12.8V 100Ah LiFePO4 Battery | LiFePO4 Technology | Long-Lasting Power & Fast Charging

Product Overview

The GreatVolt 12.8 V 100 Ah LiFePO₄ Battery (GV12100T31) is a heavy-duty, iron-cased drop-in replacement for 12 V lead-acid banks, now with integrated CANbus, RS-485, UART communications, Bluetooth monitoring, and an on-board heating element. Engineered for extreme environments—from sub-zero winters in your RV to salt-spray decks on your yacht—this battery delivers clean, reliable power for RVs, marine vessels, and solar/off-grid systems.

Key Features

• Industrial-Grade Iron Enclosure
  Rugged cold-rolled steel housing with IP67 sealing for vibration and water-resistance.

• Multi-Protocol Communications
  Native CANbus, RS-485, and UART ports allow seamless integration with vehicle or solar controllers.

• Bluetooth Smart Monitoring
  Real-time read-outs of voltage, state-of-charge, cell temperature, and cycle count.

• Auto-Heating Function
  Automatic heater activation below 0 °C, enabling safe charging down to 0 °C.

• Extended Cycle Life
  ≥ 3,000 cycles at 80 % DoD—translating to 7–10 years of typical use.

• High Discharge Capability
  100 A continuous (1 C) and 200 A peak (2 C for 5 s) for heavy-load starts and onboard systems.

• Advanced BMS Protection
  Over-charge, over-discharge, over-current, short-circuit, and over-temperature safeguards built in.

• Lightweight Efficiency
  At just 12 kg, over 60 % lighter than equivalent lead-acid banks, improving fuel economy and handling.

Applications

• RVs & Camper Vans
  Ideal for running lighting, water pumps, HVAC, and entertainment systems—year-round, even in cold climates.

• Marine & Yachts
  Perfect for trolling motors, navigation electronics, deck lighting, and auxiliary power on fishing boats and yachts.

• Solar & Off-Grid
  Build scalable banks (series/parallel) for cabins, tiny homes, and remote solar installations with full system communications.

Installation & Use

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

• Plug-Ready Terminals
  M8 stainless studs for power, plus dedicated RJ45 and screw-terminal ports for CAN, RS-485, and UART.

• Series & Parallel Configurations
  Safely wire up to 4× batteries in series (25.6 V, 38.4 V, 51.2 V) or parallel (up to 400 Ah) with on-board BMS balancing.

• First-Time Setup
  Arrives at ~50 % SOC—top off with a LiFePO₄ charger (14.6 V float). Activate Bluetooth monitoring and verify comms link to your control system.

• Hassle-Free Operation
  No watering or equalizing needed. Periodic terminal checks for torque and corrosion are all that’s required.
