800Ah 12V LiFePO4 Off-Grid Battery Kit 10.2kWh Deep Cycle for RVs and Off-Grid Use

Product Overview

The ALPHA 2 LITE is a 12V 800Ah LiFePO4 battery designed for reliable, high-capacity energy storage. Built with premium lithium-iron-phosphate cells, it provides consistent performance, low maintenance, and long-term durability. With an 800Ah capacity, it delivers 10.24kWh of energy per unit, making it suitable for off-grid setups, RVs, vans, and modular battery banks.

The ALPHA 2 LITE combines efficiency, stability, and safety features to support energy storage solutions where dependability is a priority.

Why This Product Makes Sense

Reliable energy requires both performance and protection. The ALPHA 2 LITE uses premium LiFePO4 cells to deliver more than 4,000 cycles of dependable energy. Its long lifespan allows for accurate planning and confidence in long-term energy needs.

Each battery supports high amp loads with a stable voltage output. The Group 24 form factor makes it easy to integrate into larger battery banks or existing systems while maintaining predictable performance. This is particularly useful for users connecting multiple units to achieve higher total capacity.

Safety is built-in. The battery includes a BMS with individual cell fuses, overcharge and over-discharge protection, short circuit safeguards, and temperature-based disconnects. These systems help maintain stable operation and minimize risk, reducing concerns associated with less robust options.

The ALPHA 2 LITE is designed to operate across a wide range of temperatures: -4℉ to 140℉ for discharging and 32℉ to 131℉ for charging. Storage conditions up to 113℉ are supported for extended periods, ensuring reliability in diverse environments.

Removable carry handles and a thoughtful design make handling manageable despite the battery’s high capacity. When multiple units are used together in an 3200Ah 12V battery bank, the system provides modular, predictable energy storage with simplified connections.

What To Expect From It

Each ALPHA 2 LITE battery delivers stable 12.8V output and 800Ah capacity, totaling 10.24kWh. Self-discharge is less than 5% per month, ensuring energy remains available even after periods of inactivity.

The BMS continuously monitors individual cells, allowing the battery to continue functioning even if a single cell experiences a fault. Overcharge, over-discharge, overcurrent, and short circuit protections maintain safe, stable operation, while high and low temperature disconnects help protect the system under varying environmental conditions.

Handling and positioning are practical thanks to the removable carry handles and compact dimensions. Using four units with the included 1ft 2 AWG cables creates a 3200Ah 12V battery bank, delivering cumulative energy storage with consistent and reliable output.
