B-tec Gen2 12V 100Ah LiFePO4 Battery — Deep‑Cycle Power for Off‑Grid Living

Meet the B-tec Gen2 12V 100Ah LiFePO4 Battery, a rugged, high‑capacity deep‑cycle power solution crafted for off‑grid living, campers, caravans, and auxiliary power on demanding sites. Built on Enerdrive’s Gen2 platform, this 12V unit delivers dependable energy where you need it most and scales to fit growing power needs.

Smart, real‑time energy management at your fingertips. The battery features built‑in monitoring that communicates with Android and iOS apps, giving you real‑time visibility into state of charge (SOC), state of health (SOH), voltage, current, temperatures, cycle history, alarms, and more—from your phone. This level of insight helps you optimize charging, protect the pack, and plan energy usage for longer trips.

Reliability you can trust. The B‑TEC Gen2 is equipped with a robust LiFePO4 Battery Management System (BMS) that actively guards against overcharge, over‑discharge, overtemperature, and short circuits, maximizing safety, longevity, and performance in remote or rugged environments. A dedicated wake‑up button lets a dormant pack come back online quickly, supporting fast charging and minimal downtime on the road.

Compact, purpose‑built design for tight spaces

Designed for practical installations in caravans, campers, and off‑grid setups, the Gen2 100Ah model comes in a compact, rugged enclosure measuring approximately 295 mm (L) x 86 mm (W) x 206 mm (H). Its space‑efficient footprint makes it straightforward to fit where space is at a premium, while its durable construction stands up to daily use in adventurous environments.

Why this matters for your adventures

If you’re powering a camper trailer, caravan, 4WD auxiliary setup, or a remote work site, the B‑TEC Gen2 delivers longer runtimes, safer charging, and easier integration than traditional lead‑acid systems. The combination of high usable energy, a lightweight footprint, and a compact form factor translates to simpler installs, more flexible layouts, and reliable power when you need it most. The built‑in app monitoring and robust BMS turn everyday charging into smart, informed energy management.

Ideal applications

  • Camper trailers and caravans needing dependable 12V power for refrigeration, lighting, pumps, fans, and electronics
  • 4WD auxiliary battery setups for extended off‑grid use and remote adventures
  • Small watercraft or remote work sites where safe, long‑lasting energy storage matters

The Enerdrive Gen2 family is designed to grow with your system, offering scalable capacity and configuration options to match increasing energy needs without compromising safety or performance.

Practical tips to get the most from your B‑TEC Gen2

  • Pair with lithium‑specific chargers to ensure optimal charging profiles and maximize cycle life
  • Use the smartphone monitoring to track SOC and plan recharges around use patterns, especially on off‑grid trips
  • Follow the safety note: if the battery is fully discharged and the BMS is off, recharge within 14 days to protect cells and sustain performance

With its deep‑cycle design, premium safety features, and real‑time visibility, the B‑tec Gen2 12V 100Ah LiFePO4 Battery is a dependable power partner for off‑grid adventures and remote work setups—delivering longer runtimes, simpler installations, and smarter energy management day after day.
