Heated 12V 200Ah Lithium Battery

Heated 12V 200Ah Lithium Battery — CLI200-12LT

Heated 12V 200Ah lithium battery engineered for serious off-grid energy storage — the Canbat CLI200-12LT delivers 2,560Wh of usable LiFePO4 power for larger RV systems, substantial marine house banks, high-demand inverter applications, and off-grid installations that require multi-day autonomy with significantly reduced generator dependency. With 200A continuous discharge, integrated charge-activated heating to -20°C (-4°F), and a Group 4D footprint, this is a purpose-built energy storage platform for systems that demand more than compact batteries can provide.

For fifth wheels and large Class A motorhomes running residential loads, for marine house banks powering full onboard electrical systems, for off-grid cabins with substantial solar arrays, and for serious van and overland builds where maximum energy density matters — the CLI200-12LT provides the capacity to run heavy overnight loads, sustain large inverter draws, and recover fully from a single charge source without compromise. The integrated heating system ensures that charging capability is never lost to cold weather, regardless of where the system is installed or how long it sits between visits.

It ships free across Canada and the USA with same-day dispatch, carries a 10-year warranty, and is built with UL 1642 certified cells. For Canada and USA orders, there are no import duties or cross-border complications.

Replacing Large AGM Battery Banks — In a Single Unit

A single CLI200-12LT delivers 2,560Wh of fully usable energy. To match that usable output from a conventional AGM battery bank — where depth of discharge is typically limited to 50% to protect cycle life — would require 400Ah of nominal AGM capacity. That means two large Group 4D AGM batteries, each weighing 130–160 lbs, with all the associated wiring, mounting hardware, maintenance requirements, and installation complexity of a dual-battery bank.

The CLI200-12LT replaces that entire setup in a single 51 lb (23.13 kg) unit. Same Group 4D footprint. Same battery tray. A fraction of the weight — without the watering, corrosion, and maintenance requirements associated with AGM banks. And critically — full charging capability year-round, including through Canadian winters when AGM batteries lose significant capacity and standard lithium batteries cannot accept a charge at all.

For system builders replacing aging AGM banks in RVs, boats, or off-grid installations, the CLI200-12LT is not a like-for-like battery swap — it is a system upgrade that delivers more usable energy, less weight, longer cycle life, and cold-weather charging capability in a single installation event.

Why Standard Lithium Batteries Cannot Charge Below Freezing

Standard LiFePO4 batteries can discharge normally in cold temperatures — inverters run, loads operate, the system functions. The problem is charging. Charging a lithium battery below 0°C (32°F) causes lithium plating on the anode — permanent cell damage that reduces capacity and accelerates degradation with every cold-weather charge cycle. To prevent this, standard lithium batteries block charging below 0°C entirely.

For a 200Ah battery installed in a serious off-grid or marine system, this limitation is operationally critical. A large solar array producing power on a clear January day cannot replenish the bank. Shore power at a cold marina or campground cannot recharge the system. A generator running on a cold morning cannot top up the reserve. The energy source is available — but the battery cannot accept it. Through a Canadian winter, this means the system arrives at spring significantly depleted, having missed weeks of available charging while loads continued drawing from a bank that could not recover.

The CLI200-12LT eliminates this limitation. Its integrated heating system activates automatically when the charger connects and the BMS detects temperatures below 0°C — warming the cells to a safe temperature before charging begins, without any user input required.

How the Built-In Heating System Works

Once the battery detects temperatures below freezing, the integrated heating system automatically prepares the cells for safe charging before current reaches the lithium cells. The system draws power from the incoming charging source — not from the battery’s stored energy — so the heating process does not reduce usable capacity or system reserve. The system operates in four automatic stages:

This process enables safe charging down to -20°C (-4°F) — covering the majority of Canadian winter conditions and ensuring the system captures every available charging opportunity from solar, shore power, or a generator regardless of ambient temperature. Discharge operation continues normally in cold temperatures regardless of heating system status.

Applications

Large RV Systems — Fifth Wheels & Class A Motorhomes

Fifth wheels, Class A motorhomes, and large travel trailers running residential-grade loads — induction cooktops, residential fridges, air conditioning, entertainment systems, and electric slide mechanisms — require energy storage that matches the load. The CLI200-12LT provides 2,560Wh of usable overnight reserve in a single Group 4D unit, significantly reducing generator dependency and enabling extended boondocking without the weight, maintenance, and charging limitations of large AGM banks. The heating system ensures shore power and solar charging remain active through winter storage and cold-climate travel.

Serious Marine House Banks

For larger sailing vessels, liveaboards, and powerboats where the house bank must sustain autopilot, radar, chart plotters, refrigeration, watermakers, communications, and full cabin lighting through extended passages or multi-night anchorages, the CLI200-12LT delivers the reserve capacity to keep systems operational through the night without generator intervention. Sealed, maintenance-free, and IP54-rated for marine environments — with no off-gassing in confined bilge spaces and no corrosion on terminals or cases.

