ALPHA 2 provides stable, long-term energy for high-capacity 12V systems. It quietly powers inverters, DC loads, and solar controllers while the integrated heating, BMS, and Bluetooth monitoring simplify daily operation. The battery’s large capacity and reliable chemistry ensure you can depend on it in RVs, boats, and off-grid cabins without constant maintenance.
