12V 120Ah Pro Series – LiFePO4 Cranking & Deep Cycle Lithium Battery (California)

California boating demands a battery that can do more than “start the engine.” Between long days offshore, heavy electronics loads, and saltwater exposure, you need reliable cranking power and true deep-cycle performance in one tough package. The 12V 120Ah Pro Series is a dual-purpose LiFePO4 battery built to deliver strong engine-start bursts while also supporting sustained house loads—ideal for center consoles, bay boats, and offshore rigs running California’s coastline.

With IP67 waterproof protection, internal heating for sub-zero charging, Bluetooth monitoring, and an advanced BMS, this battery is engineered for dependable performance whether you’re launching before sunrise, running to the islands, or staying on the hook with systems powered up.

Dual-Purpose Power for California Boats

This battery is designed to combine cranking starter performance with deep-cycle endurance, so you can simplify your battery setup without sacrificing confidence at the dock or on the water.

  • Engine starting power: up to 800A for 10 seconds and approximately 1100 CCA, designed to be compatible with outboard motors up to 250hp
  • Deep-cycle capability: 150A max continuous discharge to support electronics, pumps, lighting, and onboard accessories throughout the day

Overview

  • IP67 waterproof and dustproof protection
  • Bluetooth monitoring with iOS and Android support
  • 6,000+ cycle life
  • Advanced smart BMS
  • Internal heating for cold-weather charging
  • Safe, reliable, maintenance-free operation

Cranking Performance You Can Trust

When you hit the key, the Pro Series is built to respond fast with high current output:

  • 800A @ 10s (SOC > 60%)
  • 800A @ 5s (SOC < 60%)
  • 600A @ 10s

That means confident starts even when you’ve been running accessories and electronics for hours. It’s also designed for strong cold-start behavior (noting that cranking performance is always influenced by temperature, wiring, and overall system condition).

Charging Flexibility with High Acceptance

For modern charging systems common on California boats—alternator charging, shore chargers, and DC-DC solutions—this battery is built to accept higher charge input when needed:

  • Max charge current (continuous): 100A
  • Peak charge acceptance: up to 165A (max for 1 minute)

Internal Heating for Cold-Weather Charging

Trailering to the mountains, winter storage, or early-season launches can put lithium charging into restricted temperature zones. This battery includes internal heating designed to support charging down to -20°C (-4°F), helping maintain usability when temperatures drop.

Bluetooth + Victron Communications

The Pro Series includes monitoring and integration features for modern power systems:

  • Bluetooth monitoring through iOS and Android apps
  • Over-the-air firmware updates via the app
  • Victron communications via CANBus for an entire string of batteries to interface with Victron Cerbo GX

Optional add-ons (when available) can expand system visibility and network integration:

  • 5″ touch screen battery gauge (optional)
  • NMEA2000 + inverter communications box (optional)

Advanced BMS Protection

A built-in smart BMS continuously monitors operating conditions and helps protect the battery and connected equipment:

  • Overcharge and over-discharge protection
  • Over-current and short-circuit protection
  • High- and low-temperature disconnects

System Expansion Options

Build a single-battery setup or scale into larger banks:

  • Up to (4) in series (up to 48V)
  • Up to (16) in parallel
