B-TEC Slim 12V 300Ah LiFePO4 Battery by Enerdrive

Introducing the Enerdrive B-TEC Slimline 12V 300Ah LiFePO4 battery — a compact, high-capacity power solution built for serious off-grid loads in tight spaces. Perfect for RVs, boats, solar-powered builds, and compact fleets, it delivers dependable energy without sacrificing room.

  • Ultra-slim footprint: Dimensions of 630 mm (W) × 498 mm (H) × 176.5 mm (D) with all connections at one end for clean, simple panel layouts and easy cabling.
  • High-capacity LiFePO4 chemistry: Nominal 12.8V, 300Ah with a cycle life ≥2000 cycles at 80% DoD, designed for long-term off-grid resilience.
  • Rugged, water-aware enclosure: IP52-rated metal housing with moisture seals and overlapping frame to minimize ingress in demanding environments.
  • Remote reset and future-ready connectivity: Remote reset option keeps the reset function away from the battery, and RJ45 CAN ports are reserved for future expansion and monitoring enhancements.
  • Integrated smart monitoring: Wireless Battery Monitoring Technology (BMT) lets you track SOC, voltage, current, cell voltages, SOH, temperature, alarms, and event logs from iOS or Android devices.
  • Optimized charging and install ease: Standard lithium-profile charger compatibility; charging range 14.20–14.60V CV/CC, float 13.50–13.80V, with a maximum charging current of 150A at 25°C for rapid replenishment.
  • One-end connectivity: All connection points and communications ports are located at one end, simplifying cabling, panel design, and installation in confined spaces.

The Enerdrive B-TEC Slimline is designed for users who refuse to compromise on power density or reliability. Whether you’re running high-draw appliances in an RV, powering a marine auxiliary, or building a space-efficient off-grid solar system, this battery provides steady energy, precise monitoring, and confident performance over thousands of cycles. Its robust construction and advanced monitoring help you plan maintenance, predict longevity, and maximize run-time between charges.