Off-Grid Cabins & Solar Storage

For off-grid cabins and remote properties with larger solar arrays, the CLI200-12LT provides the storage depth to sustain full household loads through extended periods of low solar production — cloudy weeks, short winter days, and seasonal low-angle sun. The integrated heating system captures charge from solar panels on clear winter days even when the cabin is unoccupied and unheated, ensuring the bank arrives at full capacity when owners return.

High-Capacity Van & Overland Builds

For full-time van dwellers and serious overland builds where the electrical system is the primary infrastructure — running induction cooktops, espresso machines, hair dryers, power tools, laptop workstations, and high-draw appliances — the CLI200-12LT provides the energy reserve to sustain these loads over multiple days without shore power access. At 51 lbs it significantly reduces the weight of equivalent AGM capacity while providing substantially more usable energy in the same installation space.

Commercial Auxiliary & Remote Industrial

For service vehicles, utility trucks, remote monitoring stations, telecom backup systems, and pipeline infrastructure sites operating in Canadian winters, the CLI200-12LT’s combination of high capacity, sustained discharge capability, and cold-weather charging makes it a reliable foundation for critical systems that cannot afford a depleted battery or a missed charging cycle between service visits.

The CLI200-12LT is Canbat’s serious off-grid heated lithium battery — a Group 4D platform delivering 2,560Wh of usable energy for larger systems that have outgrown compact battery formats and require the depth, discharge capability, and winter charging reliability to operate year-round without compromise. It directly targets buyers replacing large AGM battery banks, upgrading undersized lithium systems, or specifying batteries for high-demand RV, marine, and off-grid applications where capacity and reliability are the primary requirements.

For Canadians sourcing a heated 12V 200Ah lithium battery, the CLI200-12LT ships free with no import duties, is backed by a Canadian technical team, and carries a 10-year warranty. Compatible with all major inverter/charger brands and solar charge controllers that support a LiFePO4 charging profile.

Runtime & Performance

The CLI200-12LT delivers 2,560Wh of usable energy at 12V nominal — all accessible at 100% depth of discharge on every cycle with stable voltage throughout. A standard Group 4D AGM battery, limited to approximately 50% usable depth of discharge, would need a nominal rating of 400Ah to approach this usable output:

Runtime figures are based on 100% usable depth of discharge. The CLI200-12LT delivers its full 200Ah on every cycle with no derating and stable voltage under sustained high-current loads — including at its 200A continuous discharge rating, a critical advantage for inverter systems where voltage sag causes appliances to shut down prematurely.

Series & Parallel Expandability

The CLI200-12LT supports both series and parallel connections — up to 4 units in either configuration — for systems that require greater capacity or higher system voltage. Every battery in the bank retains its integrated heating system, so cold-weather charging capability scales with the entire installation.

A four-unit parallel bank delivers 800Ah / 10,240Wh — a serious heated lithium energy storage system capable of running large off-grid homes, full-time liveaboard vessels, and high-demand mobile systems through multiple days of autonomy.

Technical Specifications

Battery Management System and Bluetooth Monitoring

The CLI200-12LT’s integrated BMS manages heating logic, cell-level protection, and balancing simultaneously — with no external battery management required. The system operates automatically in all conditions including the transition between heating and charging modes in sub-zero environments.

• Heating logic — automatically activates and deactivates the cell heater based on internal temperature readings; manages the transition between heating and charging modes
• Over-discharge protection — prevents cell damage from excessive depth of discharge
• Over-charge protection — disconnects at the correct voltage ceiling
• Short circuit and over-current protection — responds within milliseconds
• High-temperature cutoff — protects cells during charging in hot environments
• Cell balancing — maintains consistency across the prismatic cell groups over thousands of cycles

The optional Bluetooth add-on connects the battery to the free Canbat BT app, available for iOS and Android. Monitor state of charge, voltage, current, cell temperature, and heating system status in real time — particularly valuable for large off-grid installations, remote cabin systems, and liveaboard vessels where physical access to the battery compartment is limited and remote system visibility is operationally important.

System Compatibility and Installation

The CLI200-12LT is compatible with any inverter/charger, solar charge controller, or AC charger that supports a LiFePO4 charging profile. When replacing lead-acid or AGM batteries, verify that the charging system’s voltage settings are configured for lithium — incorrect lead-acid charge profiles will undercharge the battery or stress the cells over time. Most modern inverter/chargers and solar charge controllers include a LiFePO4 preset.

For alternator charging in vehicles or vessels, a DC-DC charger is strongly recommended to deliver correct LiFePO4 charging parameters and protect the alternator from the battery’s high charge acceptance rate. M8 terminals with bolts are included. The battery installs upright or on its side in any standard Group 4D tray, battery box, or marine compartment.
