0Ah to 100Ah Batteries

0Ah to 100Ah Deep Cycle Batteries for Caravans, 4WDs, Marine & Off-Grid

When space and weight are at a premium, a compact deep cycle battery in the 0–100Ah range delivers dependable energy storage without compromising your payload. Our curated selection covers 12V, 24V, and 48V lithium (LiFePO4), AGM, and gel technologies, purpose-built for Australian conditions. Whether you are running a 12V fridge in a dual-cab canopy, powering a trolling motor on a tinny, or building a lightweight portable solar kit, these batteries provide the cycle life and consistent voltage you need.

How to choose: Start with your daily energy consumption (Ah or Wh) and the available space in your battery bay. Then match the chemistry to your charging system and budget. If you are unsure, the quick decision guide below will help you narrow down the best option.

Battery Chemistries Explained

Lithium Iron Phosphate (LiFePO4)

Best for: Frequent cycling, weight-sensitive builds, and smart system integration.

Lithium deep cycle batteries in the 0–100Ah class offer a significant weight saving over lead-acid equivalents, often halving the mass for the same usable capacity. Models with integrated Bluetooth monitoring, such as the Exotronic Alpha IP67 series and Victron Smart LiFePO4 range, allow you to track state of charge, voltage, and cycle history directly from your phone. High continuous discharge ratings on selected units support inverter loads up to 2000W or more, making them suitable for running induction cooktops or coffee machines off-grid.

• Key benefit: Up to 80% depth of discharge without reducing cycle life.
• Typical use: Caravan house batteries, 4WD dual-battery systems, portable power packs.

AGM (Absorbent Glass Mat)

Best for: Budget-conscious builds, engine bay installations, and simple charging systems.

AGM batteries remain a popular choice for their vibration resistance, maintenance-free operation, and lower upfront cost. Our 0–100Ah AGM range includes deep cycle and dual-purpose marine units with CCA ratings for starting and cycling, ideal for boats and 4WDs where a single battery must handle both tasks. Brands like Victron, Century, and Power-Sonic offer proven reliability in this segment.

• Key benefit: Excellent value per amp-hour and wide temperature tolerance.
• Typical use: Camper trailers, marine house banks, backup power.

Gel

Best for: Deep cycling in extreme temperatures and applications where spill-proof construction is critical.

Gel batteries excel in slow, deep discharge scenarios and can tolerate higher ambient temperatures better than standard AGM. The Victron Gel and Century Gel options in our 0–100Ah lineup are well-suited to remote solar installations and marine environments where maintenance access is limited.

• Key benefit: Superior deep-cycle endurance and low self-discharge.
• Typical use: Remote monitoring stations, sailing yachts, off-grid cabins.

Voltage Options: 12V, 24V, 48V

While 12V remains the standard for most caravans and 4WDs, higher-voltage systems are gaining traction for their efficiency advantages.

• 12V nominal: Compatible with the widest range of appliances, chargers, and inverters. Ideal for single-battery setups or parallel banks.
• 24V nominal: Reduces current draw for the same power output, allowing thinner cabling and lower voltage drop. Common in larger boats, trucks, and some off-grid homes.
• 48V nominal: Emerging standard for high-power inverters and all-in-one energy systems. Our 48V 50Ah and 100Ah lithium options support these advanced architectures.

Key Features to Consider

• Bluetooth monitoring: Many lithium models include built-in Bluetooth for real-time data via a smartphone app, eliminating the need for a separate battery monitor.
• IP67 rating: Dust-tight and protected against temporary immersion, important for marine and under-bonnet installations.
• Slimline form factors: The Exotronic 100Ah Slimline and Enerdrive B-TEC Slim Case fit tight compartments where standard case sizes won’t go.
• High CCA dual-purpose: Century Marine Pro and Invicta Hybrid lithium batteries provide both cranking amps and deep cycle capability, perfect for 4WDs and boats that need a single-battery solution.
• SuperPack integration: Victron SuperPack batteries include an internal BMS and safety contactor, simplifying installation with no external relays required.

Quick Decision Guide

• Need maximum usable capacity in a lightweight package? Choose a lithium battery with Bluetooth, such as the Exotronic Alpha or Victron Smart series.
• Working with a tight budget or high under-bonnet temperatures? An AGM deep cycle battery offers reliable performance at a lower price point.
• Requiring a battery that can start an engine and run accessories? Look for dual-purpose AGM or lithium hybrid models with a CCA rating.
• Building a 24V or 48V system? Select a matching voltage battery to avoid series wiring complexity.

Installation and System Compatibility

All batteries in this collection are compatible with leading solar charge controllers, DC-DC chargers, and inverter chargers. For lithium batteries, ensure your charging sources support a LiFePO4 profile (typically 14.2–14.6V absorption for 12V systems). Pairing a 100Ah lithium battery with a quality MPPT solar controller and a DC-DC charger with smart alternator compatibility will maximise your energy harvest and battery lifespan. Browse our range of MPPT solar controllers and DC-DC chargers to complete your system.
