12V 173Ah LiFePO4 Battery | LiFePO4 Technology | Long-Lasting Power & Fast Charging

Product Overview

The GV12173T31B is a rugged, compact 12 V 173 Ah LiFePO₄ battery enclosed in a heavy-duty steel case. Engineered as a drop-in replacement for lead-acid, it combines built-in CANbus, RS-485, UART communications, Bluetooth monitoring, and automatic heating for rock-solid performance in RVs, yachts, fishing boats, and solar/off-grid installations—even in sub-zero conditions.

Key Features

• Industrial-Grade Iron Housing
  IP67-rated steel enclosure guards against vibration, salt spray, and moisture.

• Multi-Protocol Comms
  Native CANbus, RS-485, and UART ports integrate seamlessly with vehicle ECUs, solar inverters, and BMS networks.

• Bluetooth Diagnostics
  Instant wireless access to voltage, SoC, cell temperature, cycle count, and fault alerts.

• Automatic Heating Element
  Activates below 0 °C so you can safely charge down to 0 °C without manual intervention.

• High-Rate Discharge
  Continuous (150 A) and 2 C peak (346 A for 5 s) to power heavy loads on demand.

• Long Cycle Life
  ≥ 3,000 cycles at 80 % DoD—equivalent to over a decade of typical use.

• Compact Footprint
  Optimized dimensions and a low weight (≈ 18 kg) save space and improve handling compared to bulky lead-acid banks.

• Advanced BMS Protection
  Comprehensive safeguards against over-charge, over-discharge, over-current, short-circuit, and over-temperature.

Applications

• RVs & Camper Vans
  Run LED lighting, water pumps, HVAC, and entertainment systems—year-round, without the bulk of lead-acid.

• Marine & Yachting
  Ideal for trolling motors, navigation electronics, deck lighting, and winch systems.

• Solar & Off-Grid
  Scalable in series or parallel to build robust energy banks for cabins, tiny homes, and remote solar systems.

Installation & Use

• Drop-In Replacement
  Fits standard 12 V lead-acid trays and brackets—no custom fabrication required.

• Plug-Ready Interfaces
  M8 stainless power studs plus RJ45 (CAN) and screw-terminal (RS-485/UART) ports make wiring simple.

• Series & Parallel Configurations
  Wire up to four units in series (up to 51.2 V) or parallel (up to 692 Ah) with on-board BMS balancing.

• First-Charge & Pairing
  Shipped at ~50 % SoC—top up to 14.6 V with any LiFePO₄ charger, then power on Bluetooth and verify comms links.

• Maintenance-Free Operation
  No watering, no equalizing—periodic terminal inspections are all that’s needed.
